I've got 'em on my other cars and they work just fine. My wife and daughters have spotted problems before they would otherwise have known....you gotta take a look at 'em

We have caught most problems when we see yellow on the indicator.....
Most Women probabily wouldn't feel a difference in handling with a low tire and not too many look at their tires.
I tried 'em on my Z and they look pretty STUPID:(
I bought tire sensors from GM Parts Direct for approx $250.00 and had Mr. Goodwrench turn 'em on for me with his tech 2 and a magnet....I know him and there was no charge to turn 'em on:cool:
There was a charge to have the tire sensors installed on the wheels.....I think it cost me $20.00 or so.....
