Customer Ratings & Reviews

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.

Awesome job of keeping coffee hot - just expensive

I love this Mug so much, I've purchased 3 of them over the past two years (2 for me; 1 as a Gift). If you take hours to drink your hot beverages, do not hesitate to purchase this. While I wish the Battery would last longer (approximately 70-80 minutes for preferred temp of 145 degrees), I can't complain about anything else. Looks great next to my Starbucks Verismo machine as well.

Bought this for my wife as valentine's day gift. We are very picky on our coffee in terms of the process its made and freshness so we usually make our own coffee at home. Using this cup has elevated the flavor since it retains heat for the duration of the drink. I want to buy another one but the price for it went up from $150-180. Got to wait for a sale on this...

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

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.

My husband loves this mug! Keeps his coffee and tea at the perfect temp!

Before my Ember mug, I used to have to reheat my coffee in the microwave -- sometimes more than once. No more! I love the comfort of warm drinkable coffee, and this allows me to set it just how I like it, and keep it that way while I'm working and sipping on it. I'm going to buy a second one for the office.

Works very well but the price is quite high. Keeps liquids at temperatures I like.

I wish I knew about this along time ago. This keeps my coffee warm at the temperature I set on my phone app. The secret benefit is that it warms up my coffee after putting cold milk in it. My only wish, besides a longer charge, is a larger 16 or 20 oz size. A 14 oz mug means 14 oz without the milk, syrups, etc.

Love my ember mug! Coffee and tea stays nice and hot!

Never knew I needed this. My husband complained we were wasting money because I used to only drink a half a cup of coffee when my coffee went cold. We use Nespresso vertuo capsules. Not cheap. However, he bought me this as one of my gifts for Christmas. But we’re not really saving money because now I drink two full cups of coffee a day. But hey at least I’m not wasting money!

Keeps my coffee hot and fresh. I love the ease of use as well!

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.

Bought as gift for wife and I’ve heard nothing but great things about this product. She loves the fact she can control the temp from the palm of her hand and don’t have to worry about other means to keep it warm.

Cool idea. Battery does not last all day. It holds a good amount of coffee and the 10oz cup is too small.

This just works. Coffee stays hot, no temperature fluctuations. It feels solid and has a nice weight. I invested a little more and bought a second charging coaster so I can easily move from room to room. Is this a ridiculous price for a coffee cup? Yes, it is. Is it worth it? Yes, it is

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!

Christmas present for wife and she loves it. Keeps coffee warm during entire workday. App is a little useless but fun to control. This does include a charging pad. Hand wash safe too. Definitely go with the larger oz size if the price is right, 10 oz is not enough these winter days in northern Wisconsin.

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.
