YONUGFLY Tire Pressure Monitoring System, External Tpms Tire Pressure Monitor System with Solar Charge, Real-Time Pressure Temperature Safety Alarm LCD Color Display with 4 Sensors & 6 Alarm Modes

Really does help me monitor my one tire that is always leaking.

Overall I like the unit. However, I have the unit set on fahrenheit and the temperature runs about 20 degrees cooler than actual temperature. Otherwise it runs fairly well. I would buy it again.

Excellent

Works fine until the 30 day return window is over. Then quits. A random series of button pushing may get it working temporarily. Then it dies completely.

Very difficult to setup and very poor quality. You get what you pay for

Very hard to change the temp to Farenheith and pressuer to Pounds, and set the clock. There is only 3 multifunction button on it. But once I did it, it works and has a easy to read display.The right rear sensor will not read above 43 psi. I put them on my truck that had 60 psi tires. That senser reads fine until it is up to 43psi and when that tire is at 60 psi, the sensor still tells the tpms display that it is at 43psi. I swapped the sensor to another tire that was reading 61 psi and that sensor reported 43psi. I works ok a less than 43psi so I moved the tpms display and the tire sensors over to my other truck that needs only 40psi in its tires.

I like the fact it measures tire pressure so easy, but I dont know if it actually measures PSI.

I tried to changed the battery with another sensor's battery, but it still didn't work. The alarm would go off every 10 minutes or so due to the bad sensor. The alarm is way to loud. I wanted to throw it out the window every time it went off. On the pro side, the size is nice, the color screen looks good. The low price is very good. I bought the Tymate RV TPMS system instead. it worked good right out of the box. I tested the alarm and it was just right.

Es mucho más compacto de los que aparenta en las fotos y funciona inmediatamente en cuanto instalas los sensores en los neumáticos.....marca en atmósferas (BAR), no encontré si se puede cambiar a libras (PSI); pero cumple con el cometido aún en automóviles lo suficientemente antiguos que aún no usaban sensores.
