Vr box is a technology to feel 3D environment. It is good. We adjust this box in any mobile and feel good. It is a plastic matireal in short cost. It contents strong body. But it contents negative view
It is not show good in conforbility.
It lenes not tighly fix beacuse of this lens may broke.
It is not for spectical boy.
Thus it overall view is good. I suggest you to buy a quality VR box because it may good feel about 3D environment.
