Customer Ratings & Reviews

Great cup, it has a few quirks about charging and knowing when to charge it. The app has a few issues though.

I've wanted to get my husband an Ember mug, but he thought it was too expensive. It IS a lot for a coffee mug, but he is really enjoying the fact that his coffee isn't continually getting cold before he can finish it. We've gifted four family members with Ember mugs over the past two years, and each one of them loves to use theirs.

I got this mug for my wife for Christmas and she loves it! The app works well and it keeps her coffee nice and hot all day long. It's easy to clean and very solid. Great buy!

If you love coffee, you need one of these! It is fantastic! By far the best gift I've ever had. It surprised me how much I love this new cup. Not only does my coffee not get cold as I move around the house, even when I'm using it at my desk keeping it on the charger, this cup let's me enjoy that cup even more. All the typical changes in temperature you don't even realize you've gotten used to in a cup of coffee are just gone. I promise you'll love it.

Nice product. Keeps coffee hot as advertised. I thought the battery would last longer though. It only lasts an hour, maybe a bit longer. Overall I am happy with the product.

I love Ember mugs, especially the blue color! It keeps my coffee warm down to the last drop. I love that I can set the temperature to the level that I like. I definitely do not regret my purchase. Also, I was very impressed with how fast Best Buy delivered - next day!

So far so good. Wish the maximum temperature could be set to 155 as 145 is just about warm for my taste. I was debating between 10 and 14 oz due to additional cost. But ended up going for 14 oz and glad that I did. 10 oz would have been too small and require frequent refill. You might as well heat in the microwave on refill visit. 14 oz also carries perfect amount of heft and feel. You know you are holding something good with or without your tea or cofee. That said, be careful while washing (handwash only) as the contact points (the two circular rings) with charging coaster are visible and exposed.

Wife makes the best use of it always having her warm coffee

A nice mug, but battery life can be an issue. For me, it heats my coffee for about an hour, but for anything more than that it'l run out of battery leaving you with a cold beverage. Not the end of the world, but as long as you work within this limitation it's a fun product. Need to be careful when washing, so that you don't get a lot of water into the underside (where the battery is housed).

Love the copper finish! It cleans well and seems to hold temperature really well.

This cup not only looks great but keeps my coffee hot for a long time. Then charge it back up on the magic saucer after washing. A bit pricey but I noticed lower prices for the season.

Keeps coffee at the correct temperature. Battery life is a bit shorter than desired, but if on the charger it works for multiple cups throughout the day. Good investment.

Use the app to control the temperature. Easy to use

The bigger size is the way to go. Keeps your coffee warm and easy to use.

Keeps beverages hot! Easy charging, easy controls.

It's a completely unnecessary product and far more expensive than it's worth, but still, I use it every day and love it. It takes me a while to get through my daily hot beverage and either poured out the last bit or just took a big swig to finish off the cold remains...but with this my drink stays the exact temperature I want down to the last drop. The 14oz is a little inconsistent in the temperature sometimes...the bottom of the cup can have the liquid a higher temperature than the top depending on how long your drink has been sitting. It's a big mug and exposure at the top since it isn't sealed seems right.

Love this cup! However, I had to purchase an additional charger to keep at work. The battery life is ok if you are a 1-2 cup coffee drinker. Which I am, before I even get on the road to work but by the time I get to work my coffee is cold. After I purchased the additional charger, I would say this cup is a game changer.

Nice size. Attractive. Works well. But it is yet another electronic and luxury device. It requires careful cleaning and handling (no dishwasher, avoid getting bottom wet), and electricity. It is not for everyone. There are other ways to prevent cold coffee. That said, I use it every day.

This mug keeps my coffee warm and easy to wash. Highly recommend purchasing the larger sized cup.

Oled has been a game changer for a person who likes their coffee really hot.
