The product is so useful and so simple. Knowing the actual pressure and temperature of each tire, especially when it's hot like in Texas, can give you a lot more confidence on the road. You can't beat the fact that you can install TPMS on a trailer or any vehicle in seconds. I actually had a problem with one of the sensors on the first one and I contacted the seller, they answered me immediately and sent me a new one urgently, they also told me not to hesitate to contact me if I had any problems. Best experience I've had with the seller so far!
