These things are great. My wife and I each have one already. So this was a gift for my father in law. You can take your time and enjoy your coffee instead of trying to scarf it down before it gets cold. Can even enjoy it out on the deck when it’s a little chilly outside because it stays hot. I keep mine at 128

I'm writing this for a chance to win a $400 gift card lol Cool cup, though

Love my Ember mug! my coffee is always hot! Never again will i drink luke warm coffee!

love this cup, keeps coffee hot. I love the new size too.

Great mug! Keeps the coffee warm. The size was great.

There is nothing like a nice cup of coffee - no matter how long it takes me to drink it! The app to manage the cup and its temperature is very easy to use, and the battery lasts about 80 minutes on a full charge. It's more than a nice to have, it's a must-have!

Keeps coffee hot! Wish it would last just a little longer and was a little less expensive.

Great mug and does the job, just wish the battery lasted a bit longer.

Worth it if you drink a lot of coffee. I no longer need to chug it down quickly to enjoy it hot.

I like this cup. It looks nice and funtions perfectly. But the battery just doesnt last long enough and it takes a while to charge. If youre the type if person that drinks coffee all day, maybe get a thermos. If you just have a cup if two for breakfast. It works well.

Keeps hot drinks the perfect temp, works great for coffee and tea. Easy to keep clean and use.

I was reluctant to buy this mug. I have been looking into getting one for a few years. Once the 14 oz version came out I was even more interested. So far the Ember meets and exceeds my expectations. It is great to have a hot cup of coffee all the way to the last drop. It was even a little weird to not have to drink cold coffee on my last sip. I have only had this mug for a short time but I am very pleased.

My second Ember mug and this one didn’t disappoint. Simple to set up and connect to my Apple iPhone. Keeps beverages a set temperature without a struggle. No more throwing away cold coffee or needing a “hot top”. Worth the price.

I Purchased this item because I’m on zoom all day and drink a lot of coffee. I would make a carafe and microwave each mug full to make it hot before drinking- reheating often if I didn’t drink it fast enough and it got cold. I thought this mug would be the PERFECT solution. Here’s why it wasn’t: 1- I always started with hot coffee (pour over coffee) brewed directly into the cup. Although it kept the coffee at the desired temperature, the mug lasted an average of 45-50 minutes when it was advertised to last about 2 hrs. My average meeting is 90 minutes. 2-the mug took too long to recharge, so I took to keep it in the base (plugged in) whenever I wasn’t drinking. Even though I took sips often, it would still go into ‘sleep’ mode, the coffee would get cold and I’d have to restart the mug again and wait several minutes for it to get hot. 3- sometimes it wouldn’t restart… and I’d have to exit zoom to look at the app, which would show “empty” even though the cup was more than 1/2 full. So I guess it’s not good for continuous use. It did these things so often, I returned it. So I'm back to nuking my coffee when it gets cold. It’s a hassle but it works… and it doesn’t cost $120!

I love this mug. I drink coffee slowly at my desk so it keeps it hot in between sips!

I like to drink my coffee hot, and my 14 ounce temperature control mug keeps it perfect for me!

This is the larger of the two Ember mugs and the seemingly slight difference in size is worth it. I had the smaller size for awhile and really liked it, but eventually the inside coating began wearing away. I'm hoping this one will be hardier - it seems better at early glance at least. I admit this is a frivolous item, but I really love being able to drink my coffee slowly and not get cool.

I bought this for my wife, who is a coffee drinker. She loves it. She usually nurses her coffee and consequently had to microwave it a couple of times before finishing a cup, but not with the Ember. It keeps it nice and hot all the time.

Love this mug, I NEED my coffee to be hot when I drink it and this is the only mug that does the job. I have tried other brands but Ember is the only one that actually works. From the first sip until the last, even if it takes me an hour to drink the whole thing ( sometimes life gets in the way).

Ok...so I purchased this for my father a few years back. He uses it everyday. After how happy it made him, I was determined to buy one. Whenever I get a cup of coffee at work, I always seem to get pulled away and when I return I have a cold or lukewarm cup of coffee. Not anymore! Love this cup!
