Customer Ratings & Reviews

I was worried about the day I would eventually drop the mug and possibly watch it shatter. Well that day finally arrived, yesterday, dropping it directly onto my concrete driveway from about 3'. I saw it hit, expecting it to shatter, but it didn't! Still fully functioning with only a couple small scratches. I thought it was ceramic based but it appears to be metal, maybe aluminum, by looking at the scratches.

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

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!

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

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.

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.

It does work, but it’s not something that will stay charged long enough to use all day.

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 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!!

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

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.

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!

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

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.

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.

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

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

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

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.

I got this mug for my wife for Christmas and she loves it! The app works well and it keeps her coffee nice and hot all day long. It's easy to clean and very solid. Great buy!
