Customer Ratings & Reviews

Works excellently! Love the black. It made us want another one.

Bought this as a Christmas present for my wife. It has performed perfectly for her in about a dozen uses thus far. This size is definitely worth it over the 10oz option. It is expensive for a cup, yes, but a wonderful way to keep hot drinks at the perfect temperature. I was able to get it on sale at $100, and that's the price I would wait for again.

Highly recommend. Got it for my mom for Christmas, she uses it every day at work and said her drinks are hot consistently throughout the day!!!!

Wife makes the best use of it always having her warm coffee

A nice mug, but battery life can be an issue. For me, it heats my coffee for about an hour, but for anything more than that it'l run out of battery leaving you with a cold beverage. Not the end of the world, but as long as you work within this limitation it's a fun product. Need to be careful when washing, so that you don't get a lot of water into the underside (where the battery is housed).

Ember mugs are great if you enjoy hot coffee. I have a charger and extra heater so I can enjoy hot coffee for hours. Standard mugs lasts 1.5 hours.

Love the copper finish! It cleans well and seems to hold temperature really well.

Works great. A bit pricey but it was a gift. Keeps coffee hot!

I brought this for Christmas for my coworker/friend. She drinks tea throughout our whole shift. Our office area is constantly cool where she has to repeatedly rewarm her tea. I thought this would make the perfect gift. She uses it daily and love that her drink stays at the temp she like. Additional bonus is it works with an app on her phone.

Bought this for my friend who loves coffee, she fould it very easy to use and loves how you can adjust the temp on the app

Easy to set up and keeps my coffee hot! Very slick color

Keeps beverages warm. Easy app to use. Enjoyed it a lot.

I LOVE this mug. It is a wonderful product that provides and keeps my Americano hot. HOWEVER! As much as I LOVE this mug there is a huge flaw of this mug. The battery life. The purpose of this mug is to keep my coffee hot for a long period of time… but when the battery life of my mug is like an hour, it doesn’t last as long as it should. Basically you have to keep it on the charger otherwise it will die quickly and you just have a $100 mug. So in conclusion. AWESOME product that when it has battery, works amazing. It just doesn’t last long enough on a charge!

My wife has a home office set up with a mini fridge and coffee maker, and when she’s home working, she spends hours on video conferences, and when I happened to drop in on her, I noticed her coffee was often left sitting on her desk partially full. I know she likes hot coffee so I surprised her with this so her coffee will always be hot, and she is thrilled with the results, saying she never realized how much she missed having a hot cup of coffee during the day.

I've wanted to get my husband an Ember mug, but he thought it was too expensive. It IS a lot for a coffee mug, but he is really enjoying the fact that his coffee isn't continually getting cold before he can finish it. We've gifted four family members with Ember mugs over the past two years, and each one of them loves to use theirs.

Always keeps my cup to the perfect temp. App is easy to use and simple simple sjmlle. Highly recommend.0

This cup not only looks great but keeps my coffee hot for a long time. Then charge it back up on the magic saucer after washing. A bit pricey but I noticed lower prices for the season.

Ember works well. Maintains a consistent temperature. Only complaint would be regarding the length of time the cup is able to do so.

Very good product and works great, easy to use and worth the money for any one who would like to enjoy their drink for a longer time, or someone who has a lot of multitasking

If you love coffee, you need one of these! It is fantastic! By far the best gift I've ever had. It surprised me how much I love this new cup. Not only does my coffee not get cold as I move around the house, even when I'm using it at my desk keeping it on the charger, this cup let's me enjoy that cup even more. All the typical changes in temperature you don't even realize you've gotten used to in a cup of coffee are just gone. I promise you'll love it.
