Amazingly Accurate
I used this tool to cut a hole for a charging station in my office. I was super impressed with how easy it was to learn to use and it pointed out exactly where the edge of the stud was located. It made the job so neat and simple.
    Powerful, user-friendly tool
    If you're looking for an easy-to-use, multi-function scanner, this model will fit the bill. It features solid construction, felt sliding pads, an ergonomic grip, and an informative display. But the greatest feature is the red arrow that projects right onto your wall to show the center. No more ball-parking the left and right sides of the stud with a pencil while you pass over it. This capable device shows you right where the center is, and does it in a way that makes it super-easy to mark the wall. The only drawback to this product: the price. Do you really need all of its features if you're doing basic home improvement? Probably not. Zircon sells a stud finder that will locate wood studs just as well for $20. What you get with this one is the multi-color display, metal detector, and AC wire finder. Whether these provide additional value will depend on the job, but they're nice to have if you want to plan for the unexpected.

          Steaming pile of failure
          I’ve never had a stud finder that didn’t infuriate me with false readings, unrepeatable function, etc. this is the most expensive one I’ve ever had and it performs no better than those half it’s price. I followed directions to the letter. I was tempted to spike this thing like a football after the first 5 minutes of use. Total junk.
