Haven't used these slender tone shorts enough yet to comment on any outcome but having used the slender tone belt (along with exercise) and seen the good results, I'm hoping this will do likewise.
I can certainly feel the squeeze on the thighs. They are a bit of a faff to get on and peel the covers off the sticky pads whilst wearing the shorts, but once you get the knack lying down, it's ok. I wear them whilst running on my treadmill. Aim to wear every other day.
