I bought the 12v one for 20 bucks from halfords, I think its pritty amazin, so fast and is not even boring to use, Ive found once ive started I just want to polish everything insight ha, I even used it for the center of my steering wheel today lol Very Shiny Now! And what ste says!! Get a woman to wipe the polish back off i personally like meguiars polish(the one in a purple bottle) as it is so easy to wipe away and leaves a nice shine!
