Review on Walabot DIY Plus - Advanced Wall Scanner and Stud Finder for Android Smartphones (Not Compatible with iOS and tablets) - Model DY2PBCGL01 by Damon Atonyo

I calibrated 4 times before even drilling the hole. Each time he said the hairpin was in the same place. I drew the outlines of the holes I was going to drill and it turned out there were no studs. I thought I was confused. I calibrated again, he still said there was a hairpin. I used every mode they had and it always said it was there. Then I tried to find another pin and the device showed multiple pins next to each other. I drilled another hole and all it was was drywall. Now I have 2 holes in my wall because of this stupid device that doesn't work. DO NOT BUY THIS. IF YOU DON'T BELIEVE ME, PLEASE FIND THE VIDEO ON YOUTUBE. I will be returning this item even though it has been used, hoping for a full refund.
