Customer Ratings & Reviews

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?

Very good product and works great, easy to use and worth the money for any one who would like to enjoy their drink for a longer time, or someone who has a lot of multitasking

Bought this as a gift for a family member for Christmas, and the recipient really likes it for their tea. It is very well insulated on the outside so you don't burn your hands holding the mug like some others. Only complaint is that the battery life isn't the longest, but I saw that the lid you can buy may extend it to a certain extent, so that may be worth a try.

Excellent - works as expected. Keeps coffee the desired temperature for as long as I need

works as advertised, perfect during the cold months to keep the coffee warmer a littler longer!

Great cup! Keeps my coffee hot for at least an hour. Easy to clean

Bought this for my friend who loves coffee, she fould it very easy to use and loves how you can adjust the temp on the app

Love these things. This is my fourth one and I've been happy with all of them. They are great if you're not the type to drink your coffee fast, they keep it warm for a couple of hours, or all day if you have it on the charging coaster. I highly recommend them. A little expensive when not on sale though

Nice product. Keeps coffee hot as advertised. I thought the battery would last longer though. It only lasts an hour, maybe a bit longer. Overall I am happy with the product.

beautiful mug! Love the color. The temperature control is perfect!

Christmas present for the Wife. She has been wanting one for a pretty long time. Seen a few reviews showing that the interior coating coming off and my only guess for the reason for that is that maybe they used a frother. Anyways this only gets hand washed and it is performing like an absolute champ. Do wish that they had a 20oz that was not the tumbler though.

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.

So far so good. Wish the maximum temperature could be set to 155 as 145 is just about warm for my taste. I was debating between 10 and 14 oz due to additional cost. But ended up going for 14 oz and glad that I did. 10 oz would have been too small and require frequent refill. You might as well heat in the microwave on refill visit. 14 oz also carries perfect amount of heft and feel. You know you are holding something good with or without your tea or cofee. That said, be careful while washing (handwash only) as the contact points (the two circular rings) with charging coaster are visible and exposed.

Ember works well. Maintains a consistent temperature. Only complaint would be regarding the length of time the cup is able to do so.

Keeps coffee at the correct temperature. Battery life is a bit shorter than desired, but if on the charger it works for multiple cups throughout the day. Good investment.

I was always on the fence about getting this mug but after getting one I do not regret it. There are plenty of times I was unable to finish my morning latte and I would just end up drinking it cold or like warm. But after getting this mug I can now enjoy it warm all the way until the end.

My wife has a home office set up with a mini fridge and coffee maker, and when she’s home working, she spends hours on video conferences, and when I happened to drop in on her, I noticed her coffee was often left sitting on her desk partially full. I know she likes hot coffee so I surprised her with this so her coffee will always be hot, and she is thrilled with the results, saying she never realized how much she missed having a hot cup of coffee during the day.

Love that it keeps my beverages warm. Easy to use and keep clean.

It's a completely unnecessary product and far more expensive than it's worth, but still, I use it every day and love it. It takes me a while to get through my daily hot beverage and either poured out the last bit or just took a big swig to finish off the cold remains...but with this my drink stays the exact temperature I want down to the last drop. The 14oz is a little inconsistent in the temperature sometimes...the bottom of the cup can have the liquid a higher temperature than the top depending on how long your drink has been sitting. It's a big mug and exposure at the top since it isn't sealed seems right.

It was a great gift! Keeps everything warm and is very easy to use.
