I ordered this product on payback. 1. Delivery: Product has no charged battery and could not be loaded (either on PC or on the socket). Unit will therefore not, can not be used. 2. Delivery: Product has a low charged battery can, turn on, but that was about it. It does nothing, except that the clock is ticking. Steps are not counted, device can not connect to Handyapp and (that gives me what was known before) do not charge. Apart from that the band would have to be cut to size with scissors, optionally also with a knife or your teeth ... but it does not change the fact that only I or people can use this product with my wrist circumference. The one star there for design, but for the money I can buy a gold bracelet.
