VAOYAO Tire Pressure Monitoring System TPMS, Solar Power Universal Wireless Car Alarm System with 4 External Sensors, LCD Real-time Display 4 Tires' Pressure & Temperature Alerts Ensure Safe Driving

The tire pressure gauge worked fine, however I did find that the Front Left (LF) tire reading showed up on the Right Front (RF) tire gauge screen area. The fix was easy. I just took off the cap of the RF and LF senders (as if I was changing battery ) and swapped them. The rear senders worked perfectly. The screen is bright and found it easy to see even in sunlight. I charged the unit before using and battery showed full 3 bars. Haven’t had it long enough to determine how well the solar charge works. Happy so far.Update: it has now been 2 1/2 weeks of usage and the guages still work perfectly. Two days ago I got a flat and the guage displayed 10 psi for that tire. The previous reviewer indicated that the instructions were too tiny to read and understand. The reviewer is correct but if you magnify the instructions using a smart phone or enlarger you can overcome the tiny manual. The instructions to change temperature measure and psi measure are a little complicated but I was able to convert centigrade to Fahrenheit and pressure to psi. I also changed the range of the low and high pressure alarms. It took a few attempts but I got it done.

Easy install, was excited because LCD screen worked perfectly and showed temperature on each wheel and the solar panel worked great. Followed instructions to no avail.

I bought this kit to monitor my winter tires pressure. My winter tire rims are aftermarket and it wouldve costed me a few hundreds to install the OEM tire pressure monitors. Easy to install and I could switch from bar to psi unit.

Works very well, adequate pressure and temperature reading and the accuracy is within 1-2 PSI and 1-2 degree. The display is very clear even in the direct sun-light. The sensor for this TPMS system is smaller than other system I purchased elsewhere. It is about 21mm @ 0.32oz versus 22.6mm @ 0.35oz. Believe me 1.6mm doesn't sound like a lot but it looks much bigger on the wheel, see comparison picture.There are a few Cons with this affordable TPMS.1. The temperature reading in Fahrenheit for Rear Right (RR or D Sensor) in degree F reading is broken whenever it is reading in upper 70 degree Farenheit, see attached photo. Initially, I thought I had a bad unit, so I ordered a replacement. The replacement unit did exact same thing. The workaround for me is to set the unit to Celsius to avoid seeing broken number.2. The sensor update rate can be very long, sometimes it takes longer than 5 minutes to update. I did a quick test by removing the sensor, the display unit went into alarm immediately so that function works well. I can't attest to slow leak though, since I can't really test it in real life until I have actual leak. I am sure Temperature High and Low alarm work but I haven't tested it, someone can charm in.Hope this info helps someone make an informed decision before purchasing this TPMS system.

This product is easy to install, but after installation, I found that the FR sensor is not displaying. Even after reinstalling and using re-pairing, it still cannot connect. How can I get a new FR sensor?11/11/23 update:They sent me a new one immediately after I wrote the review and it worked perfectly. All sensors could be detected and the pressure was correct.

The product I received was not working well. One the sensors was not reading. I returned it. I believe this product is a hit or miss, according to other reviews. If you want to purchase it, it's a chance you are going to take.

Cheap batteries, inaccurate readings. 2 read 4-5 psi too low. Temperature off by 20 degrees F on one sensor. Other sensors off by 3-4 psi. Batteries died in first 200 miles of driving. Screen hard to read unless at exact angle. Have to pick up with hands and tilt it to read it. Missed return window by 2 days. Not happy. Had to buy another one while on the road.

I got this because all of my tires have a slow leak. I have to add air weekly. It does a fairly good job of letting me know when the tire pressure is low. The pressure it reads is different from manual pressure gauges, but I can live with that. The problem I have is that when I add air to my tires it doesn’t update the pressure for up to 20 miles. And if I have the readout turned off, it still can take 15-20 minutes for the readout to update when I do turn it on. This can be especially annoying if you park your car for several days, then drive past places to get air and get on the interstate, and then it alarms for low air pressure.
