I never played my Switch in handheld mode without instant hand pain until I got the Satisfye hand grip. I’ll sound like an infomercial for that thing but it’s true. It increased my handheld playtime but a thousand fold. Xenoblade, Skyward Sword, Metroid Prime - anything that uses the shoulder buttons basically - only able to play handheld due to that stupid grip.

I’ve got a Steam Deck as well, which is great, but that grip made it possible to use my Switch again without having to take over the living room TV.
