Logitech M570 Wireless Trackball Mouse – Ergonomic Design with Sculpted Right-Hand Shape, Compatible with Apple Mac / Microsoft, USB Unifying Receiver, Dark Gray

I bought one of these back in 2007, and put in a AA. I had no idea at the time that I had just purchased something that would be with me for a LONG time. To be honest, I've got ADHD and ASD, and the shiny blue, perfectly round heavy ball looked amazing to play with, and super tempting. I told myself I would NOT play with this fancy toy until the mouse broke. This would be a very long exercise in keeping my word to myself and resisting temptation. This mouse was super easy to use, I just plugged in the little dongle, and it was ready to go. Loved how quick it was to plug and play, and while the tracker ball took a little getting used to, considering I had only used the movable kind of mouse before, I found it fairly intuitive and easily adapted to using it. This mouse has customizable buttons on it, that I was able to set things to for playing MMOs, It was quick and dependable for letting me get high scores on flash games. I am an artist, and one day my Wacom tablet broke, and I just.... used the mouse. Because of the smoothness of the tracker ball, I was able to draw with it and get the lines smooth and right where I wanted them. After a year or so, the mouse stopped working! I was confused at first, and then I remembered the battery! I pulled out the battery and swapped out for another AA, and it was right back to how it was before! Darn, no sparkly tempting blue orb for me. This mouse outlasted my computer, another computer, countless laptops, and is now on another desktop.... All easy swaps of the little dongle, and no fuss. This mouse started out being plugged into a computer with XP, then was moved to one with Vista, then Windows 7, then landed on Windows 10. I've used it for art, for regular computer things, for gaming, all sorts of things... All waiting to play with the blue orb of temptation. Every year or so I would need to replace the battery, and each time I was hopeful that the thing had FINALLY worn out... I would pull it apart, use a screwdriver to clear out pet hair, whatever fluff had gotten in the sensors, put it back together, add a fresh battery, and it was always as good as new. I can't tell you how many times it's been dropped, flat out thrown (I have three kids, who are super destructive) I've moved a couple of times, got married, had kids my life is COMPLETELY DIFFERENT than when I bought this thing. At one point a hot glue gun had been set on it before it was cool, and it had MELTED a hole through the plastic... but everything still worked 100% fine. I've pretty much given up on this thing EVER giving out on me. I figure it will outlive me at this point. Aliens in 10,000 years will excavate the earth, find this stupid mouse, with its a shiny blue orb of temptation, plug in the dongle (that magically will fit their systems), and start using the mouse to navigate their space ship. So this fall, when the mouse stops working, I'm like "When was the last time I changed the battery? I don't remember. Guess it's time to do that again (I've said a year, but in truth it depends, and I've gotten anywhere from 10 months to 18 months on a battery). I pull it apart, unscrew the case, clean all the components and sensors, put it back together, put a fresh battery in, and... IT DOESN'T WORK. I'm shocked at first. I assume there's something wrong with the battery. I try a new fresh battery, and it STILL doesn't work. At this point, I check to make sure I didn't mess something up putting it back together because I don't believe it's given out. It's been THIRTEEN YEARS with this thing not having issues... THIRTEEN YEARS!!! Literally teared up and felt bad throwing this away (minus the shiny orb of temptation of course). I pop on Amazon and order a new one, the exact same thing. So far this one is exactly as good and easy to use as the old one, and I figure in 13 years or so I'll probably order a third.

I've been using the predecessor to this trackball. It had a red ball & a tethered USB unit so the trackball itself could be wireless. It started eating up AA batteries faster & faster. When I was replacing them every couple weeks & having to create a new "handshake" between the trackball & the tethtered unit (almost daily), I decided to replace it. These units last a long time, but eventually they'll die (by "long time," I mean about 8-10 years). I read the reviews of this unit before buying to be sure their quality hadn't slipped, and I was momentarily hesitant when I read a review that said the ball didn't move as smoothly in this one as it did with prior models. I opted to take a chance anyway, and I'm glad I did. First off, the unit is identical in size to my previous model, so the comfort level was there. The ball was, indeed, stiff when I first got it out of the box. However, after about 5 mins. of use, it glided smoothly and effortlessly -- just like the one I'd been using for so many years. I'm a writer, but I also work in Photoshop and alter photos...sometimes, working on some very fine details. I've had no issues using the new trackball for those jobs. The biggest change between this trackball and my previous model is that this does not have a tethtered USB unit. It has a tiny little USB plug that slips into my laptop and that's all. Logitech has made it easier for me to move from my desk to the sofa to just about any other place by not having that tethered wireless unit hanging from a USB port. One of the best parts of using Logitech is my experience with their customer service. About 15 years ago, I had a different Logitech trackball (the ball was on top & moved by multiple fingers instead of a thumb ball), and it was not performing reliably (it was not wireless). I called their customer service department, and they shipped me a replacement trackball based solely on the serial number of the trackball that was defective. I didn't have to show them a receipt or jump through a bunch of hoops. The person on the phone was quite honest. He said that their units were now being made in China, and the quality control may have slipped when building the unit I had. It was refreshing to hear some genunine honesty from a company that had shipped their production overseas. Anyway, I'm a loyal Logitech user because they support their products, they perform as advertised and they're very easy to set up. The previous wireless trackball I owned came with a CD to upload the software. This did not. I had to go to the Logitech site to download the software. That's not a problem, but I thought I would mention it to cover all bases. I don't know how this works on a Windows computer. I use a MacBook Pro (latest model), and my previous Logitech trackball had been hooked up to an older wedge-shaped iMac, a new flat-screen iMac and now my laptop. The trackball worked flawlessly with all of them. When the time comes to replace this computer in a few years, I fully expect that this trackball will still be functioning properly and will easily transfer to the new computer.

