I've had the sam CG lock for 10 yrs and moved it from car to car when sold. It isn't the best solution but does help keep you somewhat in place. As for it breaking not sure what that's about. Rather simple devise and once installed not much can go wrong. I'm on here too waiting for a true harness for track use.
