It seems to have enough charge that I have not recharged it in a week now. This pair has been my greatest success to date - coming in a ½ size they fit almost perfectly. I would have purchased another pair for that price but now they?re listed for $40. - Carrying the bands with you sucks, think about it, if you are going to run and then lift, you dont want to wear the super tight band all the time, so that means you carry both bands but you dont want them to break because you dont want to deal with their customer service (see below), so, its extra hardware you are carrying on your bag. pile of salt. The structure of the flop is rigid with an intelligent break (bend point in the sole). Comes with cable but NO adapter. Bottom - not so much. It was just what I wanted, I have had this type before and it is an excellent product. My shoes fit perfectly.
