Customer Ratings & Reviews

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.

Keeps everything warm. Does what it says it does. It’s good for one cup, so kind of sucks to refill if you drink a lot.

I got this for my wife for Christmas. She absolutely loves it! I’m not a big coffee drinker like her but tried hers out. You don’t realize how good a coffee is when it’s the perfect temperature though out the cup. I’ve since had to buy my own Ember mug. The wife says it was the best gift I had ever got her. Not sure how to take that seeing that it was just a coffee mug. But I know she is happy and me not so much. How am I ever gonna top this mug now?

It's a nice mug that may keep your coffee warm, this is for someone that needs it for additional hour (or 2 if you're pushing it) of good coffee (or tea, whatever you prefer). However, the battery isn't that last-longing. You have to charge it every usage. and that takes around 2-5 hours depending your habits and how often you charge your mug. If I have to be honest, I think you're better off with a double-insulated tumbler/mug that may keep your drink warm up to 5-8 hours a day.

Had a few issues getting setup with the app but once that was settled it works great and keeps coffee hot. Very expensive.

I was initially amazed, and embarrassed, that I spent this much for coffee mugs. But after using them daily we are hooked. At breakfast, even with delays while studying the newspaper or interrupted by a phone call, we can pick up our mugs and the coffee is still the correct temperature. Luxury? Sure. Cheaper to just take a glass mug to the microwave? Sure. But this is so much better! (By the way, 30 seconds in a microwave changes the flavor of coffee by extracting more chemicals from the "fines" which get through the filter)

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.

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

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

The coffee cup is a neat concept. Is it worth $129? Probably not but it does keep my coffee hot. Saying the battery lasts 80 minutes is very optimistic. Keeping my coffee at 140 degrees give me about 30 minutes before the red light comes on and it no longer warms my coffee and I have to put it back on the charger. Finally, you need to download the app to be able to adjust the temperature. I would prefer a "dumb" version where I could adjust the temperature on the cup itself.

The mug is a nice design and weighs about the same as a regular coffee mug. Coffee does stay hot but if you dont pick up the mug for 2 hours it will shut off. Overall its a great product.

Love the Ember! My coffee stays at my desired temperature the whole day! It is a little pricey but I think well worth it. I wish more colors were available besides black and white.

My boss loved the product.It keeps it warm for hours.

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

this feels so extra, but i love it. i have a toddler and I'm in grad school which means I often set my drink down and forget it. i love coming back to my ember and finding it hot.

Bought this for my dad for Christmas and he uses it for work and loves it. His coworkers are wanting to take it from him.

Bought this for a family member and he was super happy! Keeps coffee/drink very warm even after a while!

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.

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

Love it! Super convenien. Love the app. Works well.
