Logitech MX620 Cordless Laser Mouse (Black)

I love this mouse, it uses "fast RF" technology, not Bluetooth, to connect to a small USB receiver. The scroll wheel has adjustable firmness, which allows you to either scroll through a couple lines at a time, or through many pages in seconds. The laser for this mouse is invisible, which is good for people who hate the bright red LEDs of optical mice. The mouse worked instantly when connected to my PC running Windows Vista. Optional software can be installed from Logitech to take advantage of various customization choices (button assignments, on-screen battery indicator, etc.). A button on the bottom can be used to turn off the mouse when not in use to conserve battery life. Logitech states the batteries will last for 1 year, and two Duracell AA batteries were included in the package. Nice. A battery indicator LED on the mouse shows when it's time to swap out those cells, which I haven't had to do yet after one month of ownership. I bought this mouse to replace a Microsoft Blutooth mouse that was part of the "MS Optical Desktop Elite for Bluetooth" which was ALWAYS dropping its connection and for which I had to recharge NiMH batteries every few weeks. This mouse was worth every penny, I would highly recommend it to right-handers looking for a simple, elegant mouse that will provide them with many years of happy mousing. EDIT: Here I am in the beginning of September, and the low battery light finally came on! These batteries have been in constant use (maybe 5 hours+ per day) since December 2008. The battery level states that I have 30 days left to replace the AA batteries.

This is one of the best mice I have found to work well on Mac. I've been using Mac now for several years after being a lifelong Windows user. I had been using the Apple bluetooth wireless mice and in general I liked them, but after a while they would start acting up. It would become very difficult to right-click or the scroll ball would get dirty and start sticking. The dirty scroll ball is easy to fix (just clean it) but the right-click issue would really become a problem. I ended up going through probably 4 or 5 of these mice before I decided to ditch it and try something else. I then did some research online and ended up buying quite a few more mice. The first was a Microsoft bluetooth mouse. It took a bit of "hacking" to get it working on Mac but eventually it paired up but I didn't like the performance at all. It was very laggy and unprecise. After more research, I then ordered the bluetooth mouse from Razer. Razer is very well known as the makers of some of the best mice for gaming. Very precise and accurate. But, they are a bit expensive. I ended up ordering two of these based on the great reviews (one for my Mac Pro and one for my laptop). These turned out to indeed be very precise and accurate but they had an irritating trait. If you let it sit still for just a couple seconds (and I mean only 2 or 3 here), when i went to move it again it would have a slight delay in responding and thus the mouse pointer would end up jumping. I found this extremely annoying and made it very difficult to use. I contacted Razer about this and after a few email exchanges and testing on different computers (I tried on a total of 6 different Macs all with the same experience), they told me this was due to it going into a "power saving" mode to make the batteries last longer. I told them this was ridiculous and this should only happen maybe after a couple minutes of sitting still. Not just a couple seconds. They told me they'd bring this up with their engineers. I then decided to give up on bluetooth as nobody seems to make bluetooth mouse that responds well with the exception of Apple but their mice have different issues. So, I then tried a Microsoft wireless mouse that uses a USB dongle instead of bluetooh for wireless communication. This mouse turned out to also have bad delay problems. So, finally I decided to give Logitech a try and ordered this mouse (MX620) from Amazon. The same day I also ended up going to a local big box store and picked up the Logitech VX Revolution Cordless Laser Mouse for Notebooks as it was on sale. The VX Revolution is very similar to this mouse but it is marketed as a "notebook" mouse and is thus a bit smaller. I figured I'd use the VX for my laptop. So, I tried them both. First I tried this mouse from Amazon and it worked great! Very responsive and accurate. No delays. No lag. It was just perfect. I was so relieved to have finally found a decent Mac mouse! I then decided to try the VX Revolution and it worked just as well as this one (MX620). But, I liked it a bit better due to the "feet" on it. They are made out of some kind of very slippery material and it glided much smoother over my hard plastic Everglide mouse pad. The MX620 has feet that aren't quite as "slippery" and thus takes a bit more effort to get it to start moving. The result ended up being that the VX was better for making very small movements. So, I love both the MX620 and the VX Revolution mice. They are both excellent mice for Mac users out there. They also make an Logitech MX Revolution Cordless Laser Mouse which also sounds great (same slippery feet as the VX Revo but is a full size mouse). But, I didn't want to give it a try as it is rechargeable and thus requires a charging base to be on your desk and you have to remember to keep putting the mouse back in the charger. For me, I didn't want the extra desk clutter and yet another power brick to deal with. I'd rather have a mouse that uses normal batteries which these two mice do.

