I share my experience with tantra 3D VR Box. When I use this VR device in my Samsung Galaxy J7 then I found that the quality of pictures is very clear unique because it is super HD viewer with adjustable screen makes me complete comfortable.
I also run 3d games theni feeling very well. Sometime I feel that I am playing boxing in the game.
Body design of this VR Box is good and most of the great thing there is no battery required so I have no tension for charging.
it is very costly that is why I satisfy only 80%.
So my experience with my personal opinion that must use this device because this is good for me and I hope for you also.
