The elastic belt itself works well but the poor stitching holding the buckle to the belt is terrible. I bought two of these and both broke at the buckle within a few days of use. I used to buy rubber bands and I really liked them. But they are of poor quality. The seams form a perforation that tears easily. As if they were made to break. It is very bad to be in public with a belt brake. I managed to stretch the belt itself enough to tie it in a knot to keep me going throughout the day. I will not buy this company again.
