Quality is cheap, but at this price I think it's good.
Pressing the nose ask to add a foam.
Otherwise, it holds well on the head, it is light and does not move during rotations.
Ditto for the phone that it remains as secure.
Much more comfortable than the Cardboard cardboard, which both request to be kept with the hands and thus lose the immersion, but also the sharp edges of the cardboard.
The virtual experience is very good, with impressive 3D effects.
It is a pity different applications to see the image of the other eye, because the separation is too thin or the phone too far. This was not the case with cardboard Cardboard.
As the cardboard, it is constantly having to take the phone out of damage to switch applications.

Giving a greater impression of watching an image in the binoculars.
In addition, the gloss of plastic inside reflects the image from the phone.
Settings are used to adjust the gap between the lenses and their depths.
My HTC ONE seems small for this headset (whatever the setting) because I see the banks, this was not the case with the cardboard as the phone is closer.
It's not perfect, but for the price it is a cheap way to have good virtual sensations.
Ideal for watching videos on their phone.
Many applications on Android.
