My roommate and I used this heater in the communal space because, for some reason, our tiny apartment could not circulate the hot air enough to keep us from shivering on the couch. We spent days lounging on the couch watching Elf (the only Christmas movie that matters) and Good Girls Revolt (RIP). We couldn't have done it without this teeny tiny heater. Coziest thing ever.
