After a serious medical problem, I had to start a serious weight loss program. I bought this belt a year ago when I was tired of drilling new holes in my old belt. I used to have adjustable straps, but this strap has an innovative mechanism that makes it easier to adjust. Every few months I'll open the lock, snip off a few more inches of skin, and be ready for a few more months of serious weight loss. I'm 2/3 of the way to my destination and the belt is 8 inches shorter than when I bought it; and it's almost time to cut a few more inches. If you are losing weight, this belt is a must for you!
