M7-3 color LCD model

Recently picked up a new to me older truck that's super bare bones, xl version 2010 ford ranger. My old truck has tpms built into the dash menus, so I like to keep up with the tire pressures as I drive about 60 miles round trip a day. The little sensors screw directly on to the valve stems like caps and tighten down nicely, I don't think they'll ever fall off accidentally. Easy to install and set up. I use a 4 tire hose that fills them all at once, so I know the pressure is exactly the same in all 4 at all times. When I first calibrated the unit they all showed exactly the same psi. Once the sun came up next day, I noticed the pressure and temps were higher on the side in the sunlight, so they're remarkably accurate. Driving at highway speeds, the pressures go up about 5psi by the time I get to work. First day driving it I was hyper sensitive to all the new to me noises and road sounds, and was very surprised to see the tire pressure light come on the dash. Apparently it's got super basic pressure senders in the wheels I was unaware of, and it was not happy at the 25 mile mark. I had my trusty new tpms system installed so I immediately stopped and checked it, pressures and temps all looked good, so I assume the factory sensors need recalibrated or one is damaged or missing. If I hadn't had these installed, I would have been panicked and stopped to check all 4 with a gauge manually. This way I'm able to glance at it and know exactly what's going on in real time, even without stopping. Great for peace of mind. It's got a rechargeable battery inside you can plug in via usbc or leave it in the sun and a little solar panel on top will charge it. I only every drive at night (midnite shift) so I opted to not mount it on the dash, as I think the bright lights it puts out would be distracting. I mounted on the drivers side wall inside the center arm rest. Easy to see from the drivers seat, but pitch black in the dark cockpit, also easy to reach with a usbc cable to charge, although a month in and the battery still shows good charge even leaving it on 24/7. The alarm when a tire gets too high or low is very loud, even inside the arm rest it startled me when one went up higher than expected at highway temps. Overall, I'm super impressed. Has all the features I want and none I don't. Price is great, shipped quickly, seems to work perfectly. I still have to figure out the factory tpms issues as the light still comes on at 25 miles, even tho the pressures are spot on. But with this new system installed, I'll never have to worry about what does that light mean?!!?!? haha. Great purchase, buy with confidence.

Talk about easy. Just screw the transmitters on the tires as directed, charge the receiver and set it on your dash. Bingo, you're seeing each tires temperature and pressure as you go. Easy, peasy. Love it!

Replaced the monitor I left on the bed of the truck while traveling. This product is great...been using it for 2 1/2 years. Very reliable with the peace of mind RVing full time. Easy to install...syncs right up to the monitor. Great instruction. I recommend this for anyone traveling full time.

Just installed it today. It was an easy install. The only thing I may have a problem with is the small display. I don’t think I will be watching it much. I will be depending on the low air alarm which I tested. System has a great audible sound.

This is so good! I held off on installing this for a year because I didn't know anything about cars and was intimidated about the idea of using this . About 3 months ago, I finally wised up and looked at the instructions and did it. It was embarrassingly easy! I validated the pressure against 2 different well-regarded pressure gauges. Anyhow, today, 3 months later, it's going off with a piercing alarm and showing what seemed to be impossible PSI decreases. Well, it was not impossible lol . I have an EV so my car is extra heavy. I pulled off to a safe spot and a tire tech showed me where a nail used to be embedded in my tire (and had dislodged itself). This has been a wonderful purchase and I'll never be without. Next up, I'll learn how to patch my own tire - baby steps, though. Baby steps.

This is a great alternative to overpriced factory tpms options. Sensors seem very accurate within 1-2psi. Easy setup in a couple minutes and wireless is a nice touch. Takes a minute for the unit to read the sensors when turned on but not bad. Anti slip pad works great on dashboard. Unit is smaller than expected which is a plus. It is discreet and fits anywhere. The screen is dim and very hard to see in direct sunlight but I dont need to see it constantly anyway. It notifies of sudden pressure loss and that is mainly what I needed. Already saved me a few times with a blowout. Solar works well. I have never seen the battery level go down since ive owned it. Anyone giving bad reviews is expecting too much from a system that is priced so low. Seems like people want the capability of a $300+ system and thats just unreasonable.

I bought this a few weeks ago for my single axle 3200 pound popup tent trailer. I'm so glad I did. I have towed this trailer at least 20,000 miles, and never had a tire problem. The tires still look good, too. But out of precaution I bought this sensor kit and installed two of the sensors on my trailer's wheels. Then over the weekend I set out on a 600 mile round trip camping trip. On the way home, in the middle of nowhere other than a busy interstate, the sensor started sounding the alarm. My right trailer tire dropped from 70 PSI (warm, driving pressure -- 65 cold) to 60 in about a minute. For a moment I doubted, but then it was 55 and dropping. I found the nearest exit a mile down the road, and pulled safely off the highway. Within another couple of minutes the tire was down into the 30s, then the 20s, and by the time I had a jack under the tire, it was flat. I was able to install the spare and make it safely home. Now consider what would have happened without the sensor; the tire would still have failed, but as it got closer and closer to empty, it would have overheated and shredded at 70 MPH on a busy highway with no warning. We could have become a road safety statistic. The thing people don't often realize is that you really can't *feel* when a trailer tire is going flat. A 3200 pound trailer being pulled behind a big pickup truck just won't give any feedback until it's too late, at which point you find yourself trying to avoid a terrible accident. Okay, about the product: Four sensors that work great. They seem to update the display unit about every 20 or 30 seconds. The display shows the tire's temperature and its pressure. You'll see both temperature and pressure rise as you put a few miles on the tire, and then stabilize. The display shows this happening, which is totally normal. But if suddenly one of your tires gets too hot, or loses pressure (either slowly or immediately), the alarm will sound, and hopefully you'll have enough time to get off the road before there's a total failure. In my case this device saved me the very first time I used it. And it saved me from potentially hundreds or thousands of dollars of repair costs. I had a friend blow a tire on their single-axle trailer a couple years ago, and while they were able to get off the road, the blowout tore the fender right off their trailer. By observing the tire temperature and pressure, you can avoid those sorts of situations. I really like that it is solar powered. I know that seems like a weird feature but think about it; you set the display unit on your dashboard, and it will be in near constant sunlight during the day. No need to worry about another USB cable to keep it going.

Amazing little unit. Opened the package, read the instructions, and installed it without any hassle whatsoever. The unit makes an very audible beeping sound when you hold the power button down for about 3 seconds. The battery indicated an almost full charge, and was fully charged after being plugged into my laptop for about 15 minutes. I took the unit out to my car, then swapped out each valve cap for the clearly marked one with the sending units in the kit. You'll hear a slight hissing sound as each sending unit goes on, but it goes away once it is tightened firmly. Also, the sending units look a little bulky, but they weigh about the same as the stainless steel caps I had on it.

So good so far . But like most things today give it a few weeks and it could be a different story.

Might be ok for a small rig, but with my 5th wheel and the distance at 30 feet it wont read anything. Not sure what this is made for but save your money