I've had at least four of these (maybe six). The left mouse button always goes bad eventually. I suspect that people who dispute this either don't click a lot, or don't use the mouse all that much. If you mainly just browse the internet and read your email, this mouse might last forever for you. Because this mouse it popular with gamers, some users do a *lot* of clicking. In my case, it's programming and Freecell, which means a lot of both clicking and dragging. If you click enough, the left mouse will start to double-click when you single click. You might not notice it if you're just typing text, but it will show up very fast in computer card came like Freecell where a spurious double-click has dramatic and unpleasant results. It also becomes almost impossible to highlight text, because the button won't stay down. These are the same symptom, really. When you press the button down, it will alternately click and unclick because the top of the switch under the button is dented, and though the button is down, the switch may or may not be at any given moment. So, why five stars? Because this is, ergonomically, the best mouse on the planet, it's very reasonably priced, and it has a three-year warranty. Seriously, you need to at least try this mouse. Once, in a period of extreme boredom, I used this mouse to play Freecell for seven straight hours. No discomfort, no carpal tunnel, no ill effects at all as far as my wrist and hand were concerned. I have the mouse sensitivity set at its max. It takes a little getting used to, but I can move the mouse from the beginning to the end of this paragraph by moving my thumb less than half an inch. This makes highlighting text a dream once you get used to it. I use a keyboard drawer under my desk because it keeps me from aggravating my elbow and shoulder. That means the mouse goes on the little pull-out table on the right side of the drawer. When I used a conventional mouse. It kept either making me bang my hand against the keyboard on the left, or falling off the right side of the pad. This mouse never moves. When I reach for it, it's always exactly where I expect it to be. As for the button trouble. I have not had any luck getting the mouse apart to try modifying the microswitch. And you can forget about the solutions suggested by Logitech. If they work, it's only for ten minutes or so. However: I just read a comment here from someone who fixed the problem by putting a piece of note card stock under the left button. It fixed the problem but, understandably, made the button difficult to click. I just tried fixing it with a piece of very thin paper from a cash-register receipt. It worked! The button is a tiny bit harder to press, but it's still pretty sensitive. If the fix doesn't last, I'll just shell out the money for a new one. I often buy two at a time so I'll have a spare to use when the button goes bad -- this is handy when you have to get it replaced under the three-year warranty. Seriously, give this thing a try.

This is way, way better than a standard mouse. And this is coming from someone who for years refused to even touch a trackball, because "it wasn't a mouse." I'm not going to lie. A trackball will feel a bit odd after years and years of mouse usage. You'll want to move the entire unit around, only to realize that that's not how it works. Think of a trackball as an inverted mouse... The underlying mouse ball (remember those?) moves, while everything else stays stationary. That's how this trackball works. It's designed so your thumb comfortably rests on the ball, and your other fingers rest on the two buttons. Once you get used to this behavior, and it only takes a few minutes, there is no going back to a standard mouse. Ergonomically, I find the trackball so much better. It's stationary, so your hand isn't moving around as much, and the trackball itself is very precise. You can spin it quickly and fly your cursor across the screen, or you can move it very slowly and have slow, predictable movement. Once you use this, you'll realize just how much you have to move your mouse around to get the cursor anywhere, and it really bugs your wrist after a while. This particular model, the M570, is great. I have one for my Mac and one for my PC. They're inexpensive, the battery lasts forever (seriously, it's been a year and the battery life is still around 80%), they make use of the wireless Unifying receiver, so you just plug it into any USB port and forget it's there. And it uses laser tracking, as opposed to the optical tracking of the older models. So, yeah... I love this product. It's obviously not going to win any awards for features, but frankly, it does everything I need it to do. Scrolling, clicking, double-clicking, middle-clicking, and back and forwards buttons. The only thing I would like is for the scroll wheel to move horizontally, like some other Logitech mice can do, but rarely am I horizontally scrolling anyway. If you have even a slight interest in trackballs, give this a try.

