I've been using it since we opened our shop about 9 months ago. I have had several problems with it. It's very cheap relative to other underpinners and in hindsight I may have payed the same for a used amp or something of similar quality instead. If you do buy it, build your own table to fit instead of buying their flimsy arm attachments. Also add about 30 layers of duct tape to the pad so it doesn't dent the moulding.
