I'd say they probably are, the later versions were redesigned with added complexity. Mine is the old Duo-60 (no airfry/sousvide function) bought 11 years ago, I use it several times a week and have never had a problem.The InstantPot Wikipedia page has a list of models. I'd avoid the ones with airfryer lids. iFixit has a handful of guides for disassembly and repair of a few multi-cooker models including the IP.

Not actually me, but in the middle of a raid when one of two brothers in the raid force suddenly typed "Got to go, yacht sinking" and they both logged out. (Not a terrible reason though)
