Stud finder very accurate
Absolutely the best bit of kit I’ve bought in the last 12 months. The ability to find the center of a stud is a game changer for me. I love how it lights up green when the center is found, goes that extra bit of confidence. The electrical sensor works great too, but hard to know where exactly the electrical wire is, the sensor just lights up a yellow led shaped like lightning. I am presuming it’s the center of the device it is alerting for. Either way, it’s the best sensor I’ve owned. A++

Good for stud finding, but not good for cables
Good at stud detection, not so great at cable and electricity detection. It is easy to use and is light, though I am not sure it would survive many drops.

Excellent performance
Excellent product, hard to believe how much better this is than all the other so-called stud finder I have tried. Expensive, but at least you will not be wasting your money again.

Detected power no problem.
Used this to avoid power cables when putting shelves up in she’d. Power cables are running through the walls. Works well.

Electrical detection is not great
Reliable for finding studs through plasterboard, however, the electrical sensors are rubbish, sometimes detects, sometimes not, often detects when your at least 200mm away, can’t trust it for electrical detection but as a stud finder, great!

Didn't work
I just bought this and tried it for quite a while using new batteries. Didn't find any studs in walls, floors or ceilings. Sent it straight back. (It did seem to find some electrical cables but this isn't what I bought it for)

Great product
Great piece of kit. It is very easy to use and takes the guesswork out of finding studs and electrical cables in the walls. The only improvement I would.like to see to make it five out of five would be for it to identify where exactly the cables are, as far as I can tell it shows you that they are there but doesn't pinpoint their exact location. Having said all that Inlove this little de ice and it makes drilling walls much less stressful.
