Customer Ratings & Reviews

This mug, while pricey, is a fantastic addition to your desk if you like to savor your coffee over time. It keeps it nice and hot and is super easy and intuitive to use.

So it works fine without the app, but the app is required to increase the temperature. The reason i returned it is because the battery only lasts an hour or so. Unless you're able to set it on the charger in between sips, it doesnt stay hot long enough in my opinion. Its probably ok at an office desk, but just isn’t practical for couch drinking. Plus, you obviously can't microwave it so we inevitably end up transferring the drink to a different cup when the nattery dies.

it does the job keep the coffee hot easy to set up

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.

Product works well. Disappointed in the size of the cup

Great product and a great Christmas gift or any Coffee or tea drinker. I wouldn't want to give this up now that I am used to hot coffee!

Excellent gift for coffee lovers, Bought this for my sister and she loves it

My wife bought me this mug for Christmas. I love it! My coffee constantly stays hot.

Love the mug as it keeps my coffee hot. As with the other reviews, the inner coating was flaking off my old mug but that was due to using a teaspoon in it which the instructions advised NOT to... Per the user's guide: "For best results, we recommend using a wooden or silicone spoon to stir as a metal spoon can damage the Ember's coating"). Don't let that discourage you from buying one, just don't use a metal spoon in it and it will last a long time.

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

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!

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

Great mug. It actually works and keeps the drink warm. You do need to charge it and also hand wash it.

Awesome coffee warmer mug. My wife love it because she takes to long to drink coffee

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.

Excellent gift for the coffee junkies in your life. They will love you

Awesome coffee cup!! I love it, I use it every single day.

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’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!!
