Customer Ratings & Reviews

I am so please with this mug. I thought it would be similar to the electric cup warmers but so much better. I work from home and at times get distracted, when I return to my coffee, it’s cold. Not this one, it remains at temperature I set. If I have to run out I can carry and it’s the same temp as I set. Saves from wasting coffee throughout the day because I let it get cold.

The ember mug exceeded my expectations. The mug feels high quality and looks really nice as well. It keeps my coffee just as hot as I poured it till the very last drop. It cleans up well, the app is simple and easy to use, and the charging feels futuristic. I would recommend this to anyone who hates when their drinks get cold, this is the perfect solution.

Got this as a gift from my husband so I would stop leaving my mug in the microwave. It is great, I love that I can set the temp I want on the app and take it with me around the house or the office. PS don’t tell my husband, sometimes I forget to put it back in the charging base and my coffee gets cold anyway lol

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 like the design and comfort of the handle. The flat design is the most comfortable for holding/gripping the mug.The lip is not thick also. I've had no problems with the app. Too bad the battery only lasts 1 1/2hr. before charges. The price is a bit excessive, but Im keeping it.

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).

In general wonderful! I sit at a desk for long periods and this will keep coffee hot for well over an hour. The only problem, is that its almost too hot. I know there is supposed to be a way to control temp on the app...I'll have to look into that. The button on the bottom is a bit touchy but it works.

This is at once, one of the best and worst products I've ever had. The concept is 100%. I can't tell you how glorious it is to have the first sip of coffee be just as hot as the last sip. Brilliant! I love it so much. The mug itself is a solid 90%. It feels good in the hand. The handle is decent. The battery life is not bad, and is greatly improved by the accessory lid which is an additional fifteen bucks or so. However. The coaster is an absolute cluster of a design fail from start to finish. They break like crazy, and cannot be easily repaired. Without a coaster, you cannot charge the mug, making the entire thing useless. They do warranty it, but dime to a dollar, your coaster will break 2 weeks past the warranty period. So, in order to charge your very expensive coffee mug, you will need to lay out an extra forty bucks to buy another coaster every so often. So an expensive mug becomes a VERY expensive mug, because of this horrible design by Ember.

[Employee of bestbuy] The Ember Mug is a great gift for anyone anyone who enjoys their drinks to be hot, and to stay that way. They provide you with a nicely-sized cup which not only comes with an app to customize & set your own temperature, but it also has built in thermal technology to keep your hands safe & store all of the heat inside.

I bought this Blue model on sale to try before getting another as a secret Xmas present for my Daughter. It works as advertised and I am extremely happy and my Daughter says "best present ever" as she works 2nd job from home at desk for hours at a time. The initial 135 degree setting I thought was a little too hot for my taste but I have gone back to it after trying 125 degree recommended by some Coffee guides. Initial setup for the App was okay but not intuitive that you must actually follow a few extra steps even though the prompts are already saying press "here". It is best to manually sync the cup in your phone's Bluetooth first before trying to follow the App. After that go slow and let the App sync until it gives you the menu. I only used the App to change the temperature and it is not required to keep that setting. If you are going to move the cup from your Coffee Bar/Kitchen often it is best to have a 2nd charger base just to not have to walk back for a charge if you are holding a cup for long sessions in another primary room. Following guidance to not use metal spoons and non-abrasive cleaning and no issues yet with the interior coating after 4 weeks of use.

I tooked off a point because it needs to be recharged after about 1.5 hours

I love coffee. I love this mug. Love to drink my coffee from this mug. It keeps your coffee warm. I have had my mug for about 7 months and this is the only cup I use. I use a single serving machine with pods - coffee is not the best but it is convenient. One of the negatives is the coffee doesn't get hot enough so when drinking from a regular mug it cools down quickly. the EMBER mug solves that problem. So, now I can savor my coffee without trying to gulp it down- no need to reheat in the microwave. The only downside is it can take some time to recharge. I forgot to put the cup back on the charger after washing it and was so annoyed at myself when I realized I would have to use a regular cup. Always remember to place the cup on the charger after cleaning so it's always ready. the copper color is really pretty

Love the Ember cup. I can have my coffee stay hot for hours! The only downside is the app. It is horrible. Can't pair with cup. Can't personalize. Thank goodness the default temp is 135 degrees, otherwise my coffee would be too cool for my taste. If I could give Ember my review - and I've emailed them multiple times - FIX THE APP!

I gifted this to my mom. The activation and usage is easy once I've set it up for her. All she has to do is press the wanted temp setting on her phone app and it'll start working. Time to heat to desired temperature is about 5-10 minutes. My only dislike is how fast the charge gets depleted and the constant need for charging.

Awesome for someone who likes their coffee hot! Saving a lot of wear and tear on the microwave! If you drink coffee through the morning, it's best to use the recharging stand as a coaster, since the battery lasts about an hour and a half. Highly recommend.

My husband is a slow coffee drinker and was always have to reheat his cup. This ember cup has been a great solution. I recommend purchasing the larger cup if you are using a Keurig type machine.

My wife takes a long time to drink a cup of coffee and she doesn’t like it when it’s warm. This cup keeps her coffee hot for as long as it takes her to drink a full cup of coffee.

Got this on sale for $99 and it was very nice. Great construction however if you are a huge back-to-back coffee drinker, you may want to consider that the battery life is about 80 minutes and you may want to purchase multiple bases/lids for it. Great concept though! Wish the battery was a little bit longer, but for how light the cup is, I can’t complain.

This is the 2nd Ember I have bought for my wife and she loves it. The first one lasted 4 years with daily use. This one is slightly larger than the old model. The Ceramic outside feels great and the coffee always stays at the desired temp.

I love this mug. So much so that when I saw it on sale I bought an extra one in the 14oz size for the house. It’s my go to for tea, coffee, and sometimes soup. I recommend finding a temperature you like and setting it there. Once that’s done you pretty much never need to use the app if you don’t want to.
