Having used it on two jobs since purchase a month ago, it has exceeded
my expectations on drywall covered walls. Initially pricey at $50, the
ability to locate and mark the center of studs on a cabinet run wall

Sorry -- Can't use it or any other stud finder since they always goes off
when I hold it. I have to get my wife to do it.

(Even sorrier --- I couldn't resist)
