Ember cup is super. Keeps my coffee warm all morning. Couldn't live without it.

My wife loves her cup, this is the second one that i have bought from Best Buy. She accidentally microwaved the first one (I strongly recommend you don't do this - lol). But the cups work great and the store was helpful.

i LOVE this mug! When I bought it, on sale on a app drop, I still thought it was an excessive purchase, but I am amazed. I love this and use it every day

My wife and I always fight the temperature of our coffee in the mornings. We no longer have to do that when getting distracted with the kids and their activities. All I have to do is place it on the charger and come back hours later to a perfectly hot cup of coffee... It's so awesome! Be sure to blow out the bottom since water likes to hide in the grooves (it's waterproof but just to be sure).

Good cup. Working without any issues for the last year

Great experience so far. Beautiful color and design and heating system is great.

Great mug keeps my coffee hot for hours!!!! The app is very intuitive as well!!

This is exactly what i needed. I drink slow and am constantly reheating my drinks

Pros: Does keep your beverage hot for a good hour. Cons: Bluetooth connection drops all the time. Have the biggest mug yet still feels like not enough compared to normal mugs. Need to wash immediate after use and put on charger so it's ready for next use.

I love this cup and have needed this my whole life!! I love my coffee but i get busy in the morning and sometimes leave my cup for 20 minutes at a time, coming back to not so hot coffee.. I love hot coffee and the Ember provides that hot that I love.

It does exactly what it says it does. No more wasted coffee

I love this mug. I wasn't sure if I was splurging a bit on an unnecessary item, but I have fallen in love with this mug and use it daily. No more cold beverages becuase I was distracted or forgot about it for a few minutes.

The mug does an excellent job at keeping the coffee warm. The app is a bit finicky and needs to be updated.

Works great! Keeps my coffee or green tea at exactly the temperature that I prefer for the 60 to 90 minutes that I sometimes need to drink the full cup.

Bought this as a gift for my spouse. I was highly skeptical but she really likes it. Its great for anyone who takes longer to drink the coffee or tea. The best feature however is the one that tells you your coffee is at the perfect temp. No more burning your mouth then setting it down to cool and forgetting about it and coming back to cold coffee.

LOVE my Ember mug! Perfectly drinkable coffee temperature for hours. Love it!

I've always enjoyed coffee, but I don't like it too hot, and I don't like it too cold. First world problems, I know. However, my Ember cup has changed my world. I make a cup, wait until it reaches my set temperature (128), and then start sipping it. Amazingly, my coffee remains at 128 degrees from that first sip until the last one. If Maxwell House had not already used the phrase, "good to the last drop", then I would apply it to Ember, which would be more true. This thing is worth it!

This mug does exactly what it’s supposed to do! Just keep in mind that the mug works even better with a lid which will help maintain a uniform temp, otherwise the Mug will cool a little if you’re in a cold environment. I purchased a universal mug from Amazon since it’s virtually impossible to get an ember one. For the price, you would think a lid would be included.

Awesome job of keeping coffee hot - just expensive

My husband loves this mug! Keeps his coffee and tea at the perfect temp!
