Review (5/5): perfect to get the waist measurement for my body fat ...
First I tried on my arms 45 minutes the first and the second week and did notice my arms slimmed. Then I stop using it and months later I needed to loose some inches from my belly. I used 2 envelopes, follow the instructions also I wrapped over with a wet towel and with plastic wrap and lay down for two hours. I loose one inch an little bit more, perfect to get the waist measurement for my body fat test. I would buy again.
