Customer Ratings & Reviews

We have two Ember smart mugs and an Ember travel mug, and we love them all. This one has a somewhat larger capacity than the original, which is nice since the bottom contains the battery and does not go as deep as you would think by looking at the cup. Great convenience for keeping your coffee warm.

These mugs would be incredible for those who make a pot of coffee for the day and would recommend it to those friends. If you are using K-Cups, you must get this 14oz size over the 10oz to make it justified (we had to get this one after purchasing the 10oz). If it were up to me, I would still make it a little bigger. Other than that it works well.

I got it for my wife and she opened the day of so I got her another one for her work and she said she used it and it almost burned her mouth so it dose keep drinks warm.

A must for coffee drinkers! I normally sip on my coffee while enjoying some kind of bread. My biggest annoyance was my coffee getting cold. This is the answer. Keeps my coffee for a warm 142 degrees. You wont regret it.

I put getting one of these off for awhile. That was time wasted. I have an entire cabinet of coffee mugs that have remained untouched for months.

This mug is exactly what I needed for work. I love coffee, but when I get busy at work it always goes cold. This mug keeps my coffee at a perfect temperature all morning.

This is must have if you are living in colder region… this will make sure the last sip off coffee taste like a first sip. Don’t worry about the price. It is a good investment.

Got this for my mother and she loves it. 2 out of 5 days she works for home and it does well with keeping her coffee warm while she is preoccupied with meetings and such. Thinking about biying one for myself

I love it so much I purchased a 2nd one a week later. Just so convenient not having to heat up my coffee with me being a slow sipper. All my other mugs are obsolete now.

Got it for my mom for her birthday and it's amazing. I love coffee and use this one more than my Stanley now because it stays hotter

This product has been perfect for my wfh situation. It helps maintain coffee and tea warm over extended period of times.

Love this mug! Keeps my drink hot to the last sip.

Battery life seems to be less than anticipated are’s 135 degrees, but as long as you’re using the coaster it’s amazing. Says not to use a metal spoon, as it would damage the ceramic coating... don’t really have a rubber or plastic spoon, so tough to mix in sugar/creme as needed.

I don't like cold coffee! I spent the money to buy this cup, in the copper color, for me and my boyfriend. Even when a repair guy kept talking about whatever, my mind was on my coffee. When he finally left, my coffee was still hot. I was very pleased.

Great coffee cup…Fast charging and easy to use with app… love it!

Bought this as a late Christmas present for myself. This mug works great for coffee and tea! Very pleased with how it keeps my beverage hot to the last sip. Works so well that my husband ordered one, too. We each picked a color so we can identify whose mug is whose.

Keeps coffee the perfect temp for hours! Can select the ideal temp you like and remains that way for hours. Also has a customizable led light in the event you have more than one mug.

It works as advertised! Use the app and set your coffee or tea hot and even tells when to pull the tea bag

This is an espectacular gift for Coffe or tee lovers. This is the 5th time that I choose this item as a gift for friends and clients
