Customer Ratings & Reviews

Bought this as a present for my mom for the holidays and she's over the moon for it. Keeps her coffee the perfect temperature for hours off the base and all day on it. Great product.

Keeps your coffee warm for hours! Great design and sleek look.

Excellent gift for coffee lovers, Bought this for my sister and she loves it

This is everything that it says it is this cup is so amazing keeps everything warm and I loved it so much that I gave them as gifts at the office

[Employee of bestbuy] This is my second time purchasing this mug because they are just that great! I’ve had my first one for a couple of years and it’s going strong, this time i’m gifting one.

This is a wonderful item for someone who enjoys slowly sipping coffee or any warm drink. Easy to set temperature, and works plenty long enough even if not sitting on charging pad.

I am really enjoying this mug, as it keeps my coffee warm. Plus, the mug and coaster look lovely on my desk.

You are not you when you have to drink your tea cold. This mug has never failed to keep me happy and warm enough to thaw a frozen heart. You will never be cranky again! Only slightly disappointed in the fact that the battery lasts 3hr. But if you are constantly at your desk it really doesn't matter.

I absolutely love this coffee mug!!! I can take my time and enjoy every hot sip of my coffee! Great because i get really busy at work where i have to come back to my coffee and love that it is always warm. Never have to worry about my coffee getting cold!

Great! No cold coffee again. Very useful and easy to use.

Bought this as a gift and it work great and is very easy to use

Bought this for my wife. She loves hot drinks, but the tumblers usually keep the drinks too hot for a long time and regular ceramic mugs do not keep the drinks hot enough. This is perfect for her because she can keep it on her desk as she works and keeps the drink at the perfect temperature.

[Employee of bestbuy] My mother LOVES this cup. She is messaging me weekly telling me so. Sje loves that she does not have to drink her coffee fast (while its warm) or keep running to the microwave to reheat. I purchased gsp, just in case.

Excellent gift for the coffee junkies in your life. They will love you

If the cup is not on the heating element, then it remains the right temperature for about 75 minutes. Otherwise it it not very different from the old fashioned plate warmer for regular ceramic cups that is switched on and off but the cup needs to be on the plate to keep its temperature. This Ember cup is not dishwasher safe.

Nice solution to a problem I didn't know I had. I like not having to deal with cold coffee anymore. After washing and charging the mug, there's a small ring of water on the charger base no matter how carefully we wash and dry it. Hopefully, this won't cause any issues with the life of the mug.

This product works exactly as described but it will eventually create a ring around the inside of the mug where the heat eminates from. This is my second mug and I’ve enjoyed the product. My grandmother also has one and swears by it.

Bought this again wore the first one out after 5 years pretty good life so this time I got the stainless !!!

so far, I love it. I haven't had the time to play w the app and figure it all out yet. so far, so good though. I find that it keeps my coffee warm but not hot. I am guessing there's a way for me to adjust the temp using the app. I just haven't had the time to play with it yet

This mug outlasts your back-to-back meetings! No more ending your conference calls and going back to a cold cup of coffee. Easy to clean, maintain and charge. Have had this mug for 5 months now with daily use and have not encountered any problems whatsoever. Love this mug!
