Customer Ratings & Reviews

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.

The cup size is perfect. You can enjoy your hot coffee for a longer duration.

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.

Love how this mug keeps my coffee hot and is simply to set up

I really like this cup. Bought the 10 oz, perfect size. Sits on my end table. Great having a hot drink every night.

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.

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

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.

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

Amazing cup. It keeps my coffee hot for a long time!

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!

Girlfriend has been using it every day since I purchased this for her birthday. She never finished her coffee since it got cold during her morning routine. Now this keeps her coffee warm and she can stop wasting coffee. Easy to set up with the app. Have washed it multiple times by now and still no issues with it charging or working.

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.

Purchased this for my wife for Christmas. I know she’s going to love this gift!

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.

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!!

We love these mugs! Use them almost daily. They have different settings for different kinds of coffee drinks. The only knock is that the battery doesn’t last long. So charge it daily.

Very pricey but works great. Love having my coffee hot the entire time. I'm only deducting one star since it's not dishwasher-safe.

The Ember Smart Mug is so easy to use. So cool how it connects to your phone and you can control the temperate on your phone. Great for people who drink coffee slowly. Such a great gift idea!

Temerature control works very well and thw app is very easy to use.
