Customer Ratings & Reviews

Works well keeps drinks at my desired temperature. Also battery lasts long time.

Saves about 20 trips per day to the microwave. (almost) Only downside is my husband can no longer warm his hands on his coffee mug. However, he can get through a whole meeting without running to warm his coffee up. Clever product.

Works great. Keeps coffee at the perfect temp for as long as it takes me to finish!

if you read the instructions, this mug is the best! Kept my coffee hot for a long time, no microwave!

Love how I am able to adjust the temperature and it us so simple to understand

This item performs as advertised, but there are significant drawbacks for me. The instructions say not to put it in a microwave. I use refrigerated creamer, which I typically warm in the microwave in the coffee mug. With the Ember i have to use two cups. I also find, like most coffee mugs, that it is best to warm the cup with hot water before using it. This product is not worth the cost.

My son received this as a Christmas gift. He is absolutely thrilled. It is perfect for him since his work involves constant interruptions and his coffee never stays hot. This is the perfect solution.

I absolutely love this cup!! I am a slow coffee drinker so my coffee usually gets cold before I can drink the whole cup. This amazing gadget keeps my coffee at the perfect temperature .... right to the very last drop!

Love this cup! I can set the temp to my liking. Only drawback is I drink coffee ALL day and the charge doesn’t last long enough.

Love this! Nothing better than keeping the coffee hot yet at a drinkable temperate. I use mine every morning, and it is hot until it's gone. Makes a get gift too.

GREAT! keeps liquids warm for a few hours. If you put jell-o inside it will liquefy it in 10 minutes. The BAD thing is that i just saw some of these knock-offs at walfart for 39$ in 120z too.

Ease of use (of accompanying phone app) exceeded expectation.

I'm a really slow coffe drinker and this mug is great at keeping mine warm till I'm done.

Does exactly as expected. Keep hot beverages hot, i mean really hot, all day long! Perfect for long Zoom/Teams meetings.

Got this as a gift for my wife and she loves it. Seems like it works great and keeps her coffee at a good drinking temperature. Would recommend, especially if you can get it on sale.

Keeps coffee nice and warm. Battery life is alright but can use a upgrade on next coffee model

This was a great hit for my Boss. He is an avid coffee drinker and this keeps his drinks hot throughout the day. A happy Boss a Happy Life. LOL

This was a Christmas gift for my daughter who spends long hours sitting at her desk and she absolutely hates cold coffee! This is just the ticket for her, she loves it and the color is the best!!

For coffee lovers, that drink coffee 24/7 is the best gadget outhere. It has an autonomy ( without plug more than 2 h ) and keeps your coffee on the right temp. It is a little pricey, but totally worth the money.

Great cup! Wonderful at doing its job of keeping hot liquids hot. Would highly recommend.
