The Rupes machine is a wonderful upgrade from my previous under powered machine. What this review is really about is the outstanding service delivered by Jaxwax. Like a ***** I ordered the wrong product, intending to purchase the 15mm polisher and chose the 21 instead. Two quick emails to their sales support at nearly 11pm ON A SATURDAY and my screw up was revised. They offered to refund the difference or toss in some Rupes pads to cover the difference, which I opted for. I received the fine polishing pad and the medium wool Rupes pad which is highly reviewed across the web. I love it all, but most of all I love quick quality service from a merchant and Jaxwax delivered just that.
