Hey VR friends. I can't afford a real VR headset, but I just got a free umidigi F1 phone (I don't know shit about phones). And I was thinking of getting one of those google cardboard deals. 
Now I realized there's a whole bunch of different cardboards / holder thingies. 
Do any of you guys have recommendations for which one is good? Which one is comfy? Comes with strap and all you need? Because from what I can tell, the original google cardboard one is designed to be held against your face non stop, and I plan on using the phone as a PC VR headset if possible.
