I bought a Cardboard a while back, but that was the first generation. And the first gen had plenty of rough edges—it didn’t fit big phones (even though my phone at the time was still a Sony Z1), and there were hardly any apps (aside from a few demos there was basically nothing to play). Then recently I stumbled on the fact that YouTube now has a proper 360° VR video channel, and that’s when it hit me: the second-gen version of that box from Google I/O was already dirt cheap on Taobao.
