Already alone the support makes the seat less cold. If it is really necessary, then heated rapidly - alledings the highest level is only for hardship and unbearable. Stage two is lukewarm and ok. So the performance is very good! Unfortunately, the rest on the back is too short, can not be secured well and slips. The cable is actually too long and the buttons also placed doof. Well, anyway, I'm glad I got the pad as low and I have already the second winter in use.
