This thing works great--when you know how to use it properly. You have to have the device against the wall before turning it on. While holding it against the wall, press and hold the button on the side (it will do one long beep and the light will stay green- DONT LET GO OF THE BUTTON), now swipe it across the wall. It will beep and glow red once you've found a stud. If you press the power button before contact with the wall, it will give false readings. It's a great bang for buck (I'm just hanging shelves nothing serious), but it's a bit frustrating to get working right away. Also it doesn't come with a 9V battery, so there's that.

works

I got this today and I have tested it already and found it works perfectly. To those who wrote that it doesn't find the stud or they can't figure it out are simply not reading the instructions correctly. Put the sensor on the wall. Press the button and DON'T LET IT GO. Move the sensor across the wall until it beeps repeatedly. That is one edge of the stud. Repeat the process from the other side of the stud and that is the other edge of the stud. The middle of those two marks is where you drill. This is an excellent value and works like a charm. 5 stars all the way.
