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!!!

I am so excited to get this sweat vest! Fits great zips up easily. Fits and stays a lot better then a normal sweat band or waist trimmer. The smell of the material goes away as soon as you soak it in water with soap. But all and all great product.

so, this thing is like a big fat crochet hook designed to grab the inside lip of the jacuzzi ball and pull. Which would be great, except that it's ONE QUARTER INCH TOO SHORT. Maybe Kohler changed their design to make it deeper, or something, but this tool is next to USELESS for removing jets from my tub. Instead of the ball lip, all you can "grab" is the sloped ledge inside the ball, which with a LOT of persistence and side pressure might eventually get the insert to let go. We finally "modified" the tool by melting portions of the stop-ball away, making it more functional and much less pretty. Caveat Emptor.