I have been experimenting with going over to a cordless mouse (Bluetooth and USB 2.4 Ghz) from a corded optical, but with unsatisfactory results. They seem to all have their quirkiness... I sent several of them back. They all claim precision but often are not so precise. I use a computer for my work practically 24/7, and great usable mouse is one that has the perfect balance of weight, gliding and user control. I find a good ol' $20 optical corded mouse more precise, more controllable, does what I want it do and go where I want it to go. On the plus side this mouse feels great right out of the box. On MAC OSX it took me just plugging in the USB 2.4 Ghz transmitter and the mouse was on and working. Feels great ergonomically in the hand and it feels like a corded mouse at first... But! The MX 620 is quite heavy which takes some getting used to. I think the four little stubs on the bottom of the mouse are inadequate to give it enough gliding for such a heavy mouse. I kept overshooting targets like links, files, windows and such because I had to give it a push to get it going initially and then I overshot the target... I tested this repeatedly and after a few days I just couldn't deal with it. One major disappointment so far is that the Logitech Control Center software on OSX does not support this mouse and therefore I can only use the left and right buttons and the scroll-wheel but have no access to or programmability for the other 5-6 functions of the mouse (as on Windows). It is clearly indicated on the support download page that they provide this software for this particular MX 620 mouse. Bad, bad, bad Logitech. It's advertised as Mac OSX compatible. I downloaded support software from the Logitech website only to find out that "no device is found" when I open the Control Center. Why is Logitech wasting my time? I not only had to download the software, install it and THEN restart my Mac, when I called Logitech's support phone number I was put on hold for a long time and then simply disconnected. Then I finally got someone on the line and had to unistall, re-install, restart several times to ultimately find out this software and mouse does not work on MAC OSX as advertised. (only with limited basic functionality.) Now that's what I call instilling trust in the customer and a "great customer experience!" The final verdict: I sent mine back due to the complete waste of my time Logitech put me through by claiming it to be MAC compatible. In my book that is false advertising. All the time I spent with buying this mouse and trying to make it work I could have bought another mouse, instead of waiting for my order to arrive, finding out why it doesn't work, calling Logitech Tech Support, spending precious time on the phone with a support guy only to find out after downloading and installing, uninstalling, re-installing and restarting numerous times that this mouse is just not for me. Going to get another corded one!

I wanted to like this mouse. I have tons of Logitech products from keyboards to mice to speakers to headsets and, while I have never before filed a service claim, they seem to be decent products. Until they break, that is. A set of fresh batteries lasted only a few weeks. The next replacement set (fresh, new premium batteries) the Logitech SetPoint software told me I could only expect about 92 days but each day I checked the estimate kept rapidly going down. I contacted Logitech and a rep named Benjamin R had me test a few things. He then had me uninstall the current SetPoint software and install a much older (and more limited) version. That didn't work. At that point he declared the mouse defective and offered to replace it. These are his broken-English words: "It seems that the mouse is begging to be faulty with losing battery life at a much higher rate. Kindly update this incident with your contact details to update our database This is to check and verify if our System Generated contact details are correct, and in order for us to proceed with your warranty replacement" I sent him everything he needed including 2 photographs and he refused to do anything more, citing that I didn't have an original receipt (Amazon only does packing slips as receipts) and he is under strict orders to require one. But nowhere when you purchase the item do they tell you that they won't honor their warranty without a hard copy of what they consider an receipt. Given time I might be able to find mine but he only gave me 168 hours (totally weird) to produce the receipt otherwise the case was closed. So let's say the mouse didn't fail and Logitech didn't refuse to do anything about it, how do I like it? The "in-hand" feel is nice. I like it except for some bad ergonomics. My thumb naturally seems to drape over the "forward" button rather than the more used "back" button on the side. The user-button next to the left-click button is too easy to press accidentally. The scroll wheel is user selectable to be either clicky or smooth scrolling. Clicky is too clicky and smooth isn't really smooth. It will often stall as I am vertically scrolling and refuse to budge. I use the mouse often for graphics and photo editing and find that it stutters when trying to move it in a straight line or make circles or squares. To be fair that is something more suitable to a graphics tablet but I have seen many mice much smoother than this one. It just appears that it forgets what it's doing and has to stop and think about it. Not a good thing for a mouse. If not for the bad customer service I would have probably rated this a 2-star. Why? Because it costs $90, a ridiculously high price for a computer mouse that is a mediocre performer. It drops to 1-star because of Logitech's poor customer support.

