Notes on ergonomics: (Google translator)
It is necessary to increase the length of the vertical strap by a few mm, maybe 1 cm. I have it to the limit. PSVR has the same problem but it cannot be corrected, if I lower it enough to see the lenses centered and sharp, it hurts me. I have not tried Rift S.
It also has to have more friction at the nape, I have bought a rear padding that increases the friction so that it does not slide up gradually, which increased the pressure on the forehead and cheekbones.
Alternative facial masks are needed for high cheekbones like in Go, although I had to cut the gap for the nose in that Go mask. Should be included in Quest Slim/Del Mar.
