The previous owner of the car I just bought put together a crazy maze of wires and relays to power the two front windows. I bought this to keep wiring to a minimum and use a hidden design. So far this switch has worked flawlessly and had no problems. The only problem I had was that I underestimated the size of the switch, it's quite a tall switch from the rocker to the binding posts (my fault, not the switch). Overall I'm very happy with my purchase, but if I did it again I'd look at a smaller version.
