Check out the vid reviews in that thread. Seems reasonably good experience. Main complaint is tge black level, but brightness adjustment not implemented as of yet.
Controllers & lighthouses & other accessories will be hopefully out b4 the end if the year or early 2019.
Good news it looks like glasses will fit. The one fellow at the meet had a fairly large set (assuming he wore them).
Pimax should consider selling tge cloth strap seperately as it's improved over the original 4k.
I order both an 8k & 5k full package. So will be able to direct compare.