After having an excellent experience with the Logitech MX-1000 Laser, i next purchased the much-hyped MX-Revolution though i was a bit dubious about the sturdiness of it's "Micro-Gear" scroll wheel which switched between smooth and clicky modes via software or pressing it. The relevance of my experience with the MX-Revolution to the MX-620, is that the "hyperfast" scroll wheel on the 620 is essentially the same as that on the MX-Revolution, without the software control of mode switching. Being a Mac user, i had to download the "Logitech Control Center" software which is not included on the PC-only CD, despite Mac compatibility being specified on the box. The software was, and still is horrible. It was riddled with bugs, had a poor feature set, and crashed virtually every time i tried to change settings. There followed a completely unproductive 2 weeks of haggling with Logitech's (non)support department. I thought i was going to be okay once i switched to a 3rd party driver, though i had to sacrifice the "auto-switching". Unfortunately, my worries were justified. The fancy scroll-wheel broke down after just a couple month's use and i returned the Revolution, replacing it with another MX-1000. When the battery on that mouse began failing to charge after a couple months, Logitech replaced it... with another MX-Revolution. I sold it. Though loath to take another chance with Logitech, i was unable to find any mice comparable to Logitech's for comfort and number of buttons, I decided on the MX-620 because it was cheaper (not being rechargeable) and because i was fairly certain i could avoid using LCC, which has made little improvement through the 3 or 4 recent updates. I was really loving the 620 (used with SteerMouse) for a couple months. The fast scroll wheel can be very useful and the life of ordinary AA batteries is phenomenal on this mouse! I haven't changed them yet, whereas past alkaline powered mice i've had gobbled them in about 3 weeks or less. However, over a recent period of just a couple days, the "hyperfast" scroll wheel began to require more and more force to make it coast. Refusing to buy a 4th mouse in less than 10 months, or deal with Logitech support, i've continued using it. However, the scroll wheel now requires significant force just to roll at ANY speed. The small rubber strip down the center of the wheel which gives one's finger traction, has slowly become more and more stretched and seems to be interfering with the wheel's spin somewhere underneath. This will definitely be my LAST Logitech mouse unless they make serious improvements to their Mac OS compatibility, their customer support, and the durability of their hardware. These snazzy innovative gizmos aren't worth the premium price if they're only going to last 2 or 3 months!

I've always liked the form factor of Logitech mice, so I was going to buy a Logitech mouse; I just wasn't sure which one. Since this mouse was going to be for work, I didn't want to spend an arm and a leg on it, and I didn't need too many bells and whistles. I wanted a good sturdy wireless mouse with a long battery life and two thumb buttons. This mouse delivers in all of those areas. The MX620 has the same great fit in my hand that I've come to know and love from Logitech mice I've purchased in years past. It's built sturdily, and the batteries help give it the nice weight that's light enough not to strain my wrist but heavy enough not to float around at the slightest touch. All of the buttons are programmable, which is good for me, since I don't have much use for a "search" button next to the left click. The hyper-scroll wheel is an excellent concept, but the execution could be slightly better - it takes a bit of getting used to. Fortunately, if you don't like the free wheel, you can always just flip the switch on the underside and it'll act like a "normal" scroll wheel. It's a wireless mouse, so if you game with it, you'll notice that after not moving for a certain amount of time, there's a (barely noticeable) response time - this is true with all wireless mice (it's a battery-saving feature) but with this one, it's a lot less noticeable than with others I've used. Overall, it's an excellent mouse that I use without even thinking about - at a price I hardly had to think about too. Pros: + Sturdy build; solid buttons let you know when you've clicked them + Hyper-scroll wheel with switchable mousewheel mode + Excellent design, feels great in my hand + Never have to think about its movement - it just works + Battery life is excellent Potential Cons: - Some may not like the free scroll wheel - sometimes a little too "free" - Wireless mice aren't great for gaming due to wake-up time - (I actually can't think of any other potential cons!)

