Customer Ratings & Reviews

This cup is wonderful! It heats up perfectly, tells the temp of your drink then allows you to change the temp. If I had to say something bad, its only a 10oz. I see they now sell a 14 oz cup,I will be purchasing that one as well.

I have always loved hot coffee and continually putting it in the microwave was just annoying and wrong. I received this mug as a gift and will never drink from a regular mug again! I set it to my degree of warmth and it STAYS hot to the very last sip. And I can carry it wherever I go inside or outside. Absolute genius product! I would advise getting the 14 oz size to leave room for creamer and less spillage.

This really keeps your drinks warm. So far no issues with the mug or app. The deal price was definitely worth it.

I really like my new Ember Mug. It keeps my coffee the perfect temperature and the app is easy to use.

[Employee of bestbuy] Great gift for anyone that likes keeping their coffee and tea hot! Easy to use and set up :D

This was bought as a gift, and she said she loves it. It keeps her coffee warm for hours and is easy to clean. A little pricey though.

This product is great! Works as expected. I originally ordered the smaller size but returned it, highly suggest going with the 10z size. Sure does beat having to microwave you coffee in morning to keep it warm.

Pretty simple, does what it says. In the end it’s a very expensive cup. But if you drink a lot of hot tea or coffee, this cup will help your drink stay perfect.

Many hot beverages taste surprisingly different at even slightly different temperatures. This mug allows you to find your ideal temperature and it will keep it there for you. The iOS app needs work, but is functional if you can figure out the quirks. Overall I love this mug. If it becomes lost or stolen I will buy a new one immediately.

I bought this for my wife after she saw how much I enjoyed mine. I had bought mine a month earlier. These mugs are used several times a day and work perfectly. This mug did fail could not link to the app) and Ember replaced it for free even though it was 14 months old. The mugs are sturdy (coated stainless steel), I have dropped mine a few times, no issues to date. Very happy with the Ember mug.

Works great! I’ve found my perfect temp to be 130° and it maintains it that temp for as long as it’s on. I wish I had got the 12oz tho because it is a bit small. No trouble with the app so far personally

[Employee of bestbuy] Awesome cup works well and keeps drink hot and app is really easy to use.

The Ember app is user friendly and the smart mug maintains perfect temperature. The mug is easy to clean and has become an everyday item for me! This year, they will be perfect gifts!

I have wanted one for many years now and finally got one. Great for sippin on tea or coffee throughout the day!

I gufted this one of my guy friends for brithday. He loved it. Its easy to set use and a really cool product. Very helpful during work from home as you dont need to get up to warm your coffee.

Been wanting one and finally got one! Thanks to the hubby. Very useful. Really keeps liquid on the temperature you want it to be. Just pricey though for a mug.

This item makes me want to get rid off all my coffee mugs. It keeps it at a consistent temperature. The only downside is that it holds a small ounce size. Another great alternative would be a yeti mug.

I like having my coffee stay the same temperature to the last sip. I also purchased the lid for the cup.

I’ve wanted this mug for a long time. I’m one of those people who keeps traveling back to the microwave 2 or 3 times per cup of coffee. My experience so far with the ember mug is that it works, but it’s quirky. Most of the time it’s great. It’s wonderful to be able to pick up my cup of coffee 30 minutes after I’ve poured it, and have it be wonderfully hot. Problem is, this mug sometimes gets confused: The temperature will unexpectedly start dropping. Sometimes it recognizes it‘s mistake in a couple of minutes. Other times the app will say it’s 145° as it gets cooler and cooler. Sometimes that will eventually correct itself. Sometimes it won’t. So, with the mug I have, I have to use the reset button every 10 days or so for it to work. By the way, I had to replace the first ember mug I bought. It had the same behavior 50% of the time. Based on my experience, in the mixed reviews I read, there is a quality control issue. But I’m keeping the mug, after some struggle. I like the way it looks, the nice hot coffee most of the time. As others have said, a $100 mug shouldn’t act this way. But pressing a button every now and then is worth it to always have my coffee hot.

best christmas gift ever!! keeps my coffee hot when i am in a meeting!! love the color and the texture of the mug! and the blue tooth feature is amazing. now, my son and daughter want one too!!
