I bought vr kit on march 2016 its approx two years I have been using it. It is made up of a tough cardboard and it has a pair of lens and a pair of magnets its supports mobile size from 5inchs to 6inchs. It just change the environment and gives you a whole new experience of watching movies, it just change the trend of watching movies till now. You just need to put the mobile inside it and wear it and then when you open your eyes and boooommm its seems like you are inside the movie it gives a new experience of watching any video and there are some app by which you can play games by wearing it and connecting it with a controler, but its a basic one there are many more vr which gives you many other features.
