I have been using different TPMS for the last 6 years. Since the batteries ran out, I bought this new TPMS. The quality seems to be good. It's been two weeks since the installation, and I've noticed that it takes 5 to 10 minutes to report the actual tire pressure when you start the car every day.on the first week of the installation, one of the tires had mild leakage and the air went down to 26 PSI instead of 32, but this TPMS reported only after 10 mins, by the time I drove a couple of kilometers.My old TPMS had been used to report the pressure immediately. This allowed me to know immediately if the tire had gone flat while the car was parked and allowed me to fix the tire before we could start the trip. I feel this is more important and found missing in this product.
