I'm trying to determine if I like that design or the Tire Pressure Monitor built into the valve stem. With the valve stem model, you place the cap over the schrader valve to protect it. The cap shouldn't see any pressure. Problem is if the Monitor fails, the tire has to be pulled to replace. With this design, you don't have to worry about pulling the tire to replace if it fails since the cap has all the electronics. I guess my concern is that the cap must depress the schrader valve to determine tire pressure which kind of defeats the purpose of the cap....
Sigh, I'm getting too picky... I like it...
