Review on 🔍 Ultimate 3/4 inch Wall Stud Finder and Metal Detector Sensor - Precision Wood and Metal Scanner for Effective Wall Detection by Eric Wohlman

If I had to choose what would be my worst purchase of 2020, it would be this spike finder. I swear it's just a guess. Look at this picture. I swear; It said there was a bolt in those places and after I gave up I just started drilling somewhere to find the bolt because I knew I already had to patch it. Please do not buy this item. You're more likely to find a hairpin just banging against your wall.
