I fell for one of Mr Hill's reviews on the Xreal glasses.
They turned out to be far below the threshold of a usable product and a lot of it hat to do with the fact that none of these glasses seem able to match the eye spacing (IPD) of a Western male (or Asian female): if you're not in the sweet spot of that hardware supports, your experience will be terrible.
Mr. Hill seems to be well inside the IPD sweet spot of these glasses so he tends to gloss over that aspect.
There was also tons of issues with the software: it never delivered anywhere near what Xreal seemd to suggest.
I recommend you be very careful before buying any of these and make sure you can return them if they do not immediately fulfill everything you hope for: all of these are both highly experimental and suffer from pretty near non-existent long-term support.
