I believe that the #MergeVR goggles are the best platform for cheap VR/AR headsets.
Not only are they made of stretchy, flexible Nerf foam, but they also have a pluggable hole for a smartphone rear camera, allowing for both VR and AR in the same headset.
these two features – an AR camera hole and Nerf foam – are *crucial*. No other headset maker – not even Oculus or HtC – have these features yet.
