I picked up a Super Adjustable on the Bay the other day and it's giving me some troubles. The doors open and close just fine and the adjustment dial turns and clicks, however, it doesn't adjust. Instead it appears the whole head of the razor moves up not just the adjustment bar. Also, the middle part of the handle can be unscrewed from the adjuster dial. Is this normal? Should I be trying to get my money back or is this an easy fix? I have it soaking right now to see if maybe its just gunked up. Pics later if they'll help. Thanks
