Well I've very recently changed mugs because of a nice Christmas present from my wonderful brother. Namely the Nextmug from a company called Nextboom, a battery operated heated mug with a docking coaster. Not sure if I like it better than my Yeti, but I'll be testing it throughout the holiday season anyway. Which I could do better if I hadn't messed up the charging last night, duh, being old sucks sometimes.
