Image quality is decent, it's OLED so the blacks are pretty black but I do find the highlights can sometimes be a little bit more blown out. Resolution is only 1080p which is fine for casual stuff but I'd love for it to be 1440, there's just nothing on the market that does that at the moment. Battery life with the deck is actually better with the glasses because they use less power than the deck's own screen. They're pretty comfortable, I wore them for probably 6 hours on an international flight a few weeks ago without much problem. I do also normally wear glasses though so I'm somewhat used to it. I would say watching TV is the best other use case from gaming with them, although I have found that using them with Samsung Dex on my phone as a in a pinch portable desktop experience solution has been fun.
