Good built quality , lens are very clear and effective , sound is good , but a littele bit heavy , price should be a little bit less . Not upto best experience what I think before purchase . Premium looks at product , best part is in built ear phone , in built volume controls, 3d film effective , over all good VR box , but one thing you should very clear before buying it , you mobile should have high ppi like 500 or more , then you will experience the best .
