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.

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.

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.

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

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!

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.

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.

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 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.

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 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

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

Great for the winter or every day use! Don’t you hate when your coffee or tea gets cold, well you don’t have to worry about that anymore if you get one of these. The charge is great and it keeps it at a great temp

Great Mug! Great design! Easy to use interface! Would highly recommend to anyone.

I got this for my wife for Christmas and she can't get enough of it - she uses it for almost everything and it keeps drinks hot or warm for indefinite periods of time, so when you're running around in the morning you don't have to worry about your coffee going room temperature.

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!

Valentines Day gift and absolutely love it! I generally pour a cup of coffee at the beginning of a call and sip throughout. The problem is that it is always cold by the end of the call. This keeps it warm all day on the saucer and if I am away in a separate room, up to 1.5 hours off the saucer. Perfect for the busy executive schedule.

Great concept! But if you have a few sips of coffee left in the cup, it does tend to taste burnt, and it creates a strange film at the top of the liquid. BUT - If you have the mug more than 1/2 full and leave for 20 mins or so, the beverage does stay nice and hot when you get back...

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
