Customer Ratings & Reviews

Finally, my husband can enjoy his coffee at the perfectly desired temperature! He’s been looking for the cup that keeps his coffee hot with little success until EMBER came into his life. A game changer indeed!

No more sipping cold coffee or tea. This is the perfect size for those who use a Keurig to make their coffee, there is enough room left in the mug to add creamer if prefered.

Best thing ever for a coffee drinker! I like the Ember mug so much that after buying this one, I bought another to keep at my desk at work. Prevents me from tossing out my coffee after it gets cold on me.

Love it! Super convenien. Love the app. Works well.

Great product. Definitely keypad the perfect temp. Battery could last longer for the price.

I bought the cup for my wife as a gift, and she loves it. She poured room temperature coffee into the cup and it heated right up to her desired temperature. Keeps hot coffee warm and has adequate battery life.

I bought this mug as a present for my son because I already got one and I love it. I like my coffee hot and the mug has been the best solution so far.

This was the best purchase i ever made. My coffee was constantly going cold after i make it and have to care for customers. Now it stays hot to the perfect temp all day.

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

I bought this mug as. A gift because I’ve had one for three years and I have had zero problems. It keeps your coffee or tea nice and hot (or warm if that’s your preference) for hours! I find myself sipping on the same cup for a long time because it never gets cold! A Must Have!

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.

Great cup it keeps my drink hot for awhile the only issue was it didn’t have a lid if I wanted to run out with it but I got the separate lid for 14 dollars and it works great and looks nice on my kitchen

This mug functions beautifully, when it stays connected to my wife's phone. Occasionally, perhaps when it updates, it creates a problem to reconnect to her phone. It still works, but not fully functional until I can get it reconnected.

So from the standpoint of keeping my coffee hot this is an awesome mug and I love it. The downside is buying it in white…there is no way to keep it sparkling white but it’s great and I use it nearly every day. It’s also a little pricey…find it on sale if you can.

This is the best coffee mug ever invented. It’s keep my coffee at an optimal temperature for 30-45 minutes which is more than enough to drink a nice cup of coffee or even have two. One of the best investments my wife has made for me our entire marriage

These Ember Temperature Control Smart Mugs are just awesome! It is soooo nice to have my cappuccino stay hot, just right! It's like magic! I love these things!

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

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

Works great to keep my drinks hot. As a new mom I find that every time I make a coffee or tea, by the time I go to take a sip my drink is cold. Would recommend
