Vážení mám dotaz, zakoupil jsem Ultrahuman prsten, dle navodu jsem ho nechal 30 nabit (dioda na nabijecce blikala bile), pak jsem se pokusil prsten pripojit. Po nasazeni na nabijecku nezacne tato blikat bile a prsten se nepripoji. VYzkouseno na dvoiu ruznych telefonech. Mate nejaky tip na napravu nebo mam primo reklamovat?
