Customer Ratings & Reviews

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.

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

My Wife simply LOVES this Tea/Coffee cup. the technology behind this is simply amazing. No more aluminum foil to place on top of her cup to keep the heat in. she simply sets the tempter using her bluetooth phone and it remains that temp till the drink is done. A little expensive but worth it.. PS I purchased another one for my sisters birthday present.

I already have a mug and a travel mug. These are the best cups i have found for traveling, at my desk or just lazy afternoons. I even bought a few for gifts!

Purchased this for my wife for Christmas. I know she’s going to love this gift!

Maintains a fairly accurate temperature the size is not too big and bulky. It’s a little pricey, however

My husband drinks coffee everyday and has a ton of mugs. I took a chance, and it was a hit. He loves the mug and doesn’t waste coffee because it’s stays hot longer. He loves the app, he’s such a techy.

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

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!

An interesting, but not necessary device, I never have a cup of coffee sit long enough to get cold, but ny wife does, The cup size could be larger. A bike purchase for folks. Who let their coffee or tea sit for extended periods of time, I am not a fan of the trend of having to use an app for everything (But you can use the mug without the app.)

Got my husband one for Christmas! He loves it! It takes a bit of time to charge, but he uses it a lot. Keeps his coffee warm and he doesn’t miss heating it up frequently.

Love this mug. Keeps me from reheating my coffee and tea over and over. Would definitely recommend for other busy moms and dads who dont have time to drink a hot cup of coffee.

My husband lives in Nigeria where sometimes they won’t have electricity because of government placed power outages. Now he charges his cups of coffee that stays hot for hours.

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 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.

Bought this for my huband who was always microwaving his coffe to warm it up. He really likes this mug and had no trouble using the app to increase the temperature.

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.

It was a Gift for my wife. She wouldn't part with it now.

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.
