If you are a competent person then this belt is for you. If you struggle with common sense, everyday life, and everyday objects, skip this strap. It does not stretch like other belts. I needed a non-stretch belt that looked clean, professional and did the job! Under wrap design to say that the 'extra' part of the strap goes under the strap compared to the others. It's not a problem as other reviews say. His common sense. I like the ease of use. My waist is exactly 37 inches on the tape measure, I ordered a medium size and it is too long. but i cut it and it is ok. Forget the bad reviews this is a great strap if you need a sliding strap.
