so far I really like this tool. It reads TPMS sensors very quickly. Programming is easy to understand. It can be plugged into the OBD port to diagnose TPMS issues and activate and program sensors. It can get sensor ID from vehicle or TPMS sensor to program new sensors. This kit contains 4 programmable pickups at 315Mhz and 4433Mhz which is strange because I thought Autel only sold both pickups. So far I'm very happy with this tool. You no longer need to stock many different sensors. The only thing I wish this tool would do, and maybe it does, which I haven't figured out yet, is if it could scan the sensor and tell you what it's for, what brands and models it is. The only way to read the sensor is to enter the vehicle information first. It's great if you don't have a bunch of sensors you don't know where they came from and then rely on guesswork and verification.
