I think this item was previously returned. If you wish to purchase an extra set of comply they are comply 160. But its been cold. Lil clunky. This waist cinched has given me more results in a short period of time than others I have tried. They are a good quality slide at a price that was right for me. They?re easy to slip on, too. I loved them! not these days, not anymore, or you get what you pay for. Thing with these is they just dont produce good sound in the 7.
