I've been recommended the product by a friend who had them fitted on his German saloon. I was impressed with their functionality and the other thing that I like is that if you go for the Platinum Package you have pressure sensors and a five-setting heat switch. Quite often I find that cheaper seat heating can be either off or ON and I want the ability to modulate the heat.

Lastly, I'll come back to you once I pick-up the 3W, on your various questions.

Cheers
