Would Not RecommendDidn't work and even if it did it would be hard to read since the lights are all in the same compartment.
Total waste of money, this thing is almost useless
Would Not Recommenddoes not work well, better off locating an elect outlet and measure from the stud there.. this thing is worthless not worth the money at all.

Studsensor L40
Would Not RecommendIt doesn't work, thought if we bought a more expensive one it would be stronger. Don't waste your money. Should have kept my receipt and taken it back.

Excellent...BUTTTTT........
Would RecommendI have the less expensive Zircon stud finder, but didn't have one in Fla. where I was working for my parents. So I decided to "upgrade" to the one with the electric current tester. Problem.....in a wall with metal studs, electric current was "detected" throughout the wall......regardless of where the tester was located. To make matters worse.....once electric current was detected, the current detection light would NOT turn off. It was detecting current EVERYWHERE....including on my leg. To make ...

Did not work
Would Not RecommendIt can't find a stud behind standard drywall. Yes, I read the directions and put in a new battery. Wound up with four holes where I should have had one. I'll be returning it tomorrow.

ok, not great
Would Not Recommendgave me a general idea of stud location but still had to drill test hole - would go back and forth over stud trying to narrow location down, sometimes good sometimes wrong. seemed like good design, easy to use and had the features I wanted, just didn't work as well as I hoped didn't spend a lot so I didn't lose much

Worst purchase ever
Would Not RecommendThis thing cannot find a stud if it's life dependent on it. I've read the directions. Used it and now have 50 holes in my trim because the accuracy is horrible

Find something else
Would Not RecommendBought this just hours ago, dropped in brand new battery and it very accurately misses every time. I have studs showing up at 2 1/4-2 3/8" wide and half way into switch boxes. Will be returning this tomorrow for a refund and maybe looking for something at HD or on the web as lowes only carries one other super el cheapo finder. Do your self a favor and find something else. Dont depend on this cause its going to you in trouble.

Works great! And reasonable.
Would RecommendI've had a series of stud sensors and found them rather hit-and-miss. I bought this today to find studs for bath grab bars, and it was more reliable than anything I've had before.
a lot of misreadings
Would Not Recommendit is a nice product but but there are to many misreadings. so many times i drilled where it told me there is a stud and there was nothing! it also shows me sometimes cables where are for sure none!
