Very size adjustable
I don’t understand what the seller means in the statement that the unit is not rechargeable. I think that is a misleading language translation. I’ve tried to figure it out, but remain confused. The unit heats up very quickly and very warm, though other buyers have complained to the contrary. My only dissatisfaction is that the mesh irritates my under chin and neck. I have to stick a soft cloth between the unit and those areas. Wish the fabric that is in contact with my skin was a softer mesh or non-mesh fabric.
