My DSCVR arrived from I AM Cardboard in HK the other day. It’s a plastic Cardboard viewer, but unlike other plastic viewers (Homido, Freefly, ColorCross, etc.) the DSCVR is actually a ‘certified’ Cardboard viewer because it sticks to Google’s design guidelines well enough.
I’d been wanting something more durable to carry around & demo some of the Cardboard stuff I’ve been working on & opted for the Freefly VR. It doesn’t include any Cardboard style input (either v1 magnet or v2 button) but I’m planning to get a Bluetooth remote & use it to trigger the same events as screen presses would. More thoughts on this headset in this thread on /r/GoogleCardboard, but in short I’m quite happy with it.
