    • Set it and forget it—the auto-calibration and solar display are fantastic!
I picked this up to keep tabs on my tire pressures without having to manually check them with a hand gauge every single week. This Masoll system has been an absolute lifesaver. The best feature by far is the auto-calibration. Instead of standing there pressing a bunch of tiny buttons to manually program high and low warning thresholds, the monitor automatically sets your baseline when you screw the sensors on. It alerts you if a tire drops 15% lower or goes 25% higher than that point. It makes setup incredibly user-friendly. The solar display panel works perfectly sitting up on the dashboard. I haven't had to plug it into a USB cable once since the initial charge because the solar element keeps it topped off under daylight. The anti-reflective screen automatically adjusts brightness between day and night, making it easy to read in direct sunlight. The readings are fast and match my digital shop gauge perfectly within about 1 PSI. Highly recommend for the peace of mind. ... show more

    • Great value for the price
Easy to install. Worked well and provided accurate tire pressure and temp readings (verified with tire gauge and temperature sensor). Great value for the money.

    • Set It and Forget It: Solar TPMS That Stays Charged
Review Image by Roland
For anyone who wants to know when their tire pressure is low, this is the device for you. A few years ago, my original pressure sensors stopped working. I dealt with it for a while, but after getting new tires and trying to reuse my old sensors (which didn’t work), I needed a solution. I decided to give this unit a try, and I’m very pleased with it. It works as intended. I’ll be honest, I haven’t taken the time to learn all the features, but just being able to monitor my tire pressure is more than enough for me. One thing to be aware of is highway driving. After about an hour at higher speeds, the unit may start beeping as if the pressure is low. From what I’ve noticed, this seems to be due to increased tire temperatures at higher speeds, which can affect pressure readings. It might start with one tire and then move to others. Once you slow down or stop and return to normal driving, the system resets itself. One thing I really like is the windshield mounting with adhesive. It allows the solar panel to stay exposed, and even in low sun situations like overcast or rainy days, the unit still seems to pull in enough light to stay charged. After about four months of use, I haven’t had to charge it once with the USB cable. Installation was easy, but make sure you use all the included parts so the sensors stay secure and don’t walk off. Overall, a solid unit that does exactly what I need it to do. 👍 ... show more

    • Outstanding sensors
I’ll buy a set of these before I ever buy OEM tire sensors. Work so much better and gives real time pressure. The display is easy to see and I have it mounted next to my rearview mirror. Doesn’t stay on when your not driving so you don’t have to worry about it being on 24/7 draining batteries in the sensors. ... show more

    • Seemed to work very well
My tire dealer recommended a tire monitoring system for my RV. I didn’t know they existed. I picked this one for a couple reasons. The price was reasonable and had good ratings. I installed the valve stem caps (way too easy). I was pretty skeptical. It synced immediately. Ok, so far so good. I did notice that the readout wasn’t precise to what my tire pressure gauge read. But, a few pounds difference wasn’t a concern as long as they were consistent to each other. It seemed that they were. Over the next few days, I noticed that the pressure readout changed a little with temp change. They didn’t seem to be precisely consistent. Ok, so I guess we will see how it works. I left my home for a 3500 mile road trip. The readout was pretty easy to see attached to the windshield. I watched as the tires heated up and the tire pressure rose. I still didn’t really trust that it was working and tried to make sure I glanced at it regularly as I drove. After driving about 1000 miles I kind of forgot to keep a close eye on the display regularly. At about 3000 miles I suddenly heard a beeping alarm. I looked at my wife and said what heck is that? It took a few seconds for me to realize it was my tire monitoring system. I was very surprised, I didn’t realize it had an alarm. Sure enough, I was losing air in my right rear trailer tire. I was able to pull over and add some air so that I could get to my destination (a couple miles away). I was pretty impressed. Saved me a tire. A trailer tire that goes flat makes hash of a tire. I didn’t ever have to charge the thing after the initial charging as it is solar powered. It does come with a usb-c cable for charging if needed. I had charged it up before installing. I am considering buying a system for the boat trailer. I’ve had flats on that too. I wouldn’t really want to have 2 separate displays attached to the windshield of my truck. Maybe taking the valve stem caps off the trailer when using the boat? Haven’t decided on that yet. I was pretty happy with experience of using this system. ... show more

    • Not worth it for a travel trailer
The monitor connects easily to the the sensors on the tires and immediately registers correctly. But on the last 500 miles of my first 2000 mile trip with sensors on my travel trailer, they started registering low pressure. When I checked, the pressure was actually perfect. The repeated beeping was annoying. They are not worth it. It's just as easy to get a simple tire pressure gauge and check the tires once in a while. ... show more

Works great, easy set up except my rear right keeps thinking it’s on the spare and I can’t see it from the main screen. I am not too concerned because it should still alert. Great battery life, still gas 3 bars after a week in the center console
