Ember Temperature Control Smart Mug² - 10 oz | $90 | 31% Off | Best Buy
Cold beverages that are supposed to be hot are kind of a nightmare. You’re not drinking cold brew—you made that brew hot, so keep it that way, you know? The Ember Temperature Control Smart Mug lets you choose how hot you want that coffee using Ember’s app. You can keep that mug hot all day using the charging coaster—or just for 1.5 hours without. Because it’s thoughtfully designed of ceramic and stainless steel, you’re supposed to hand-wash this mug—and obviously, no microwave needed since it heats itself up. It’s a great gift for the hot tea drinker, or for sipping through the holiday season.
