BUT:
- It lacks the magnet, to operate the programs! I have to keep a my finger on the side of the glasses. This is a great disturbance.
- There is not enough room for the nose. You can not use the device with the bands, because it hurts. I have no small nose, ok, but I think that the spectacle does not fit European face (probably for Asian nose designed). When you stop with the hand, the glasses, still going.
PS: Sorry for my German. I am foreign ...
