I love that it is adjustable (3 rows of hooks) to your size. As you loose weight you can to the second and third row rebore you buy another one. I have owned so many different (and expensive) waist trainers and so far this is the best one. The latex is not too stiff and is a bit more flexible than others that Ive tried so you can move a little easier. I wore it to do some yard work and my goodness it makes you sweat! Also, If you get the right size it is smooth under your clothing. If its cutting through your skin its probably too small. I am 5'1, 168lbs, 34 inches around the waist and 40 around my belly  I ordered a large in black. I am difinatley going to buy another.
