Lipo in a Box

Have any of you use ever used in of the "lipo in a box" items???? lipoinabox.com/products.htm (http://www. to beginning to make link work) (body shaping undergarments for women) They are also sold on QVC. Lipo in a box website does NOT allow any returns only exchanges for defective merchandise, however QVC has a 30 day return policy. qvc.com (add http://www. to beginning to make link work) (I have purchased from QVC for years ... they are great). With QVC if the product is not what you wanted, didn't fit correctly etc it can be returned. If you have used Lipo in a box, did you find it true to size ... what did you think of the quality of the product? Thanks. Mary
