Seems to work well. Perfect for quick measurements. Has some nice calculation features built in. Screen is much more vibrant than it appears on the photo. Good tactile buttons. The case it includes is a little snug for the device, but good to protect it when not in use. Excellent price for what it can do.

I have to admit I was a little skeptical due to some negative reviews and low price but decided to give it a shot. So yes, you can't just blindly trust to first detection signal you get as you might get different results. But you can ensure overlapping results to ensure you get right reading. To do this I used two passes: Stick on wall 2 horizontal lines of painters tape, so that second one is below first one (in my case ~20 cm just to prevent if I hit some horizontal obstructions behind the wall) 1. First pass is to go with device left to right and mark (both beginnings and ends) on painters tape where you get reading, then do in opposite direction from right-left. If marks are matching than you're probably already ok. 2. On second line below repeat same procedure. That's it, find where you see overlapping and this is your studs. Aim to drill in the middle between begging and end markings and there you go. If you still have doubts, on every measurement tape there is little triangles with standard distance between studs, so you can check this as well against your markings. It should match.

Great tool.

Good measuring meter, I recommend it!

Very good value, works good.

Love this thing. Wanted this type of tool for a while but never saw a great deal until now. Works like a charm.
