After about 1 month of use, not even taking it to run or stuff like that, my band is not charging anymore, seriously, after only one month, I've been trying to be very understanding with MS, my fist band was peeling off and looking awful after 6 months of very good care and now this, I am on the verge of giving up the whole windows 10 thing and switch and I was even one of those that urged other to get these products
