This VR Box is version 1 which is very bad in every aspect. It is madeup of plastic but still strong enough. We have to open one slider and fit phone in it and have to use beads or paper so that phone's buttons can not clicked itself. You can also adjust lens accroding to your eyes.
Pros =
Strong build quality | Phone is strongly held in the slider | Have one opening for Camera | Opening for charging & earphone | Cones with bluetotth remote | Adjustable lens | Stripes to held it on you face.
Cons =
Lens is made up of Plastic.
But as I said VR Box v2 is still better then this VR Box v1 because in v1 you will face many dificulties like lens quality is poor, Stripe is also of bad quality. So go for v2 because you will get Better quality in same price.
