Customer Ratings & Reviews

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.

My wife’s loves this mug. It would be great if the battery lasted a little longer but fixed that by adding another base in the house. It’s great that anytime you go to get a drink of coffee it’s the right temp!

Keeps my coffee piping hot all day. Note, the rechargeable battery is not replaceable and lasts around 2 years, then the whole thing is trash. That's why 4 stars instead of 5.

Love love these mugs! I have several and have given them as gifts, easy to add to phone, keep coffee super hot

I received the Ember travel mug last year for Christmas as a gift. I decided to buy two of the mugs for my boyfriend and I to use. He loves it! So easy to set up and keeps your beverage warm!

This is the 5th Ember mug I have purchased, with three of them as gifts. They have all been a hit as gifts and I personally love using mine every day. I am a verrrryyy slow coffee drinker but this keeps your coffee or tea at the perfect temp. It may not heat up liquid from cold, but it will heat up lukewarm liquids to the perfect temperature.

Purchased as a gift and my friend loved it! Especially the color and as an avid tea drinker, he can't get enough of it. I did purchase this on sale so not sure if the color of the mug matters.

Bought for my wife as a gift. She loves it! Now coffee is still warm on the mornings the kids make it impossible to drink it immediately.

Pick the temperature that you want your coffee to be, and it will always be it! No more cups of cold coffee

Love the color! So nice and smooth to touch. Keeps my te hot. Great to have at home and at the office. Have to get one for my husband too!

Works excellent and great size for coffee to stay warm

I bought the 14oz mug and I must say it does exactly what it is supposed to do, and does it great. I was using a mug wormer that you place a regular mug on and it just wasn't doing the job well, so the Ember mug really solves that. Also, they claim the battery lasts 80 minutes, but I am able to get closer to 1.75 - 2 hours. My only real comments are that I am left handed and because the status light is only on one side, I can't see it without turning the mug around. I also wish it was 16 oz since my Jura puts out 14 oz of coffee and I have no room for creamer.

This is an amazing way to keep your coffee from getting too cold. I love the fact that I can pour a cup of coffee and sip it for much longer than a regular mug. It has a nice sleek design too!

Keeps my drink warm. Few quirks with the 1 hour battery life. White color also has coffee stains and burner stains at the bottom. Still works great after 6 months.

The mug does exactly as advertised. I get about 1.25 hrs of usage out of this using the max temperature ( I like it uncomfortably hot). App has connectivity issues but can be fixed in future updates.

Great warmer my tea. Heat lasts long and has been reliable for years

My wife loves her coffee and she loves it hot. At first we were skeptical but it does the job and does it well. Her last sips are as hot as the first ones making the entire cup enjoyable. We bought the white version and there is noticeable staining after some time. I’m not sure this will last forever like a regular mug but a great concept and performs well. The price tag could be less but if hot coffee or beverage is important to you to the last sip this is a must have.

Love this mug! Gave it to my sister for her birthday and she turned around and gave me one for mine. I absolutely love it. I like my coffee hot and really enjoy not having to drink it quick before it gets cold as I have had to do since I started drinking coffee 50 years ago! Nothing like a leisurely cup while reading. The 14 oz mug gives you enough room to add cream. Initially my sister gave me the 10 oz which I found to small.

A truly excellent temperature control smart mug, delighted to have purchased it, works great

Bought as a gift for girlfriend because she likes her coffee super hot. This goes up to 160 degrees (i think). The battery does not last long on the highest setting, so you always have to put on the charging base while using.
