Yeah I suppose there is always a risk of it stuffing up when your out on the tracks and that's why I want to install it myself so I know where to pull apart if it's really stuffed so I can get it back home. As for the other sensors, I want the tilt one so no prick tries to steal my tyres as it remembers the horizontal axis you were last on and the radar one seems like a good idea to me because of the GQ rear sliding windows which I'm sure are quite easy to break into.
