Customer Ratings & Reviews

Cool idea. Battery does not last all day. It holds a good amount of coffee and the 10oz cup is too small.

I love this mug. I wasn't sure if I was splurging a bit on an unnecessary item, but I have fallen in love with this mug and use it daily. No more cold beverages becuase I was distracted or forgot about it for a few minutes.

Keeps my coffee hot and fresh. I love the ease of use as well!

Before my Ember mug, I used to have to reheat my coffee in the microwave -- sometimes more than once. No more! I love the comfort of warm drinkable coffee, and this allows me to set it just how I like it, and keep it that way while I'm working and sipping on it. I'm going to buy a second one for the office.

Works really well, the price and limited colors are the only thing that keep me from giving it 5 stars.

very nice product! easy to use and does the job well! Stays hot long after the product has started.

I wish I knew about this along time ago. This keeps my coffee warm at the temperature I set on my phone app. The secret benefit is that it warms up my coffee after putting cold milk in it. My only wish, besides a longer charge, is a larger 16 or 20 oz size. A 14 oz mug means 14 oz without the milk, syrups, etc.

Privileged. Did I need it? I didn’t think so until it was gifted to me. I use it daily. It works perfectly. Between working from home and taking care of two kids, my coffee would frequently get cold due to distractions. This mug is the answer. No more microwave trips for cold coffee.

I need to start by saying I love these mugs. I love having steaming hot coffee from beginning to end. That being said they have one major caveat. These things break apart inside and they don’t last long. The bottom flakes off. Always stirring the coffee in a different mug before putting it in here and rinsing right away doesn’t seem to help. They make a stainless steel tumbler that’s a thousand times better. We’ve switch to those and have had no issues.

Christmas present for wife and she loves it. Keeps coffee warm during entire workday. App is a little useless but fun to control. This does include a charging pad. Hand wash safe too. Definitely go with the larger oz size if the price is right, 10 oz is not enough these winter days in northern Wisconsin.

This just works. Coffee stays hot, no temperature fluctuations. It feels solid and has a nice weight. I invested a little more and bought a second charging coaster so I can easily move from room to room. Is this a ridiculous price for a coffee cup? Yes, it is. Is it worth it? Yes, it is

Perfect gadget for hot drinks! The standard temp without using app is 135deg which is okay temperature to keep your drinks warm but when using the app, max temp of 145deg is perfect! While on the dock it keeps the drink warm all day, when off the dock 70min? Perfect gadget for cold office! Highly recommended

Ember cup is super. Keeps my coffee warm all morning. Couldn't live without it.

Works great! Keeps my coffee or green tea at exactly the temperature that I prefer for the 60 to 90 minutes that I sometimes need to drink the full cup.

Bought as gift for wife and I’ve heard nothing but great things about this product. She loves the fact she can control the temp from the palm of her hand and don’t have to worry about other means to keep it warm.

No more sipping cold coffee or tea. This is the perfect size for those who use a Keurig to make their coffee, there is enough room left in the mug to add creamer if prefered.

Great mug keeps my coffee hot for hours!!!! The app is very intuitive as well!!

Finally, my husband can enjoy his coffee at the perfectly desired temperature! He’s been looking for the cup that keeps his coffee hot with little success until EMBER came into his life. A game changer indeed!

This is exactly what i needed. I drink slow and am constantly reheating my drinks

Best thing ever for a coffee drinker! I like the Ember mug so much that after buying this one, I bought another to keep at my desk at work. Prevents me from tossing out my coffee after it gets cold on me.
