stereoscopic glasses for smartphone

Fully satisfied for the price.
Setting the distance among the ocular lens
Adjusting the size of the dark room to fit the smartphone by the 4 serrated plastic flaps that is well maintained and does not fall off when you look down. Despite this there may be noise light inputs so use rather in a dimly lit room.
Compared to google cardboard, it lacks the magnet on the side to register a click. just pass a small magnet to the right to have the same effect (it works well on my Galaxy S3) or no input means because the screen is not available!
If you are sensitive to the definition, it is better with a screen fullHD because here the screen is divided into 2 ;-)
A star less because it lacks the foam in the nose.
