They work.
I have been wearing these now for 3 months. They work as advertised. Only complaint is the width from hinge too hinge is too narrow. The ear pieces are quite sturdy so they squeeze at the cheekbone area. I have worn cheaters for 16yrs and this is the first time I have had a fit issue so I don't think my facial geometry is unusually wide. I love the design concept and will try to find another brand that fits better
