Tire Pressure Monitoring System, TPMS Tire Pressure Monitor System Solar Waterproof TPMS Sensors Set of 4 Wireless LCD Display Tire Pressure Monitor Real-time Detection for 0-87 PSI Rv Trailer

Been using for 3 months and everything is doing good. I plugged one of my tires and instead of having to manually check the air pressure I bought this device. It's easy to install and battery is still going 3 months later. The device will go down by one bar after sitting in a garage overnight but after driving in the sun for a couple of hours it'll go back to 100%. It's pretty accurate as far as I can tell.A con is that it's kind of hard to uninstall out of the air plug. You need the special tool they provide so you can tighten and loosen the plug. It would be bad if you loose the special tool because you can't loosen it without it. (Disclaimer: it's hard to uninstall if you install the locking nut, otherwise if you don't install that it's simple to take off)

Simple install and all worked initially. Accurately, too. But a couple months in, one of the sensors stopped sending a signal. Tried replacing the battery, but that didn’t work either, and it also ripped the o ring seal when trying to put it back together.

We used these on our 26 ft travel trailer RV. Out of the box, these seemed to work great. But then reality hit. They would stop displaying pressure on random tires at random times, while we were towing! Then they would SHOW pressures when we were disconnected from the RV and miles away from it. And when connected and towing, the pressures would never change! (should have increased with tire temperature during the first hours of the drive). Completely unreliable. AVOID THESE. We returned these and bought the Tymate ones on Amazon - twice the price, but they work MUCH better (see my review there).

Keeping correct pressure is easily overlooked, but very important part of safety. This monitor does the job. 1 of the caps was off by 1.0-1.5 psi, but will get the job done. Caps are on the heavy side & it seems to affect the wheel balancing a little bit (if you have a lighter wheels this may be more noticeable). Read out is very clear and is visible even in direct sunlight. Slim profile allows good placement likely in most cars.
