I'm comparing the Quest 2 vs this on VR-compare and i dont see how this competes with the Quest 2 let alone the third. (so much for competing vs Quest Flagship)
VS the Quest 2 it's got the same resolution (albeit 2x lcd instead of 1x), around the same fov, same ppd, Lower refresh rate (90hz vs 120hz). It's also about 3x the price of the quest 2.
The only thing it's got better are color cameras for passthrough, then we'd compare to the Quest 3 and it's losing in pretty much everything, otherwise matching.
Props to them tho for offering these free accessories
