Customer Ratings & Reviews

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.

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

Works like it is advertized. Keeps the liquid hot for a long time

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?

Ordered the blue Ember mug online. Shipping only took a couple days. It works well. The app is easy to use. Having hot coffee or tea from start to finish is fantastic!

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

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!

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.

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!

I love, love, love this cup. I can't tell you how many times I get pulled away, come back and my coffe is cold. I decided to buy this cup and I do not regret it. I can come back an hout later and my coffe is just as hot as the first sip. I nolonger am throwing out 1/2 cup of coffee. Loved it so much bought one for my Sister - she loves it jst as much!!

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.

Wife loves it!!! With a 1 1/2 and 3 1/2 year olds running around all morning coffee tended to get cold and microwaved but with her new Christmas gift cold coffee is a thing of the past

Works excellently! Love the black. It made us want another one.

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

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.

Great mug keeps everything warm for hours, if you like hot coffee or tea, this is the cup to own

I brought this for Christmas for my coworker/friend. She drinks tea throughout our whole shift. Our office area is constantly cool where she has to repeatedly rewarm her tea. I thought this would make the perfect gift. She uses it daily and love that her drink stays at the temp she like. Additional bonus is it works with an app on her phone.

I bought it as a gift for my wife. She loves it. It keeps her coffee at a nice temperature.

Love this!! Keeps my coffee hot all day long. Highly recommend

This is the second ember mug I've owned. I had to get a larger one because I enjoyed it so much. Get him when they're on sale. Novel product but thoroughly enjoy it.
