Customer Ratings & Reviews

Very elegant and easy to use mug. Only minor complaint is that I wish the battery would last a little longer. I set my coffee at 137 and it keeps it hot for over an hour off the charging base.

$129 for a cup seems pretentious and expensive, but I strongly recommend it, I almost never finish my coffee drinks when they get cold, but with this cup I enjoy it a lot more, I am getting another one for office I wish they make it a little cheaper though

Purchased for my wife and she loves it. It is Elasy to use and works as advertised. A teally great product for those who don't want their hot drink getting cold.

The cup is small and it’s easy to use, but the battery life is not as long as I would like for it to be. Overall, it was a good purchase though for the cost.

Great mug. Love that it’s not hot on the outside but the drink is hot inside. It works great. I wish they made it a little bit bigger like 16 oz and somehow make it last a bit longer. But great concept and works very well. Coffee is hot till the last drop!

Got this for my partner as a gift and he loves it. Keeps coffee hot and is nice looking on the desk when WFH. Can't be run through the dishwasher and they recommend not using a metal spoon inside, just minor adjustments to be aware of if you're coming from a non-smart mug.

Works excellent and great size for coffee to stay warm

I bought this as a gift and she loves it. She keeps it at a decent temp and it lasts about an hour. For her that is perfect for others that may not be enough time.

My first Ember served well for years and I hope this one will also I like my coffee hot to the last drop.

Wonderful coffee mug keeps my coffee hot for quite some time. I like the larger capacity. Definitely prefer the dark colored mug. An excellent investment.

If you're looking for a gift for coffee lovers, search no further. The mug keeps your coffee hot for a long while and looks super sleek/modern. Just don't use metal utensils to stir.

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

Does exactly how advertised. Keeps drinks warm. One downside is that the battery runs out quickly. Orher then that product is good.

I like to size and look of this smart mug. Plan to use near charging source if plan to drink more than 2 cups away from charger, as it does not keep beverage heated for longer periods of time. Can definitely sip a couple cups casually.

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

Love the color and works great. The battery does die pretty quickly though, but you can leave it on the charger as a coffee stand.

Let's be honest - the vast majority of people don't need anything like this and it's very expensive for a coffee mug. But I'd be lying if I said I didn't love having it. It's user friendly and just works. Come back an hour later and your coffee is still at that perfect temperature without the burnt flavor you get from other coffee warmers. I do wish it used a wireless charging solution to improve water resistance, and I think a 16-18 oz size would work better. (Note that while it's 14 oz, it's really more like 12 oz of usable space unless you fill it to the brim) It's also worth mentioning that the last few sips can sometimes get much hotter, but that's just because there is so little liquid left so any heat added will jump the temperature more. Not a big deal, but a minor annoyance.

At the suggestion of my daughter, I got this for all my adult kids, myself, my sister, and my husband for Christmas. I would’ve considered it a frivolous purchase. It is not. It keeps your coffee nice and warm the whole time you don’t think you need it, but you do. The only thing I can’t speak of is how long it lasts. I also had to buy another charger and that was worth it too, just to have one upstairs and downstairs. Until you have one, you just don’t know. It’s like when the microwave came out.

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

I got this as a replacement for a 10 oz mug I purchased 2 years ago. I always felt it was a little too small for my coffee consumption. It works a advertised, but since I take my coffee with milk, the heat makes it form a skin which is disagreeable, but not the fault of the mug. I have used this recently with tea (no milk) to get me out of a cold and it has been great at keeping the temperature hot enough to soothe my throat. Hope to buy a travel mug when they are on sale, those things are expensive!
