Part 3. Exercise
Review: When I first received this product I was plenty happy, I thought I had finally (after 8 years of switching from cincher to cincher) found the right one. It squeezed my belly enough that it actually got me to "right-sized" eating (whereas a lot of times I would get seconds, I found when I wore this cincher I could only eat one serving), which of course is wonderful. I didn't mind that sometimes it bunched up, I didn't mind that sometimes it left welts (that went away shortly after I removed the cincher), however, after about two weeks, on of the metal prongs came out, making the cincher essentially useless because it doesn't hold it's form. Even the cheap cinchers at Walmart held up better than this and cost only a fraction of what this cost.
Polarity: Positive
Answer:
False
