Customer Ratings & Reviews

I need to start by saying I love these mugs. I love having steaming hot coffee from beginning to end. That being said they have one major caveat. These things break apart inside and they don’t last long. The bottom flakes off. Always stirring the coffee in a different mug before putting it in here and rinsing right away doesn’t seem to help. They make a stainless steel tumbler that’s a thousand times better. We’ve switch to those and have had no issues.

I purchase this for my coffee-drinking girlfriend. She is a slow coffee drinker and has to reheat her coffee in the microwave several times each morning. I thought this would be the perfect gift, and she loved it. It works exactly as advertised. The cup stays warm and there is no more use of the microwave for this task.

nice color and works well. keeps hot coffee hot. only downside is the battery is not as long as the 10oz version.

Bought for my wife and she loves it. No more cold coffee!

This mug is AWESOME! My wife never finishes her coffee on the first go around. She always has to heat it up in the microwave later on. I purchased this mug for her and now she never uses anything else. This keeps ANY beverage hot and always ready to drink

These are great, wife loves them. Her last one lasted several years before it wouldn't charge anymore.

I received this as a holiday gift and wasn’t sure how often I would use it. Then I got my seasonal cold and it is a lifesaver! The app is great as I can track and set the exact temp of my tea. The cup knows when it’s empty and shuts off!

My first purchase was 2 years ago. My other half loves it so much I bought another for our friend and office.

Ok so a lot of reciews of these come from people wirh unrealistic expectations. It does everything that it is advertised to do. If you want something warm 2+ hours in great condition after you make it? Put it in the mug, and leave it on the charger and you have hot perfect beverage almost forever.

This mug is great. Now my wife or I can have our coffee and chase our kiddos around without worrying about drinking cold coffee. Keeps the coffee hot for over an hour.

What a great cup. I love how well it keeps your drink warm while you are busy.

Works great and very easy to use. Wish battery wouls last longer.

I love this coffee mug. It keeps my coffee the perfect temperature throughout the day. I bring my coffee to work in a Contigo and it does a great job keeping my coffee hot until about lunch. When I hit my afternoon circadian low I put my coffee in my Ember mug. Perfect temperature coffee in the afternoon. The only down side is the battery only lasts about 30 min. I leave it in the charger until it reaches temperature and this helps the battery last longer.

A welcome addition to my office. I no longer need to bring a travel mug to my desk. My coffee or tea is kept at the temperature I like. It also has a nice feel in my hand. It even has a timer for my tea. No more wasted cups of tea and coffee.

I love this cup. I have my hot coffee through my one hour and a half of study every morning I’ve bought through two others and I’m considering buying more for all the people I love.

It’s my second mug. I like them but battery time is limited to one cup.

Great buy! Keeps coffee at perfect temp, throughout drinking it!

There's nothing quite like going back for another sip of my coffee that I made 30 minutes ago and have it still be at the perfect temperature. I've had this for about a year now and I am in love. You can't go wrong with an Ember mug or tumbler

Bought this for my mother for Mother's Day. She uses it every day and absolutely loves it! Still thanks me every time I stop by and raves about it.

I bought this after I noticed a friend had one. I am a tea drinker (especially in the winter). This cup is great for keeping drinks warm. I like that you can adjust the temperature as you like. There are also preset temperature recommendations for specific drinks.
