Had one of these today at my cousin’s house (she recently got a Keurig). I figured ‘d give it a shot, plus it’s fun to use the little cups. Up front, I hate all the waste involved but it was a novelty. Nothing special about the tea, fairly standard ‘bagged’ fare. Didn’t get too bitter, but probably because it didn’t seem to reach boiling. Totally do-able in a pinch, and pretty neat!
