I picked up one of these and was pretty disappointed.. it works, but not very well.. my $10, 15 year old stud finder is much, much more precise.
Maybe you were more of a stud 15 years ago.
hmm.. maybe.. but I'm married now.. so I'm sure getting more than I did 15 years ago.
#3, that'll change in the next 15 years.
