The Quality of the mask is totally fine.
There is a small rubber stripe in the Mask, which is located on the forehead. This stripe makes the mask really comfortable to wear.
The small device, which is used to turn the LED lightning on, has a pretty comfortable size and is not to heavy.
The turn ON/OFF process of this small device is hearable, which can disturb a lil bit, but actually the small box gets anyway placed somewhere in a pocket, so no big deal.
