Cheap, and It Works
Took the wheel off of a 2010 Ford Fusion to fix a flat. When I put it back on and started cart he tire low pressure light wouldn't go off, which has never happened to me before. After some online searching I saw this gadget. It was cheap so I didn't risk much. It worked like a charm. The instructions included told me how to put the car in learning mode (but that info is available online). After getting into learning mode it tells you to calibrate a specific tire; just put the antenna next to the valve stem. A light on the box comes on, and after a few seconds the horn beep. Display tells you the next tire, and after you do all four turn the key off and you're done. (Don't forget to take the battery out because it might be years before you need to use it again.) The markings for how to insert the (V battery could have been clearer.

Worked Right Out Of The Box
Worked first time no issues on 2010 F-150, I put my truck in TPMS learn mode went to each tire in the order you're supposed to and that was it. My light on the dash is off. Would definitely recommend.

Did not work for my vehicle.
Did not come with clear cut instructions. Not compatible with my vehicle. I could not get it to work. It would not read my tire monitor sensors I do not recommend this product

Good, but needs to transmit stronger.
It works but it’s a bit weak. Took multiple tries to get a response from the first sensor. Even more for the second one. It takes awhile to get all four because sometimes the sensors just don’t receive it before the vehicle times out. I tried buying four new batteries and replacing them as I walked from one wheel to the next, so there was maximum power each time! hahah. Now I have more invested in batteries than I do in this unit. Not bad for the money. Sure beats the dealership bill.

Simple, just read the manual
Simply, it worked. Put in the battery, got the car TPMS system in the "learn" mode (hold down some buttons in the right order until the horn chirps - see you manual) Then walked around the car starting with the front drivers side tire. One button to push, wait for the horn to chirp again, on to the next: front passenger, rear passenger and rear drivers side last. Had to wait a few seconds for the devise light to go off between each tire. After the last tire, a double chirp and it was done. My car is a 2018 Chevy Volt, Devise is suppose to work on all GM and Ford TPMS systems, but only used it for the Chevy. Longest time was spent finding the right section to look up in the Owners manual.
