Customer Ratings & Reviews

Love this mug! I have one for the house and bought second one for the office. Keeps the coffee at the perfect temperature.

I simply love it. Keeps my coffee and tea warm throughout the day. Thank you for such a great product and fantastic idea !

This was a gift for my father who loves it and uses it every day. Excellent mug.

I can't stand a luke warm beverage. My ideal temp is piping hot. Happy to report this really does keep it more than warm & has customizable temps. Have already gifted two.

Best in the market. By using the the device I am getting good savings on coffee. I can actually finish a cup at my work desk, without having to get up and get a refill on my cup.

No matter how much my fellow office drones like to crank up the AC my coffee stays warm!

I love the ember cup! Customizing the temp. Of my coffee was the best thing I didn’t know I needed until I got this cup!

Works great! Was initially worried about some of the reviews mentioning difficulties using the app, but so far I’ve experienced no issues. Using the mug without the plate is still recommended though, as the coffee taste seems to alter very slightly after extensive use during a single sitting

I love this cup. Now that I have it, I cant live without it.the charge does not last a long time. Thats my only gripe.

Does what it's supposed to. Easy to set up and use. Wish the coaster was a USB charger instead of a AC plug, which would make it easier for desks as if you want to use this for your day it's going to need to charge.

This has been our biggest gift hit this year. People love it and use and rave about it so much that I’m putting the word out I want one for Father’s Day. Seems a little selfish to fork over the $100 bucks just for yourself but if I don’t get one as a gift I just might.

Battery life does not last that long. Had to order an extra charging base to place on my desk.

I absolutely love this mug! It keeps my morning coffee hot when it’s freshly brewed and my dog decides it’s time to go for a walk. This mug has not failed me yet!

Absolutely LOVE my Ember mug! No more reheating my morning coffee multiple times in the microwave. The mug keeps my coffee at the perfect temp for the full 90 mins off the warmer and continuously if left on the warmer.

Love having hot coffee stay hot. Suggest buying 14oz cup, because 12 oz on my keurig fills to top, adjusting temp is inconvenient. Very expensive, waiting to see how long it lasts.

I bought 2 of these over a years time. The first seems to working OK but it is white and terribly stained from coffee. I followed instructions for cleaning but it is still brown on the inside. The second was blue and I thought that would look better being a dark color. Unfortunately the blue one would not maintain temperature when half full so sent it back. I like the idea of keeping beverages hot but it is s high price to buy. Check out its performance while you can take it back.

This mug has completely changed my life! This keeps my coffee at a great drinking temperature so I don’t have to rush and enjoy it

Such a great mug. Highly recommend it. Keeps coffee super hot and works like a charm! Great peoduct overall

[Employee of bestbuy] The mug works wonderfully without any crashing, and maintains the temperature pretty consistently.

My daughter says this was a wonderful Christmas gift! She is a nursing student and right now a lot of instruction is online. She doesn't have to worry about cold coffee while in class and she can enjoy it from a regular mug rather than a travel mug!
