Tire Pressure Monitoring System (TPMS), Tire Pressure Monitor with Solar Charge, TPMS with 4 Sensors & 6 Alarm Modes, Real-time Tire Pressure Monitor System, 0-87PSI for MPV/SUV/Sedan

Good product so far!

Works as intended and the set up was simple. I recommend this product

I ordered this because my "tire needs air" notification never told me which tire was low, so I'd have to eyeball it. Then I'd end up opening them all and giving them air just to figure out which tire it was. This thing tells me right away which tire it is. Then I can choose whether to take the time to pump up any or all of the others. The set up was super easy. I just waited until I needed air, went to the warehouse store with the air pumps and right there in the parking lot, I set the whole thing up and the readings came right onto the screen. It literally took 30 seconds for the sensors to sync to the monitor and show me the tire pressure. This gives me so much peace. I didn't use the anti-theft nuts because I was just too eager to get them on there. I'll go back and add the anti-theft nuts when I get a chance. Knowing that this monitor is tracking all of the things it does - leaks, temperature, pressure - makes me feel so responsible. There are some things I didn't really know before setting this up. First, the PSI in the tire fluctuates throughout the day, I saw them moving constantly between 34, 35, and 36 PSI. The temperature also fluctuates and may not be the same for each tire at any given moment. I mean minor fluctuations, like 1 degree F. I'm going to pair this with my handheld, portable tire air compressor for the car and I'll never need to go to the crowded warehouse store to fill my tires again. I recommend.

TPMS in my car crapped out a long while ago and I've just been left guessing when to refill my tires. I could get them replaced but I hate having to go to a tire store and deal with the tire smell in the store, and mechanics getting my car interior all dirty and having to clean it all up afterwards. This pretty much solves all my problems. These TPMS monitors attach on the outside of the tire rather than the inside, so no special equipment or tire removal are necessary. The caps are made to fit on standard size tire valves, so just replace the tire caps with these and it's done. Monitor system works with RF so no wiring or anything is needed. Just put it anywhere you like and turn it on. Has a built in battery and charges via USB, but that's mostly unnecessary since it has a solar panel and can recharge itself. Strangely, the unit came configured to PSI and centigrade, whereas we use PSI and fahrenheit in the US, and Asia uses BAR and centigrade. Took a bit of messing with the settings but managed to get it set correctly.
