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

Worked as described.
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.

Decent quality for the price and for what it is
These were good I have a 2008 GMC Sierra 1500 where it doesn’t really show me what the tire pressures are on each tire my sensors on the truck only tell me whether or not there is a high or low air pressure it doesn’t tell me what the actual tire pressure is in the tires, so this comes in pretty handy because this way you can actually see what the tire pressures are in each tire and with your tire temperature is so that way if you’re driving with a load on the back or something like that you could see if your tires were heating up and they might possibly blow out if you didn’t pull over and let them cool down or if you’re driving on the road and say you’re brakes could be rubbing on the rotors it’ll let you know that the tires heating up and that there might be something I want to look into or even if the bearings were going bad and it was causing some heat on if you know what to look for it’s a good helper because it gives you an indication that there’s something that isn’t working correctly seen as how if only one tire is getting really hot, there could be an issue on that tire, obviously it’s not flawless because there’s always a chance that maybe the sensors just bad because I did order different one and on that one one of the tires wasn’t reading correctly it would read the tire pressure fine as long as you didn’t go over 32 psi and the sensor itself wouldn’t ever read the temperature of the tire it was only one tire, so definitely make sure when you’re feeling your tires to use an actual tire gauge so that way you don’t over inflate your tires, and then you can also double check your sensor to make sure that they are reading correctly, I wouldn’t put a bunch of air in your tire and just go off of the sensors for numerous reasons because sometimes they want change unless you’re driving on the road for a little bit, also they just might not be reading 100% correctly or there could be an error with the sensor itself and he’s being reset or needs new ones but they are nice for when you’re just driving on the road it helps you these kind of see what might be wrong, but I’d say normally they were pretty good

Over the years I’ve had to replace many tyres with uneven wear caused by my neglect of inflation pressure. I saw this sort of thing built in on a brand new car and thought thats what I need. Its simple to use.. Charge on the usb, just once, and the little solar panel then tops up. Add the sensors to the values. Press a few button, as per instructions. Job done. However, after about 3 months, I did have one sensor go faulty, but after 2 or 3 short messages to VAOYAO, they sent me a new replacement unit that arrived in a couple of days. So good product and good supplier.

If you take a close look you will find a number of TPMSs for sale. On close examination it appears that hardware wise they are all identical and are probably made by one manufacturer. The firmware, the software that defines how they opearate and what the user interface and menus look like seems to be a completely different matter. Each vendor appears to have their own version, some are OK and some are awful. I wasn’t impressed with the user interface for the VAOYAO device but its main problem was that none of the four pressure sensors would pair with the display unit. I thought at first that perhaps the sensors had been mislabled (The are marked FL, FR etc for front left and front right) and that I was inadvertantly trying to pair a sensor that I was not actually fitting to the tyre valve, after careful checking it turned out that that wasn’t the case. Before I returned the device to Amazon for a refund I did email VAOYAO hoping for some advice about pairing (I have had a couple of similar units in the past that lasted for several years each. I got a reply from China but they didn’t seem to have much idea about what might be going on.

Item functions as explained but security nut could not be fitted as it was too small.
