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

Affordable, stylish, solar-powered monitor for monitoring tire temps and pressures. Great feature add-on for older autos without TPMS. Easy to setup. Tire sensors screw onto valve stems, Easy change sendor battery lasts 1 year plus

I received the tire pressure monitoring system quickly. It is a little bigger than the ones Im used to but it does work like its supposed to. I really it and use it all the time. Easy to install. Doesn't leak. Very durable. Also the stickiness could be better. But overall, a very good product! Would definitely recommend.

I bought for my jeep i ended up using for my trailer easy to install

I generally do not write bad reviews, but like to work with the seller to resolve any issues, but here goes…I purchased the Jansite TPMS Solar Tire Pressure Monitoring System a few weeks ago, after researching several systems. I chose this one because of the good reviews and the way the display looks.Installation was easy. I had to re-pair two of the sensors but it then displayed all four pressures and temperatures.When installing the outside temperature was 45 degrees. A few days later, the temperature dropped to 12 degrees. The temperatures on the unit remained around 40 for all tires.I then upped the PSI in all tires from 31 to 35. The unit did not reflect that. It continues to show 31 and 32 PSI.I emailed Jansite four times about that issue. They asked me to re-pair the sensors. Nothing changed… The other answers I got was that there could be leakage (I know, but not 4 PSI in a few minutes), and that 4 PSI difference is acceptable, and that the temperature is from the inside of the tires.I asked several times for an exchange or a refund, but I have not gotten any answers other than that the numbers are normal.To me – 4 PSI difference is not acceptable. Maybe I just don’t understand TPMSs. But the PSIs and temperatures not changing at all makes me not trust the system.I am going to purchase another system from a local car parts store so in case of problems I can work with someone local.

I've had this unit for a year now. Initially I liked it, but the internal battery doesn't last long. I've read some comment on the batteries in the valve stems going dead, but those are still working for me, it was the one inside the unit itself that stopped accepting the solar charge. And if I charged it full with the USB, it lasted about a day or two before being dead again despite showing it was seeing sunlight to charge. I tried to get a replacement battery from the local Batteries+ store, but they have nothing that works. I wrote the manufacturer through their web site asking if they sold replacement batteries, but never heard back. So this unit it priced well, but seems to be meant to be disposable. In my case it lasted about 8-10 months before having issues. It still works now, but would need to be plugged in. I ended up buying another brand unit that I hope lasts longer.

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.Update 6 months later: the device dosent hold a charge like it used to. I used to be able to just leave it on all day/night and it'll slowly die/recharge. But now it seems like it won't last 4 hours before going to one bar of battery left. It still works, but now whenever I check tire pressure I have to manually turn it on and off to save battery.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)

This product performs well, and is accurate. Installation was very easy. Charge the unit, turn it on, install the sensors.In my previous review, I described a failure. Jenny at Jansite was very helpful--she sent out a replacement unit which I have installed and it appears to be working fine. Thanks again, Jenny, for your excellent service.I would recommend this product

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.
