I was confused with wide variety of stud finders available in market. Home depot expert suggested me this one. I found it very very accurate and easy to use. It finds edges of studs in seconds. One more important to thing mention is it do warn for AC wire on the wall. My actual planned location for drilling was actually having ac wire on the back and due to this feature I was saved. I am using it for home - get this one instead of cheap ones available in market.

I got this stud finder for simple home projects around the house or in the garage. It’s extremely complicated to figure out how to use and I’be used plenty of stud finders in my day. The thing beeps when it wants not when there’s a stud..

I purchased a month ago. Have been using it ever since. Exactly what I needed and wanted. Stud Finder is accurate. Helping to complete jobs quicker w/o 'extra' holes.
With this sensor I can find lots of studs.This sensor works well.I use this sensor mostly when I want to hang a picture,or drill a hole.I know by using this sensor with the red light marking that I am not going to have a air hole,like I use to have in the olden days.This sensor is worth the money.Home Depot.ca is the cheapest place for this sensor.
I love this easy to use stud finder. Price was great and shipping was fast.
I purchased this to when I needed to put up some shelves in my office. It was easy to use and accurately indicated where each stud was. The small level was an added bonus and came in handy and worked as well as my large one.
The first thing you'll notice about this product is that it provides no instructions as to how to install/change the 9V batter that powers it. You'd think that would be an intuitive process, but it's not. The only method of entry into the unit's interior, which is where I presume the battery goes, is via removing a small phillips-head screw in the center of the back. Once the screw is removed, the back should almost drop off. Right? Wrong. It doesn't. I could find no way to remove the back of the unit, or the black pocket clip that's attached to it, which I suspect is necessary for removing the back. The design is so bad, in fact, the I'd advise again bying any product manufactured by this company.
best stud finder i have used. accurate easy to use., Goodproduct for the money
so excited to find a stud finder at low price like this one. unfortunately, it is a waste of time and money. I can use it to find a stud on every kind of surface including windows. even if I put it on my own body, it shows there is stud found. I don't know the technology too much. but I think it doesn't make sense at all. I have to go back to return it. It just waste my time. don't trust zircon any more. will try stanley instead.
