Review on 🔋 WonVon TPMS Solar Tire Pressure Monitoring System - 6 External Sensors - Wireless - Car, RV, Truck by Kyle Rock

Despite the low price these work well. You simply turn the unit on and screw on the six sensors like a valve stem cap. You only need screws and a wrench if you want to protect them from theft. The bad part is what others have mentioned - the instructions use too small a font to read and it's very confusing as they did a poor job of translating from Chinese to English. I finally figured out how to change the reading from "bar" to psi and learned how to toggle it on and off (the farthest of the three side buttons). The pressure readings were close to what my pressure gauge showed. Interestingly, I ordered this TPMS before receiving my campervan, unaware that the 2021 Ford chassis came standard with TPMS. So I removed the sensors from the camper and moved them to our car (with two extra sensors of course). The monitor is now giving some sort of warning every minute and I can't figure out what needs to be adjusted. But since the pressure in car tires is quite stable. I only turn it on every few days to check the pressure and then turn it off again. Poor instructions barring, I think this cheap TPMS will work just as well as the expensive ones.
