I bought my JoyJolt just before Christmas and it’s been at my side ever since. I love have my favorite flavored water (a hibiscus tea blend) always at hand and I can fill it straight from the cold pitcher in the morning and it stays cold all day. I’m sure for hot tea it would do the same (:  My JJ is super easy to clean and have had no problem of mold around the straw connectors like other brands.
