My wife loves the mug. She uses it at work and her coffee or tea stays hot for hours

Great value, nice color and keeps beverages hot at a temperature selected. I wish they would come on a larger sizes

Looked at this cup for a while before actually purchasing. Thought it may be another gadget I picked up or novelty would wear off. It was on the deal of the day and I took the plunge. Now, I'm about to buy the 14oz. I use it everyday and love it. I can walk around with a cup of coffee and it truly stays hot. If you're used to using the larger setting on the keurig or like a larger cup of coffee, I would suggest buying the larger size.

I bought this for my mom who loves coffee. She really likes that it keeps the temperature you set it at for up to 90 minutes on one charge off of the base. You can control the temp you want your beverage to be. Also if there are more than one in a home same color you can customize your light on cup so you know which one is yours, overall a really great product.

Very simple to use and is easy to clean! It also can warms up drinks pretty quickly

perfect design, easy to use, introduce to friends, everyone is happy! it's also the best Christmas gift!

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.

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.

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

I already have a mug and a travel mug. These are the best cups i have found for traveling, at my desk or just lazy afternoons. I even bought a few for gifts!

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

This cup does exactly what I needed to! it keeps my coffee warm so when I end up in those extended conversations, I don’t have to worry about coming to a cold cuppa coffee. I love the cup, and will likely buy more to give to my friends.

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

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.

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.

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.

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.

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

This was a gift for daughter. She said it works great. Keeps her drinks hot at home.

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!
