Im buy google cardboard from flipcart . It looks very cheap. As it made from cardboard . It is not so comfortable . As compare other vr handset it not that much comfortable . But overall vr experience is very good . We can enjoy the theatermax technology , 360 videos, 3d videos overall the cocept is superb. It is very cheaper than other vr handset like samsung gear vr, occulas, one plus vr . But I am not happy with google cardboard
