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 soon 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.

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.

I'm very happy with this Tire Pressure Monitoring System. Seems to be pretty close on pressures on my utility trailer. Pressures were within 1 or2 pounds on what my gauge shows. I can't guarantee the gauge is accurate, but they were close to the same. I was concerned that the distance from the dash of my pickup where I have the monitor, to the trailer tires might be a problem, but no issues, it works great. After 3 month, I did have to replace 2 of the batteries on the wheel sensors, but there's no telling how old the batteries are that came with the TPMS. It did come with 2 extra batteries. They use, easy to find, CR1632 3V Lithium Battery, 1 per tire sensor. I can't say how long the batteries will last, time will tell. The 2 batteries I replaced, I purchased a fresh set, so we will see. Overall I'm very pleased. I will update if any issues arise.

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).

Works great it's too much work to take apart or put on when refilling tires

Funciona bien

My 18-year-old Mercedes has a retractable hardtop, so there is no space for a spare tire - not even a "donut". I don't have, or want, expensive run-flat tires, so every time I drive I run the risk of getting stranded if there's a problem. This wireless tire pressure kit is perfect - it continuously shows show me that all four tires are correctly inflated at all times, and will issue an audible warning if any tire's pressure drops below a preset alarm level. That will let me correct the problem before it becomes worse. I carry a small puncture-repair kit and a small 12-volt compressor, so this device will warn me about a leak in time to stop and repair it and re-inflate the tire before the tire gets ruined. I love this technology, and the price is an amazing bargain for what you get.

So these were working nicely until summer, and I guess the heat killed the sensors or the screen. I would change the battery and try to repair the sensors but I lost the very specific tool that you need to open them.

too layzee too poot on car.unda too muchy presser
