do u know, i love mine and can definatley see a difference - there isnt much difference between the 79.99 model and the 99.99 model ( i just have the waist belt) u just get extra pads and batteries with the £99 one lol
i figured that as im on a high protien diet and protein feeds muscles, and as i cant do any strenuous exercise (im on SS) this might have a bonus effect as the more muscle mass you have the more calories you burn - so win win situation lol
i usually just wear it under my clothes as im pottering about around the house.
you can see a visible difference after just 1 week :-D obviously depending how many times you wear it
the other good thing is that it helps my posture and keeps my back straight
