    It's definitely not a necessity, and I wish it was a bit more reliable in terms of when it keeps my coffee hot and when it turns off. I'm figuring it out as I use it, and it's nice to come back after an hour or so and find my coffee nice and hot.

    Works wonderfully and keeps temperature . Love how you can sync it to your phone and have it set at a certain time of day and your beverage be ready for when you're ready to be on the go.

    Love the Ember! My coffee stays at my desired temperature the whole day! It is a little pricey but I think well worth it. I wish more colors were available besides black and white.

    Keeps everything warm. Does what it says it does. It’s good for one cup, so kind of sucks to refill if you drink a lot.

    I am always complaining because my coffee gets cold before I can drink it. My new Ember mug has changed all of this. I customized my coffee’s temp and it suits me perfectly. Best investment and gift I have had for a long time. So happy with this product!

    I was initially amazed, and embarrassed, that I spent this much for coffee mugs. But after using them daily we are hooked. At breakfast, even with delays while studying the newspaper or interrupted by a phone call, we can pick up our mugs and the coffee is still the correct temperature. Luxury? Sure. Cheaper to just take a glass mug to the microwave? Sure. But this is so much better! (By the way, 30 seconds in a microwave changes the flavor of coffee by extracting more chemicals from the "fines" which get through the filter)

    I got this for my wife for Christmas. She absolutely loves it! I’m not a big coffee drinker like her but tried hers out. You don’t realize how good a coffee is when it’s the perfect temperature though out the cup. I’ve since had to buy my own Ember mug. The wife says it was the best gift I had ever got her. Not sure how to take that seeing that it was just a coffee mug. But I know she is happy and me not so much. How am I ever gonna top this mug now?

    I LOVE this mug. It is a wonderful product that provides and keeps my Americano hot. HOWEVER! As much as I LOVE this mug there is a huge flaw of this mug. The battery life. The purpose of this mug is to keep my coffee hot for a long period of time… but when the battery life of my mug is like an hour, it doesn’t last as long as it should. Basically you have to keep it on the charger otherwise it will die quickly and you just have a $100 mug. So in conclusion. AWESOME product that when it has battery, works amazing. It just doesn’t last long enough on a charge!

    Ember mugs are great if you enjoy hot coffee. I have a charger and extra heater so I can enjoy hot coffee for hours. Standard mugs lasts 1.5 hours.

    I really wanted to like this mug and it's possible I got a defective one but after only 4 charges, it was not charging properly. One of the small pins on the base of the charger was not working properly. No water was ever near it, so it was a bummer for sure. I ended up getting a mug from another company and it's been great.

    Bought this as a Christmas present for my wife. It has performed perfectly for her in about a dozen uses thus far. This size is definitely worth it over the 10oz option. It is expensive for a cup, yes, but a wonderful way to keep hot drinks at the perfect temperature. I was able to get it on sale at $100, and that's the price I would wait for again.
