Ah, that's interesting. I haven't seen the new Blitzwolf BW-VR3, but I have tried the older model. Does the BW-VR3 allow people with glasses to wear the viewer? On the old model, unless you had very small frames it was impossible to enjoy with glasses on.
I totally agree on the issue of buying a phone that's $$ and only going to be used for one thing, lol. It's crazy, but that's the problem with the market right now. You've got the Rift and the Vive - that's it. I can't think of a single dedicated viewer on the market other than those two that are proven and reliable. There's about a half dozen companies that are promising one in the Fall/Winter, but.... Google cancelled plans for their dedicated viewer a while back; while Samsung says it's working on one.
On another note, I'm going to send you a PM....!
