Heats good, bad sitting

The cushion heats up relatively quickly and provides cozy warmth even on the back. The mounting options are but lousy. Firstly, the plastic hooks are very small and fragile. On the other hand the elastic band for attachment to the back rest is designed much too weak. Result: The seat cover slides down, so that it must be readjusted again at every boarding. For the price, the rest is acceptable, but nothing more.
