Google cardboard is the is the cheapest vr avaliable in the market all you need to spend is 250 bucks and you need to install a app! Performance is great and really durable.
It’s a very good product as compared to its competitors which are too costly as compared to it. But attention to every one. Dont do the same mistake as I did before buying this product please try to install cardboard app which u can get in you app store and if it is compatible with your handset then only look forward to buy this product or else its of no use