Update 7/14/2019: Switches have started throwing multiple clicks when just clicking once or drops out when trying to highlight something. The usual problem for the M570 mouse. I now have about half dozen of these with bad switches. If you buy this then figure about every six months to a year and a half you will need to replace it. Will I be buying this model again? Maybe. For me it's the most comfortable and easy to use mouse that I have ever used. It's just such a shame Logitech uses such flimsy switches. I have several devices that I use track ball type of mouse and if these lasted longer I would have bought one of these for each device. As is the other devices get used seldom so I bought a more reliable wired track ball type mouse that isn't made by Logitech for them and use this M570 mouse only on the computer that I use for online gaming. Hear that Logitech? You could have made six sales instead of one sale if your switches were reliable. Just think how many people don't buy because of the crappy switches and how many more sales you could make if the switches were reliable. Isn't it about time you found better switches for this mouse? People have been complaining about the switch problem for years, so far Logitech hasn't done anything about it so you know they don't care about reliability. Logitech did replace one of those six M570 with a warranty replacement but that was after I had contacted them about buying a bag of the switches so I could replace them myself, they wouldn't sell the switches. So even there you can see they really don't care about customer care. There are other brands of track balls that are more reliable but have a different design and not use a thumb trackball. I have one of those since October 2013 and it's still working like new but with the Kensington ball using the palm for the ball movement I don't find it as comfortable. And there are lot more thumb style track balls on the market now so Logitech now has competition, check those options as well before deciding. I think I'll try out something from their competition and see if better. Also Logitech has a new wireless trackball called: Logitech MX Ergo Wireless Trackball Mouse. From a review for it: "It claims to use higher quality micro-switches than the M570, which are now guaranteed for 10,000,000 clicks compared to the 100,000 guarantee from the M570". But the price is much higher, on Amazon: List Price: $99.99 but current price is: Price: $77.62 Update 1/20/2018: bought a new one of this on February 6, 2017 and once again switches going bad, time for replacement again. Lasted almost a year this time. update 7/27/2015: About a year ago I asked Logitech if I could purchase a bag of switches for mouse buttons so I could replace switches myself (they wouldn't) but was kind enough to send a replacement as that one was still under warranty, well replacement is throwing double clicks and dropping out when trying to highlight or move anything.... time for a replacement. Such as shame they use such crappy switches on what would otherwise be a great mouse. You have to figure you will need to replace it every year or less. update 9/17/2013: both buttons have started to throw double clicks with the right button within the last month or two and the left button this week. This is a great mouse except for the button problems. Logitech needs to do something to increase the longevity of the buttons, shouldn't have to be replacing it in 6 months of moderate usage. Everything else still works great, just crappy buttons. I will have to look into replacing the buttons with better buttons that will last longer myself (maybe buttons from a keyboard?) or look for a replacement mouse somewhere else. I really liked this design and would hate to go back to using a mouse pad type of mouse, which really wouldn't work well for me. I like to recline in my comfortable chair with the keyboard on my lap and mouse on my leg. I have my monitor attached to a multi-jointed swing arm that's attached to a small roll about stand that holds my computer. I can sit in my chair and swing the monitor to in front of me.... but there is no place for a mouse pad... I would hate to have to go back to sitting at a table or desk to use my computer just because of the mouse... ______________________________________________________________________________________________ bought one Jan 2011, best mouse/Trackball i've used. Use to have the wired version but seems isn't available any longer, so bought the wireless version. Works as well as a wired mouse, never had second thoughts about having bought this wireless mouse. Now 2 years later it has been giving me double or more clicks with left button when clicking just once for several months now. Seems to be getting worse and doing double clicks more often... almost constant. Other then that mouse still works great. Will be replacing it with a new M570 Trackball. I seldom work at a desk and when I do there isn't much room for a regular mouse and mouse pad. With this I have both keyboard and mouse on my lap, never need a desk. After I get a new one I will take this one apart and see what can be done to fix problem, perhaps use it for parts for the new one in future.

Love this mouse. Helps with my carpet tuned no more wrist hurting and you dont have to move mouse ever just your thumb....

