Review on BLACK DECKER SF100 Wood Finder by Roy Bush

It doesn't work very well and the little foam pads on the back left dark streaks all over my paintwork! I ran the device back and forth on the wall as intended and the pads on the back left nasty streaks that I couldn't wipe off. The wall looks terrible now. Very disappointed. It works only mediocre to find studs. I have a thin layer of plaster over drywall with mahogany spikes and this thing doesn't do a good job of finding the spikes. Thumbs down.
