Review on 🗂️ Stud Finder Wall Scanner - 5 in 1 Electronic Stud Sensor with LCD Display - Locate Wood, AC Wires, Metal Studs, Joists - Orange BLACK by Rob Jimenez

Bought this model based on good reviews. I tested it on a known hairpin and it seemed to work fine. Next I wanted to drill holes for the TV wall mount. Also tested this on a known hairpin and it worked. I thought I went to the races. Then I found places to drill a wall mount. The two vertical holes were fine. The two vertical holes were drywall with no studs behind them. Again I checked this multiple times to confirm where the bolt should be. I'm not sure why I got wrong readings after several verification attempts. I have holes in the wall where I don't want holes. Pretty disappointed.
