Part 3. Exercise
Review: My size medium was true to size. This made my waist smaller and while I had it on, I didn't eat as much because of the pressure, it makes me feel full; however, all of the cinchers do this as it is its purpose. I did like the fact that it's shorter from the lower back and a bit longer on the tummy... BUTTT... a HUGE BUT for me... What I didn't like was that it made big bulges of fat on my upper back (eewww!)... and I don't even have back fat!!! So to me this defeats the whole purpose! All it did was cover my stomach fat but GAVE me back fat!!! Also, what's going on with the price increase?? I just bought this 3 weeks ago for $30, now it's $45!
Polarity: Negative
Answer:
True
