    Loving my Ember

    Loving my Ember! I wasn't sure I was going to really use this, since it was a gift, but I love it. I used to chug my coffee because it would get gold to quickly for me, but now with the Ember, I can take my time and really enjoy my coffee. The battery life isn't fantastic, about 50 minutes, but I do keep it on the charging coaster, so there is not need to worry about battery life. Highly recommend the Ember mug.

    My husband loves a hot cup of coffee, so this either required a thermos or multiple trips to the microwave. He loves his new Ember. Always just right.

    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!

    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 really great to keep my coffee at exactly the temperature I want it. My one complaint is the battery life, as someone who can take longer to drink my coffee (i.e. why I wanted the mug), I have to be able to set it on the charger while I'm drinking it for it not to die before I'm finished.

    Game Changer with 1 flaw…

    Love this cup! However, I had to purchase an additional charger to keep at work. The battery life is ok if you are a 1-2 cup coffee drinker. Which I am, before I even get on the road to work but by the time I get to work my coffee is cold. After I purchased the additional charger, I would say this cup is a game changer.

    My wife loves to sit and have coffee before work but I’m constantly going downstairs to reheat but not with this mug . It’s incredible how it keeps her coffee a 140 degrees for so long and I ordered a cover which makes it last even longer . She loves her cup !!
