I use it almost every day to jog, bike, sit-ups or body-building, the first goal being to lose weight at the waist (abdomen, lower back, wrists love). After a little over 2 months of use I am satisfied, ca heats well, it makes me sweat well and I see the results: I lost 7 centimeters in waist circumference. BUT, the product is not of great quality, it begins to relax, the scratches are decousent, and form on my coprs becomes increasingly unsightly.
