I’ve tried a few budget stud finders in the $20–40 range, and most were unreliable—one didn’t work at all. This one, however, is flawless. It comes with 2 AA batteries, so it’s ready to go right out of the box. It immediately located studs with an audible tone, and also detects wires and metal. I especially love the built-in marking hole in the center—it makes it easy to pencil your spot without guessing. Excellent tool and well worth the price.
