The drinking vessel you use has a bigger effect on the overall experience than you might think. Our kitchen editors should know; they've rigorously tested countless coffee mugs, and the Ember Smart Mug is our favorite smart option. When fully charged, the Ember will keep drinks at the perfect temperature for up to 80 minutes, or for as long as the mug is full if it's on the included coaster, which also acts as a charging station for the mug.

The Ember mug can detect how much liquid is in it and act accordingly, so it will automatically turn on when liquid is poured in and go to sleep when it's empty. Plus, you can use the paired Ember app to adjust the mug's temperature or add presets for different drinks.

With nearly 13,000 five-star ratings, Amazon shoppers clearly love the Ember Smart Mug as much as our kitchen editors do. "I love this more than I thought I would. As a slow drinker, I had no idea how amazing it is to have the last sip be just as hot and delicious as the first sip. I love having a solution to keeping my coffee hot that isn't a thermos or hot plate," said one reviewer. "The app telling me when the mug has reached the perfect temperature, so I don't have to keep manually measuring myself, is massive."

The Ember mug also makes a great gift, according to shoppers. "I bought this mug two times as a gift and both recipients love it. It's super easy to set up and use and it keeps your coffee/tea very hot," said another reviewer. "I like that it has temperature control, so you can raise and lower the constant temperature of your beverage to fit your liking."

With the current discount on Amazon, the Ember Smart Mug is 40% off. Add it to your cart now for just $89.99, an all-time low price, while the deal lasts.
