Google Cardboard was developed to help consumers have a taste of cheap and easy VR experience. It basically is a platform where programmers can create and share. One needs to have atleast an Iphone 5 or Android 4.0 to use the headset. You need to invest more on the smartphone than the headset itself. The best thing about this is that it only costs $3-$12. It is a great device if one would like to watch simple VR youtube videos or VR games.
