Customer Ratings & Reviews

I bought this for my husband bc he works from home and always leaving his coffees to sit and get cold. He didn’t ask for it, and kind of gave me a weird look when I gave it to him, but now he’s a total convert. He’s in love. He uses it everyday, all day, and tells everyone about how great it is. The only thing is that he fills it to the brim when he pours out of the keurig. I probably should have gotten the next size up.

Great product. Don’t need anymore disposable cups, even better I don’t need to rush to drink my coffee! I can relax and enjoy my warm cup of coffee every sip of the way!

If you're a serious coffee or tea drinker and you like your drink to be consistent on temperature, even if you have to walk away from it for a period of time, you must have this mug! It works so well to keep your drink at a constant temperature and preventing it from getting cold and gross. My wife loves her multiple cups of morning coffee and she gets excited every morning to use her Ember.

Easy to use. Value just fair. Quality is very good!

Love having hot coffee all morning long easy to use, perfect for all hot beverages. Perfect for my at home office.

Gone are the days when I go to the microwave every 30 minutes to reheat my coffee. The only negative thing about this mug is that it doesn't hold charge enough. I find myself leaving it on the desk, instead of the coaster, and sooner than later get a notification about the battery running out.

This was Purchased for my Wife for Mothers Day. She Loved it. Very Easy to Set Up. AND IT ACTUALLY WORKED

Absolutely the perfect mug the most avid coffee enjoyers and the occasional drinkers! It keeps my coffee warm all morning long at the temperature it came out of the pot. Cannot recommend enough

I enjoy a cup of coffee in the morning while reading the paper, etc. In the past I would throw out a lot of coffee because it got too cold and I didn’t like the way the coffee tasted after reheating. My wife says I’m a coffee snob. The ember let’s the coffee cool to a temperature I selected and keeps it there. Perfect coffee to the last drop. Expensive, yes, but we’ll worth it for someone who enjoys their coffee.

I bought this mug for my employees as a Christmas gift and they love them! It’s so handy for people who want to have warm coffee all day. I need to buy one for myself!

Gave this as a gift after having bought one for myself. The recipient loved it.

This mug is a game changer. I typically drink my morning coffee or tea slowly (over an hour or two) and hate that it's cold before I'm half way done. With this mug, it's the perfect temp the whole time. The charge typically lasts long enough for a morning. If it is running low and I want to keep it going, I put it on the charger while I'm still using it. The 10oz is typically enough for me but is on the line of not being big enough. I would purchase the larger size in the future.

It’s very nice. Keeps coffee at the set temperature. The cup needs to be larger

I bought this as a gift for my mom on mother's day. She's a big coffee drinker and I thought she would like to have something that keeps her coffee warm. The included saucer is a plugged in charger that will charge the cup each time you set it down. She likes it a lot.

My wife loves this mug. She likes to relax and read while she sips coffee and this keeps her coffee or tea warm for a good hour or so she can enjoy reading and a hot drink. Your ideal temp is easy to set via the app.

As an office worker, this product is a must. Keeps my coffee warm all day!

We bought this as a means to end microwaving coffee time and time again. But upon receiving this gadget we realized that this is a necessity in our household so much so that I want to buy another. We love everything about this mug my wife especially loves it because she can reheat her coffee her tea and see the temperature on her phone.

For me this came down to a personal choice. I appreciate my coffee being kept warm and not needing to run to the oven when it cools down. The app isn't annoying for me and enjoy I can modify the temp down to the single degree! No issues yet washing or using. Got it during the holiday season so price was much less of a barrier!

This mug is well built and it keeps drinks very warm.

In terms of quality I have no issues with it at all. If you only drink one cup a day and have a lot of room on your counter to charge it every day and you want a mug that will keep your coffee hot this mug is for you
