Hello friends today I am sharing my personal experience using about google cardboard virtual reality this goggles are very useful to make your smartphone vision virtual reality I have used it was awesome working to use it you should download cardboard application from google playstore this application helps you to dived your phone screen in two parts and then you can set it in your cardboard box and enjoy your glasses but the main minus point is that your phone should support cardboard application then only you can use it and only few smartphone support this application
