Customer Ratings & Reviews

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

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!

Best on the market ordered cup different brand with right back to my ember

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.

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

As the owner of both the black original and now the stainless steel version, the latter is my clear favorite. It does the same thing as the black, but it looks cooler doing it.

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.

It’s great for morning coffee! It keeps it at the perfect temperature for me. I love it!

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!

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!

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.

perfect design, easy to use, introduce to friends, everyone is happy! it's also the best Christmas gift!

I love this mug and coaster/charger. It is a great invention. My only concern is the size of the cup and the price.

I bought this for my mom who loves coffee. She really likes that it keeps the temperature you set it at for up to 90 minutes on one charge off of the base. You can control the temp you want your beverage to be. Also if there are more than one in a home same color you can customize your light on cup so you know which one is yours, overall a really great product.

If you're a serious coffee or tea drinker and you like your drink to be consistent on temperature, even if you have to walk away from it for a period of time, you must have this mug! It works so well to keep your drink at a constant temperature and preventing it from getting cold and gross. My wife loves her multiple cups of morning coffee and she gets excited every morning to use her Ember.

Love having hot coffee all morning long easy to use, perfect for all hot beverages. Perfect for my at home office.

I bought this for my husband bc he works from home and always leaving his coffees to sit and get cold. He didn’t ask for it, and kind of gave me a weird look when I gave it to him, but now he’s a total convert. He’s in love. He uses it everyday, all day, and tells everyone about how great it is. The only thing is that he fills it to the brim when he pours out of the keurig. I probably should have gotten the next size up.

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.

This was Purchased for my Wife for Mothers Day. She Loved it. Very Easy to Set Up. AND IT ACTUALLY WORKED

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!