Hi I had 2 logitech trackballs in the past 9 or 10 years. It seems one of the minor complaints are that the blue ball isn't as smooth as the old Red Ball. Well I still have one Red Ball from one of my old Trackballs that broke and will test it with this new version and report back. Hey the red ball might not even work but I don't see why it shouldn't work..who knows . When I take delivery I will report back with an update . :) Edit: Well my trackball arrived today. Firs off it's much smaller than the old redball version. I wanted to test the red ball in this one but it won't fit so that's out. I'm a woman so I don't have big hands but I don't have tiny hands. That being said it fits my hand perfect. If you have big hands you might not like the fit but that shouldn't stop you if you are currently using a mouse which is smaller than the trackball. Yes the new blue ball doesn't have that slick feel that the redball had but it's still slick. You can tell the difference between the 2 if you used/owned the redball version.The blue ball is much smaller than the red ball but it doesn't hurt performance. I plugged the unifyer into the usb port and windows installed the correct driver in seconds. By the way I have Windows 7 64 and I was up and running right away..so yes no problems with windows 7 /64 for those of you that might be wondering. The 2 extra buttons on the side are programmed to go back and forward which is what I already intended to use them for anyway. Someone said the location of the 2 buttons was bad but I don't see the problem .Even if your index finger (Which is used for 1 click)were to brush up against the side buttons nothing would happen becasue they are sturdy enough for side swipes to not activate causing you to go backward or forward. And of course the scroll wheel which works as intended. This is without installing the software. There's no software DVD but you can get it directly from Logitechs website if you choose. One thing I don't care for much is the blueball location which is for thumb use. I like the old version where you used your index finger.It's just easier to control with the index finger than the thumb . It's not a biggie no no and there's no problem controlling the blue ball but I rather myself using the index finger. It already comes with a battery (Only needs one) and a duracell to boot. There's 4 rubber feet on the bottom which hide the screws so I'm guessing it should be easy to clean if need to when you run out of warranty. What I'm really pissed about is the price..I ordered this 2 days ago and now the price is much cheaper. I'm going to email them to see if I can get credit...hey it's like $10 with shipping..even the shipping was more 2 days ago. Big plus no freaking long wire hanging off the side of my laptop ! Bottom line I'm happy again :) PS:This vendor doesn't respond to emails..a simple yes or no was required of them but I guess customer service doesn't mean anything to them. ---------------------------------------------------- Edit: Nov 8th 2010 This vendor never did reply to my request mentioned above. Again a simple yes or no would have suffice. ---------------------------------------------------- Edit : Nov 11th 2012. Still working and I have dropped it many times where the battery cover and battery and ball were scattered all over and the handset itself took a nice bang when dropped. Each time I thought it was the end but nope she's still chugging along. PS: Still haven't heard back from the vendor 2 years later..LOL -------------------------------------------------------------------------- Update: 8/10/13 Still working like a champ and very surprised ,considering how many times I dropped this thing on my wood floor.

This is my first trackball mouse, and I really like it. I love that it just sits in one spot and I don't have to worry about it sliding around and moving on the screen. I have it hooked up to my desktop, which is hooked up to the TV about 10 feet away. The responsiveness is great, no lag. It does take a little bit to get used to the trackball, and maybe adjusting the responsiveness, but I think it's worth it. The feel is great, and I love the extra side buttons. Overall it's well designed and functions perfectly. 2016 UPDATE: I've had this mouse for over a year now, and it's still my favorite. It's become my main mouse to use with my laptop at home. In fact, I'm going back to buy a second one for my work computer. It's great that it's stationary, so it doesn't need as much room as a regular mouse. I also have less strain on my wrists, since I don't need to move it around. I don't think I've needed to change the battery yet, because I literally just realized that the light on top is a battery indicator. Every once in a while (depending on where I'm using the mouse), it will get resistant or skippy - that just means it needs to be cleaned. Pop out the ball, clean the lint off the 3 sensor points, and pop the ball back in! That always fixes any responsiveness issues I face. I will say (for when others use your computer) those who are not used to this mouse will either love it or hate it. As I stated, earlier, there's a learning curve, and people who didn't sign up for it won't like that curve. Almost everyone who uses my mouse is super annoyed by it...I think one person loved it and wants to get her own, understanding that it's great once you're used to the trackball. But everyone else is quite confused by why I would want it... So really the only negative is other people's reactions to being forced to use it with my computer. 2020 UPDATE: The original mouse I bought finally kicked the bucket mid-2019, which was about 4 years after purchase. Its responsiveness was going downhill, mainly having issues with the left click. So I replaced it with the same thing, no regrets. I have one at work, and one at home, both for laptops. I will likely be purchasing a third one this year when I buy a gaming desktop. Basically I'm just to the point where every computer I own needs this mouse. Now that I have more than one of these, there's the real potential to mix them up (also a problem with owning multiple of any Logitech mouse receivers, cause those guys look the same even if the mouses don't). What I do to avoid any issues on that front, is put a drop of nail polish on the mouse and the receiver, so they match, and I know if I have the right ones together. (Ex- Found a receiver with a drop of holo green nail polish? I know my work computer's mouse has a green drop, so I must have left it at home and need to take it back to the office. Problem solved.) As long as the polish is put somewhere you don't touch much (or at all), it'll last a long time.
