Customer Ratings & Reviews

I purchased this mug for my techy bf's birthday. He LOVED it! I tried it later and loved it too. Long story short, we have 4 of these mugs now for home and our offices. Just make sure you hand wash it, and put it back on charger once it's completely dry. Also, don't use a metal spoon. We got silicon spoons to protect the mug.

We owned the first Ember and upgraded to a bigger one (Ember 2). My wife uses this thing almost all day. Coffee that remains delicious all morning and evening Tea that remains hot. Defintely worth every penny if taste and quality of your drink are important to you. You don't have to rush to finish your drink in fear that it would go cold. A person who cannot control when their job or kids will need something should definitely consider getting one. Even after leaving for an hour or more, you come back to a delicious and hot drink.

I have owned 5 of these mugs and they are great for about the first year. A couple of them didnt last that long and I had to submit a warranty claim. Ember was good about the replacements but they have also deteriorated quickly. We do use them daily.

Great looking coffee mug however aside from looks, the functionality can be a bit better. Heads up for future purchases if for whatever reason you reset the mug by pressing the bottom button intentionally or unintentionally for more than 5 secs and see the colors flash.. that does mean it's reset the mug settings and you'll also need to manually reset your Bluetooth pairing from your mobile device (meaning forgot the device and then re-add as new device) in order for it be reconnected after reset and fluid detection to work. For the longest time I could not figure out how a filled coffee mug would read as empty. With that the battery life does struggle to lasr for my two hours of heated content sitting out on desk. So be prepared to have charger ready for charging if intended to keep intended temp for longer than that.

I had never thought that a few degrees in the temperature would actually make my coffee or tea taste better. It does. You know when you make coffee, pour it into your mug and for a few minutes it is too hot, then for 2 to 3 minutes it is perfect and then too cold? Well, what if you could keep it always at that magic temperature that lasted 2 or 3 minutes? That is what Ember does for you. There are additional perks, it lets you know once the temperature is perfect, it can warm its contents even from ambient temperature if you want to and the materials are quite comfortable to interact with, they don’t change the taste of the beverage. We bought both the 14 and 10oz versions. The only difference aside from the color is that the 10oz heats up a bit faster, but that is it. Overall, if you’re constantly drinking something or going to meetings, this is the best mug to have.

Can't live without it for my morning joe. Keeps it hot while I sip and read the news.

This was a gift and she loved it. The cup keep the coffee warm to her temp. The phone app. is really simple to use. Great buy

This cup is amazing. Its putside is cool to the touch, but when coffee is poured, remains at a hot temperature to your liking. Recommend the 14oz cup over the 10oz cup

The mug itself does a good job at keeping the drinks warm, the enamel paint is peeling off after around 6 months. Not sure if its worthwhile investing in another mug to see if this happens or not.

Got for my wife she keeps it in her office and loves it. Says her coffee is always the perfect temperature

I purchased the mug Feb 2022 for a Valentine’s Day present for my wife. She uses it every morning for her coffee and swears it has been the best thing ever! The only problem we have had with it is charging. You have to make sure it sits perfectly and wait for the flashing red to flash a couple of times. Besides that it still works just as well as the day we got it. If you take care of it and make sure it’s dry before setting on charger you will enjoy it!!!!

Haven't used it much yet, but its been great for teas. I tend to take my time drinking my tea and it's usually cold by the end. This fixed that issue.

Great mug. Love that it’s not hot on the outside but the drink is hot inside. It works great. I wish they made it a little bit bigger like 16 oz and somehow make it last a bit longer. But great concept and works very well. Coffee is hot till the last drop!

Keeps your drink hot. I like that you're able to choose your perfect temperature. Given that I am a slow drinker, I wished the battery lasted a little longer. Overall happy with my purchase.

I have bought two of these now and they work well. If you give to someone that uses the microwave to heat their coffee hide or unplug it. They will quickly burn the circuits and no longer work.

Great cup to keep beverages hot and at your choice temperature. Lasts for over 4 hours off the charger. Sometimes it’s difficult to connect to your blue tooth. Other than that great coffee mug - love it! Would recommend

Love the cup, not the battery life. Unless I keep on charging plate doesn’t last through couple cups on Sunday mornings cooking breakfast and reading the paper.

[Employee of bestbuy] Sure this mug is costly but it’s worth it. I love how it keeps my coffee warm and saves me trips to the microwave to reheat my cup of joe. One important thing to note is that you cannot use a metal spoon to stir your coffee. This will damage the coating of the cup. A recommendation to the manufacturer is to clearly point this out in the instruction packet, and or put a disclaimer in the specifications to avoid future issues. Based on other reviews that point out the damage shows this was often missed.

These mugs are great and do what they say they'll do. App is easy to use. Just make sure you don't leave it partially full, it'll keep working and the coffee with cook to the surface. Fortunately it's fairly easy to clean, but with the automated on/off, even if you turn it off, it seems to sense the liquid in there and turn itself back on. Just dump it out every time and you're good.

Love having my coffee always the temp I want! I never have to top off the cup to keep it warm!
