Tire Pressure Monitoring System, TPMS for RV and Trailer, Solar Powered TPMS with LCD Display, 4 Sensors, Real-Time Pressure and Temperature Monitoring, Easy to Use (0~87 PSI)

I would buy again exactly as order and worked great!

This is a great product for the price, very light weight, very easy to install, compact size easy to find a place on dashboard, we used it on our business trailer for more then 2000 miles and no issues at all.

If you set it for PSI the temps read in degrees C, if you set it for Bars then you get temp in degrees F. I don't know if it's just mine, or a glitch in how they were made, or something I've missed in the sparse and microscopic instructions. According to the docs, and common sense, bars are paired with C and PSI with F, as logic would dictate. If there's a way to set these parameters separately, I haven't discovered it. No big thing, as I'm concerned about pressure, not temp. but something to consider if you are.An installation tip:You may need some WD-40 or Corrosion-X for the valve stem, as the lock nut needs to run further down the threads than the old cap covers and there may be a bunch of road crud. Having a 13mm socket would be good, as it's hard to get much leverage with the little included wrench. Be sure to hold the stem with a pliers, if it's necessary to really crank to the nut initially, to avoid excessively twisting and damaging the stem.As far as accuracy, I tested it against another digital gauge I have and the pressures matched. No evidence of leaks, so I guess it's so far, so good.I'd have been happier if it had been delivered on time, but I guess that's a different review.

After setting up the sensors the readings do not change at all and several times the reading drop off. Go back and calibrate them again but same thing happens. Need accurate readings for my RV tires and this product definitely doesn’t work.

Easy to use and does what it is meant to do

The TPMS doesn't seem to be as accurate as my last purchase from another manufacturer. It isn't a big concern for me since I use this system to monitor tire pressures on my golf cart and only care if the pressures become very low. If I used it on an RV trailers I would be more concerned. The readings seem to be 2 psi low and bounce around a bit. I compared the readings to a tire pressure gauge which has been calibrated. Although 2 psi low, I set the 4 tires to 20 psi and now 3 read 20 psi, but one reads 22 psi. I recheck again comparing readings from my vehicle which provide individual tire psi readings, the gauge and this TPMS to see what happens.

I installed this TPMS on my car, and it’s just awesome! It's very convenient that it runs on solar power, so I don’t have to worry about changing batteries. All the data about pressure and temperature is clearly displayed on the screen in real-time. The installation was easy, and the device is very user-friendly. Now I’m always confident that my tires are in good condition!

The first set received did not work right. It is very easy to get a replacement set through Amazon. The 2nd set has been working pretty well so far. I am quite satisfied and it's price seems to be pretty reasonable. I recommend it. But it's user manual is quite bad/useless.
