Negative Positive
Title: $15 piece o'crap
Review: It is noisy as heck, you have to move very slowly to get it to work or it will miss the stud. The depth selection would be useful but doesn't work. The ac light goes off and beeps on every square inch of the walls I have tested. The instructions say it will detect ac up to 18''away from the line. It isn't a very useful feature unless you really just want a general idea which walls have ac in them(you could just use common sense in most cases). This product is barely usable to even hang pictures. It will be going back as soon as I get the dang battery out.
Is the review positive or negative?
