I haven't really used it yet. It's one of those weird things that you really need to test and all my TPMS sensors are working fine at the moment :-) hehe. No doubt it should work just fine. Autonomous USB charging. Nice hard case. The buttons feel good, the screen looks good. It's nice to know I can reprogram if needed without having to pay the shop or dealer, especially here where the cost of visiting the shop is VALID for the cost of this unit!
