Customer Ratings & Reviews

I like the cup but it is a bit on the heavy side. The concept is great and it does keep my coffee warm. The coffee comes out of my Kuerig at 156 degrees, which must be about normal but the highest setting for the cup is 145. I don’t think I get the full 90 minutes of battery life with the setting at 145. It’s a great concept, I just wish it could keep my coffee hotter.

I recently purchased the Ember Temperature Control Smart Mug in blue and have been extremely satisfied with its performance. The mug has a sleek and modern design that looks great in any setting. The temperature control feature is a game-changer, allowing me to set the exact temperature of my coffee or tea and maintain it throughout the day. The 14 oz capacity is perfect for a single serving and the mug keeps my drinks hot for hours on end. The mug is also very easy to use, with a simple button interface and the ability to control it via a smartphone app. I also appreciate that the mug is made of durable materials and feels high-quality in my hand. Overall, I highly recommend the Ember Temperature Control Smart Mug² to anyone who values having their drinks at the perfect temperature all day long.

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

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

A little costly, but worth it. Now I never have to worry of my tea or coffee going cold.

I really enjoy that the mug keeps my coffee hot for nearly the entire length of tha battery life. The app was easy to pair with my phone and i love the ability to control the settings from the phone.

Works great, keep my coffe hot all the time, just work great for me

Pretty good mug. It does keep the drink at a proper drinking temperature, doesnt die too fast.

As advertised keeps coffee at a specific temp that is flexible to what you want, easy to use. Downside is you cannot use regular silverware, it can scratch the coating. I use wooden stirrers and it works fine.

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.

This product does really keep the coffee hotter for a long time. It really works.

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.

This cup is incredible!! Any serious coffee drinker should get one. Your coffee stays hot for about an hour before it needs to be charged. If a person works, you can connect the plate to electricity from your desk, you can continually have HOT coffee all day.

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.

Bought this for my boyfriend and he loves it! He prefers it over an insulated mug, because it stays hotter and at just the right temp. It is a little pricy, but it's great for someone who works in tech and loves to have cool gadgets.

This mug is wonderful. Every cup of coffee stays at just the right temperature and the cup recharges quickly. Took one star off because it will not stay linked to the Ember app.

I like the concept of this mug. Overall it has worked well, 9/10 times getting it right that there is a beverage in my cup. My I main complaint is thst i feel tied to the charger. 80 minutes goes by faster than you’s think.

It’s a great product so far got it about three weeks ago and it definitely has done its job very well. I do think that it is a little bit pricey but thanks to Best Buy it was a deal of the day . I was very surprised at how great it works and the look is amazing.

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.
