Based ont he reviews it seems you have a very good product. The battery thing still kind of worries me even though your explanation does make sense. I tend to be weary of things like this just because for the money of the clothing, i couldnt see "maintaining" the clothing like a car by having to pay for new batteries every so often. I truly wish i had the money to uy these and write up a review but i just cant especially since its that time of year, i would rather buy stuff for the family then myself. I think the jacket paired with the insoles would be an unbelievable pair. Hopefully as time goes on and your company grows/industry and economy allow for it, the price will begin to drop into my price range.
