I'll keep this short: This thing is very cheap, can be attached to just heats in 30 seconds, which is exactly what it should, but it looks mE not necessarily good. It adapts optimally to the seat not to, and therefore is slightly off. We solved this by over it inside out a matching seat cover, which now has the effect, as if it were a seat heating at the factory. Also less than optimal is the fact that the cable runs only on the right side. Thus, the switch on the driver's seat can not be achieved so comfortable when out of the driver's seat side. I plugged the cable into a cigarette lighter distribution - is working properly. All in all a recommendation. The blemishes are a price thing. Let's see how the life is ...
