Après trois utilisation ! These slippers are the best I have bought. Supera las 10 horas de pantalla, llegando a los 2 días. The left one when individually placed in box will pair and play in charging box, but refuses to remain connected once removed to use. The only down fall is the lock caps are plastic. Theres no feed back on your voice so you cannot tell if you are yelling or not. Very exciting and kept you wanting to read more. I only have three towels hanging at the moment. They feature IPX8 water resistance so they wont break if you sweat heavily with them or take them into the shower, a charging case that has a little screen to indicate how much battery is left, and newly it now uses a type C connector to charge over the more flimsy Micro USB from before. I wish companies would just raise their prices and keep the quality the same.
