Being a contractor for 25 years I know how to calibrate a stud sensor... this is the biggest piece of junk I’ve ever bought!!! I wished I could get my money back!!!
negative

Product was exactly as described, worked like a charm. Good quality material does what I want to do, and looks great. I would like to see a few more aluminum crimps in the bag to do multiple loops on the cable in the future. Overall great product.
positive

I love the watch band. It is comfortable to wear and easy to adjust. Great product. I did not use the screen protector because I already have a Bodyguardz.

positive
