Review on VIVREAL 4 In 1 Stud Finder Sensor Wall Scanner - LCD Display, Sound Warning & Auto Calibration For Wood AC Wire Metal Detection by Michael Mendoza

I have tried every stud finder available for under $50 at hardware stores and I've been disappointed. Some weren't very accurate, others were confusing to use. This device is great I've tried it and a number of different walls where I know where things are so I could test accuracy and it works wonderfully. It didn't come with a battery but that's not a big deal. I definitely will recommend it to others
