Customer Ratings & Reviews

My wife, son and I each have one of these. They are fantastic! No more getting up in the middle of a cup of coffee just to put it in the microwave just to heat it up. A little pricy but worth every penny. I'm thinking about getting one more for the road. Best Buy had to do a little scrambling since one was out of stock locally. They found one in another store and it arrived one day later than the other two. They also kept me informed of what was happening and when I could expect it. Fantastic product and fantastic customer service!

Great product and a great Christmas gift or any Coffee or tea drinker. I wouldn't want to give this up now that I am used to hot coffee!

I got this om a whim cuz i like gadgets. But it does keep my tea nice and warm at various temps as long as there is liquid in the cup. There is a tea timer in the app which is nice touch. Even tho you can color code it, i’d prefer to just name them. I have two of them.

Works as well as advertised. Keep in mind that you do not want to leave the drinks in there for too long as you are essentially cooking your drinks. They will develop some strange flavors after enough time. The app works fine, but the mug is completely unusable without it which is a bit of a negative. Also a tad expensive for what it does.

Works as advertised. Battery lasts only for 30 mins and this version i bought can’t hold that much liquid. App is a little wonky too

The perfect gift for the coffee drinkers in your life. Easy to use, easy to clean and provides a clean design throughout.

My husband and I are serious coffee drinkers, and had recently taken to nuking our coffee to keep it hot enough. These cups were an extravagant gift to ourselves and we're thoroughly enjoying them. Our experience has been great, up to and including using the Android app to control temperature and a couple other features. Very pleased. I've ordered another so that I can keep one cup charging while one's in use -- again, very serious coffee drinker here.

Got for my daughter who always likes her coffee hot while she's drinking a few cups during her work meetings. She loves it! So I decided to get one for myself BUT I use a Keurig coffee maker, always making an 8 oz size cup--problem is I like a lot of cream so I realize the 10 oz cup will be too full, need to get a 14 oz Ember mug! Hopefully it will be on a Deal of the Day soon!

Love the design and finish of this cup. High quality and saves me trips to the microwave.

It works well. Warms drinks nicely. Good Build Quality

The Ember keeps my coffee warm for at least an hour, which is the longest I have taken to drink a cup. Probably will last longer. However, 10 oz probably means up to the brim, and you wouldn't be able to drink it without spilling. But for 8 oz, it's great.

I’d initially purchased one for my wife who’s a daily coffee drinker. After she used it, she purchased one for me for Fathers Day and I’m so glad she did. Getting early morning coffee Mon longer requires multiple microwave reheats be sue the cup really does keep the coffee nice and hot! I highly recommend this this one!

It is amazing. Keeps beverages hot for an extremely long time, never have to reheat

Great value, nice color and keeps beverages hot at a temperature selected. I wish they would come on a larger sizes

This is the best gift I ever received for my morning coffee at work. Coffee typically gets warm, then lukewarm, then cold as I take too long to drink it as work mixes with my coffee time. Ember solved all of that for me. My coffee stays at a consistent 135 degrees through the entire cup regardless of the time frame. It’s the best!

Looked at this cup for a while before actually purchasing. Thought it may be another gadget I picked up or novelty would wear off. It was on the deal of the day and I took the plunge. Now, I'm about to buy the 14oz. I use it everyday and love it. I can walk around with a cup of coffee and it truly stays hot. If you're used to using the larger setting on the keurig or like a larger cup of coffee, I would suggest buying the larger size.

I love it. I wish the charge lasted more than 2 hours however, realistically it's rare that I am still drinking it by then but if I do I keep it on the charger at my desk. You have to be careful not to get the bottom of the cup/charger wet but otherwise I have really enjoyed it.

I got this for my wife for Christmas. It's amazing how much of a difference it makes when your coffee is continuously at the ideal temperature. Sure, it seems like a lot to spend on a mug and it certainly isn't for everyone, but any coffee aficionado will love it!

Very simple to use and is easy to clean! It also can warms up drinks pretty quickly

Excellent gift for coffee lovers, Bought this for my sister and she loves it