No regrets on this purchase, have a had it a couple weeks after upgrading from a wired, optic mouse. I have Windows Vista and so far no problems with connectivity or access to the mouses functions. I think it's important to note that I actually went to a store that carried most of the mice I was interested in and was able to test them all out for overall performance, quality, comfort etc... this allowed me to actually feel what I was going to purchase (a concept some people don't seem to understand, why buy a mouse online with no idea of how it actually feels for you personally). After trying the different mice I narrowed it down to Logitechs and eventually I decided to go with the mx620 over the revolution. Both felt very comfortable, but I actually found the 620 to be more comfortable overall (for me personally). Although the 620 doesn't have the rechargeable battery, thumb wheel, or the neat auto-shifting wheel gear of the mx revolution it does hold a charge for a much longer period of time (lower maintenance), it has thumb buttons that can serve a similar purpose to the wheel, and so far I still prefer the click to click style thumb-wheel anyway, as I personally am rarely scrolling through massive documents. Also, for me personally, if I am worried about work-flow and speed I'm usually using my wacom tablet instead of a mouse. Tablets allow for much faster point and click or ink and paint as well as giving the user a much more fine touch in general, they just take a while to master. This fact made the extra functions on the mx revolution less appealing to me. As far as other complaints on this mouse from previous reviews I would say what I said before; go to the store, try out some mice (or anything else that requires constant interaction for that matter), and talk to a knowledgeable sales clerk about any possible downsides, such as problems with a certain OS. This should make your decision much more obvious in general. Laser will feel different than optic also, it took me a while to get used to it, but now I prefer the laser. I will say, however, that this mouse might not be for everyone. As with any mice that are different from what you previously used, it will take some getting used to. After using optic for so long the reaction times felt odd with the laser mouse, but after a week or so I came to prefer it. The thumb wheel's click to click function has much less resistance than your typical mouse. Once again, this felt odd at first but I now prefer it's smoothness and it feels like it strains my hand/wrist less. It allows me to scroll faster when I want, just takes more of a fine touch for slow, accurate scrolling than what I was used to. The little search button to the left of the left mouse button is kind of silly (though i found it makes a handy quick spell checker if you have a fast enough connection. just highlight the word in question then click with the little search button and your search engine will let you know if you miss-spelled it or not), but you can reset it to many different useful functions so who cares? Bottom line >>> Good mouse for the price. I use it much more for general computer use and for programs like photoshop, aftereffects, video editing, and maya than i do for gaming, but it still works just fine for casual the casual gamer. Each button (except standard left and right) is reprogrammable and the logitech software allows for fine tuning of speeds, acceleration, etc. This mouse also had the weight, balance, comfort/ergonomics that I was looking for. I repeat; I only knew this buy going and trying them out for myself. There is no one mouse to rule them all, as everyone has different shape and size hands/wrists/fingers as well as different personal needs. So go out and try it on before you buy (just don't let the sales people at the store know that you don't plan on actually buying from them, duh).

I've always been a fan of Logitech products, and this one is no different. The MX620 is a very well-constructed product with buttons in all the right places. The mouse fits my hand perfectly and is spectacular for long-term use. I use it for such detailed tasks as 3d rendering, and it's also an excellent gaming mouse. The battery life seems to be quite good, and there is no sluggishness in the responses at all that I've been able to tell. What an excellent mouse for the money. It's not as large and complex as some of the more specific "gaming" mice, but it fits the hand perfectly and does everything it should.
