Everything works great. Cables are thick, pads are soft.
I integrated this heating system to the Opel Astra J's original heating control panel. I am using it as original on 4 seats, only bottom sides. Heating is good, pads are durable and soft, cables are thick, works as described. You have to find someone to fit the pads under the seat covers if you have no experience. I removed the middle console for fitting the cables under the mat, so you can see no cables around.
