    Nice product. Keeps coffee hot as advertised. I thought the battery would last longer though. It only lasts an hour, maybe a bit longer. Overall I am happy with the product.

    This was my second mug and I love having it keep my tea at my perfect temperature. I got the second one because I use it so constantly that it allows me to use one overnight while my other one is charging and ready for travel in the morning.

    Great cup! Everything works well and is easy to use. My only complaint ( and it’s mine, not the manufacturer) is that the cup is too small! Should have bought the bigger one!!!

    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?

    So far so good. Wish the maximum temperature could be set to 155 as 145 is just about warm for my taste. I was debating between 10 and 14 oz due to additional cost. But ended up going for 14 oz and glad that I did. 10 oz would have been too small and require frequent refill. You might as well heat in the microwave on refill visit. 14 oz also carries perfect amount of heft and feel. You know you are holding something good with or without your tea or cofee. That said, be careful while washing (handwash only) as the contact points (the two circular rings) with charging coaster are visible and exposed.

    My husband and I each received an Ember mug as a gift. We weren't sure if they really worked. They do! We've been using them for over 2 years and love them! I'm a coffee drinker, but also drink tea. I'm able to set the temp that I prefer for whatever I'm drinking. We use them every day and recommend them to anyone who enjoys their coffee or tea the same temp with every drink.

    Keeps coffee at the correct temperature. Battery life is a bit shorter than desired, but if on the charger it works for multiple cups throughout the day. Good investment.

    Expensive, but worth it if money isn't an issue

    It's a completely unnecessary product and far more expensive than it's worth, but still, I use it every day and love it. It takes me a while to get through my daily hot beverage and either poured out the last bit or just took a big swig to finish off the cold remains...but with this my drink stays the exact temperature I want down to the last drop. The 14oz is a little inconsistent in the temperature sometimes...the bottom of the cup can have the liquid a higher temperature than the top depending on how long your drink has been sitting. It's a big mug and exposure at the top since it isn't sealed seems right.

    Ember works well. Maintains a consistent temperature. Only complaint would be regarding the length of time the cup is able to do so.

    Bought this as a gift for a family member for Christmas, and the recipient really likes it for their tea. It is very well insulated on the outside so you don't burn your hands holding the mug like some others. Only complaint is that the battery life isn't the longest, but I saw that the lid you can buy may extend it to a certain extent, so that may be worth a try.

    Great for Keeping Beverages Hot! This is very convenient for anyone who likes to keep their beverages hot for longer. It does the job well and is a great addition for those who enjoy warm drinks throughout the day.

    My wife has a home office set up with a mini fridge and coffee maker, and when she’s home working, she spends hours on video conferences, and when I happened to drop in on her, I noticed her coffee was often left sitting on her desk partially full. I know she likes hot coffee so I surprised her with this so her coffee will always be hot, and she is thrilled with the results, saying she never realized how much she missed having a hot cup of coffee during the day.

    I love that it keeps the coffee at the perfect temperature for me. The battery won’t last more than 50 minutes off the charger, but I usually drink it with the charger nearby so that’s fine. My only ding is that the charging pins stick after a while and it struggles to maintain a connection to properly charge
