Quiero decir, que he sido un usuario de años de Samsung de gama alta, y cuando empecé a buscar opciones para un nuevo móvil, me encontré con está marca totalmente desconocida para mi. With some leveling adjustments they will work great. Authentic Samsung item. My husband has had ankle surgery and in addition to a high instep and a size 13 foot, his ankles are quite large in circumference. Didnt realise quite how small and ineffective this would be, graphics are tidy but the actual design makes this kind of pointless. The instructions mention this, but I didnt tighten to the level specified at first, and the stand slowly started to lean while I was working on the first bike I put into the stand. 5-3 hours of playback. Will update if they dont hold up over 6 months.
