Anyone tried the walabot stud sensor?

Have a project to install some recessed cabinets and thing there is some wiring in the way.  Could just wait to get into the wall so I really don't NEED this but think it's a pretty nifty thing if it works reasonably well.  I saw a post here but it is several years old.  They have a plus model for about $20 more.  Hard to tell if on line reviews are unbiased or not so wanted some input here.

I've been tempted by it, but after reading many negative reviews on Amazon, I decided it wasn't worth spending the money.
