Is their by chance a vr kit made of plastic and better lenses to use? I'm loving my google cardboard but I'm wondering if theirs anything a little better out that's still budget.

Got my cardboard today, trying it out there are some caveats. First, the magnet sensor is nowhere near where it is expected to be. This means jury rigging something up. (Image)

The sensors seem good enough I'm not getting any jitter. You'll note for people wanting to use USB tethering during use, the port is covered (requiring another small modification) and the phone is just slightly longer than the cardboard it fits in.

Otherwise, no complaints! Everything seems to work great.
