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.

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

I purchased two of these for my vehicles. So far so good. I bought them to replace two other similar tire pressure monitors that failed after about a year. Not this particular brand though. In any case these are working great and it was nice to find that they had type c USB connectors which the old ones did not. So now I only need one kind of connector in my car for my phones and the monitors when they might happen need to be charged which isn't often as long as I get them outside every once in awhile. And if they do need to be charged they charge very very quickly. They seem to be a little more accurate than the ones I had previously. The only reason I didn't give them five stars was because on one units one of the tire pressure valve stem caps wasn't talking to the control. Fortunately there were instructions in the box that explained how to pair any of the caps that weren't talking to the control unit and it was resolved fairly quickly. The second one worked straight out of the box no extra work required. These units are one of the greatest inventions I can think of in in terms of safety for your vehicle, yourself and your family in recent years at a price anyone can afford and will save you hundreds of dollars and hours of time. Prior to having these I once had a flat on my way to work on Highway 17 in Silicon Valley going over towards Santa Cruz which is a very treacherous 2 lane Highway with no shoulder that goes over a mountain pass. I was forced to drive on the tire till I could pull over which way that time the tire was wasted and it cost me $200 for a replacement. More recently I had a tire suddenly lose pressure in an area in Oregon where there is no cell service on Highway 101 at least 15 miles from the nearest town right at dusk a New Year's Eve no less. I had recently acquired the car and discovered the spare was not inflated and I did not have a tire wrench. I could have been stuck there for a very long time but fortunately I was able to flag down a tow truck they just happened to be driving by. But again I had to replace the tire. These events are few and far between but always knowing the moment you get in your car what your tire pressures are and not having to worry or kick yourself later because you didn't look around the car and check all the tires before you left is worth so much more than the price of this item. As far as the function I will say this, the display is very bright and easy to read with multiple colors with different colors for each function. If your tire pressure goes below a certain level it starts flashing and beeping, you won't be able to miss it. And the same if the tire gets too hot or becomes over inflated on a hot day. Just checked what the maximum pressure is on your tires and set the to go off some degrees below that. In my case the max pressure is 50 lb PSI and the same for the low pressure. But anytime the car feels a little off the first thing I look at is the monitor to see if one of the tires is low. So far I have not had an event with my tires since purchasing these but the security of knowing at all times even when I'm driving with the tire pressures are is really reassuring and an excellent device well worth the small pittance of money it costs. Thumbs up!

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.

Tenia miedo que fallara alguna pieza el único problema es que la batería de moneda que necesita se descarga rápido menos de 1 año de uso , tuve que reemplazarlo la pila nada más, pero cumple y hace lo qué dice , mi esposa no le entiende pero es muy útil, gracias a eso me di cuenta que una llanta tenia clavos la lleve a checar la llanta y tenia 3 pilas enterradas por eso se bajaba la llanta cada rato

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.

Es importante tener en todo momento la seguridad en la orden de las llantas y lo cumple claramente. No son los mejores materiales, pero suficientes en calidad de acuerdo al precio.

Bought this as I destroyed a tyre by driving on it when it was low on pressure. Very easy to installed and charged battery only once ( Solar charge keeps it toped up ) . Great for reassurance that everything is as it should be with tyres.
