Customer Ratings & Reviews

I had initially purchased the black version for daily use at my office. I was hesitant at first as I thought it would be gimmicky, but turns out I love the mug so much I ended up buying one for my girlfriend. We both love our ember mug and find ourselves making excuses just to have another cup so we can use it more!

While the volume it holds is on the small side, the cup works great for keeping my coffee hot while in meetings - and some can go long! Would buy again, but a larger size.

my husband and I like to drink our coffee leisurely in the morning. Often the coffee would become lukewarm. This never happens with our coffee now. It stays perfectly hot, (we set our desired temperature) until the last drop is gone. We feel perfectly spoiled with our Ember cups!

Not a fan of the 10oz size, but the two pack is a nice deal. The 14oz is more my preference, but other than that these cups are amazing and would absolutely recommend to everyone!!!

Very cool mug. If you find you have to microwave your coffee a lot because it gets too cold this item is perfect. It does have some trouble reading sometimes but it works great 99% of the time

I really like this product. When I'm watching TV or a movie playing video games and forget about my drink it can be reheated right there or I can have it on the coaster and set to keep its temperature for the better part of the day so I can drink one cup the whole day.

Works perfectly and keeps coffee at perfect temp for several hours, but will burn it if unattended or not turned off. Only regret I have is not purchasing the larger 10oz mug.

Can’t start your day without coffee? Do you drink more than 2 cups a day? This is what i needed. And all hot coffee drinkers will love. Wish it was cheaper.

I bought this for my co-worker who constantly has to reheat her coffee. She was excited to receive it, but will not use it during the summer. It seems to be a great cup!

Overall a pretty great mug. Makes for a great gift for any coffee lover. Only downside is the battery life when the mug is removed from the coaster.

I wanted to like these but the battery didn't last much longer than an hour. My spouse can take a long time to finish a cup of coffee and I was hopeful that this would keep her cup warm, but alas, it only lasted about an hour. With a long charge time, it didn't meet our needs. If you can somehow keep the charger at your desk and have it charging all of the time, then this might be for you. I ended up returning them.

I was hesitant at first as I assumed this mug would be gimmicky, but reviews were positive so took a chance. Turns out I love this mug and couldn’t imagine my day to day cup of coffee without it. I even find myself making excuses to have more coffee just so I can use it.

I bought this for my mom for her birthday and she tells me every morning how much she loves it. At first she thought it was a bit small but after consideration she thought it was perfect. She uses it every morning and I recommend it to everyone. What a great gift!

My wife is always reheating her coffee. So I bought this for her and she absolutely loves it. She says that it keeps her coffee more than hot enough. Only down side is she can’t put it in the dishwasher, but she doesn’t mind hand washing it.

Great concept and very nice presentation. However the battery only lasts one cup and needs recharging again before cup #2.

It is truly wonderful to have your coffee remain at a 145 degree temperature for an hour or more! This cup informs you when your desired temperature has been reached. You can easily adjust your desired temp up to 145 degrees!

I needed a cup that would keep my coffee hot at work while waiting on customers. I work retail and when I had to help someone and then return to my drink it was always cold. This does the trick and keeps it hot. I loved this so much I purchased one for my daughter.

My wife really loves this mug, bought it as soon it was on display, since day one has kept the coffee and desirable temperature and is controlled by app where you can personalize to your own preferences. Still looking like new!

You get what they say a high quality product presented beautifly. It could even save me money, less waste, but the big reward is, hot coffee. and their support is above good. Yes $$$ but what the h? Next their Travel Mug when i get the loose change.

Great so far, have been using for a month with no issues. Love having perfect temperature tea and coffee. Wish there was a wireless coaster (something with a bigger battery to recharge around the house without plugging it in).
