Customer Ratings & Reviews

The Ember smart mug is pretty good but not great. The 10 oz is not big enough but the 14 oz is too expensive. I would definitely buy the 14 oz version if money is not an issue. It’s too expensive for what you get. That said, I make a cup of coffee in a 15 ounce cup. When the 15 ounce cup starts getting cool, I dump it in the 10 ounce Ember mug. Not very convenient. The battery is really bad. Believe the other reviewers when they say this. You must keep it on the charging station if you do not want this to die. If they can make a 14 oz cup with a long lasting battery at a reasonable price, this could be an awesome mug. I’m giving this 4 stars instead of 3 because the app is awesome. Pairing is easy. It will alert you when your coffee is at the correct temperature and if you can keep it on the charging base, you will not have issues. The app has presets for tea, water, coffee, etc. Overall the mug is pretty good, but consider buying the 14 oz version if the price decreases.

I really like the way I can control the temperature of the liquid in this mug. Best part is that I can place this mug down anywhere and it will keep my beverage at the exact temperature. I am also notified when my beverage reaches the desired temperature.

This was a birthday gift for my wife. She isn’t much into tech items, but she loves her morning coffee. She absolutely loves this coffee mug and hasn’t used anything else since getting it. It seems to be high quality and easy to use. We linked it to her phone and she enjoys getting texts from the mug. Attached is a picture of a text she just got saying the coffee is ready. We originally got her the 10oz mug but it didn’t leave enough room for her massive amount of creamer she likes to use so we upgraded to the 14oz one which is perfect. She likes that this mug helps keep the creamer from cooling down the coffee. We highly recommend this mug but it is a little pricey.

So far it's amazing but an 8 oz keurig dispensed with cream and sugar does not fit this very well I would go with the bigger size if you like cream in your coffee ! But it has definitely kept it cozy!

The Ember Mug is a game-changer for anyone who hates lukewarm coffee or tea. It keeps your drink at your perfect temperature for hours, which is fantastic for slow mornings or long work sessions. The app is easy to use, and the charging coaster is convenient. It's a splurge, but if you value consistently hot beverages, it's worth it.

I hate when my coffee goes lukewarm, so this was the perfect product to enjoy my morning coffee at exactly the right temperature. Super easy to use and clean. And looks great on my desk!

A smart mug is one of those things that sounds ridiculous at first but you'll quickly find out how awesome it is. I have a lot of distractions at work so it's helpful to have a mug that maintains the perfect temperature while I'm in a meeting.

I’m in love with my Ember cup! Instead of leaving my desk to warm up my tea/coffee, the Ember keeps it nice and toasty for me.

The reason I gave it a four. Was because it’s a little pricey. It was a Christmas gift for my son-in-law. He takes it to work. He owns a gym. This keeps his coffee warm while he’s training.

The technology is phenomenal it does what it claims however the cup is slightly too small at filling completely at the 7.76oz nespresso pod I use. I am unable to add creamer without fear of spilling.

Going strong almost 4 years now. Still works like new. The charger base has been replaced twice though. Best coffee investment in my lifetime.

I love this cup. Such a thoughtful gift from my daughter. I use it everyday.

Works great and keeps drinks warm! Definitely recommend!

Awesome product. Having consistently hot coffee is way undervalued.

This thing is wonderful for morning coffees - if you have an outlet near a side table the dock is great to have handy and not an eyesore. Only thing I'd say is opt for the 14oz if you're a heavy coffee drinker.

Mug keeps coffee hot as advertised, easy to pair with phone to customize heat settings, comfortable to hold and drink from, I’m purchasing another one for my mother. Highly recommend.

The charge doesn’t last very long. I like It, for about 1 1/2 hours. For $100+, I’d expect 3 hours or longer off the charger.

This mug itself has been fantastic. A self-heating coffee cup, the future is here! The app and bluetooth connection can be a bit fiddly but when it works its a dream. After having this mug for under a year and a half having exclusively hand washed it, the inside of the mug is flaking off. Just a few months out of warranty and it's unusable in this state unless I would want to inevitably drink whatever material it's coated with. I've reached out to their support team and am waiting to hear back but in any case I would encourage researching the coating flaking issue online if you're considering anything from this line.

What a huge disappointment!! I like my coffee hot so I’ve been very careful with making sure the base is charged. What I didn’t plan for is the interior paint/coating to be chipping off ~ I’ve never put it in a dishwasher or used anything metal for stirring my coffee so I’m perplexed as to why this is happening. Tried customer service at Ember multiple times..no connection ~ no response!! For the cost of this mug there should be better customer service! What a BIG DISAPPOINTMENT!!

I received this mug as a gift, and it's perfect. I paired it with the app, which can be a little glitchy, but not a complete waste. You can control how hot you want you coffee, up to 145 degrees. Also, if you share your mug, or have the same color, you can customize the LED color to identify who the cups belongs to. You cannot microwave your cup, but honestly, I have poured in cold creamer and waited for my coffee to get hot just to experiment. It's neat. And if you pair the mug with the app, you can choose which temperature to maintain your coffee. I charge the cup after using it, and will simply take the cup with me to my home office for a few hours. Battery life away from the base depends on the maintained temperature. Overall, I love this mug, because it's not your typical mug plate where you have to keep the mug on the base. You can also wash the mug, but not keep it submerged in water, I recommended immediately washing it, or if you don't have time, fill with regular water to soak, turn off the base, and clean it later. Again, just don't submerge it or it will ruin your cup. All this is in the nifty packaging it comes with! I would recommend as a gift, buying it for yourself or to impress your guests.
