It certainly does what it says! I had a bit of a hard time putting it on, but once it was all hooked, I couldn't believe the amount it smoothed and reduced inches. I think it took off at least 3 inches off my waist and torso! I am getting married in one month. This cincher will definitely do the trick under my dress. I can see why you need to train 1-2 hours/day to be comfortable wearing this.
