Customer Ratings & Reviews

I bought this item for my wife. She absolutely loves it. She loves the shape of the cup and the fact it's not heavy considering the technology. Her favorite function is that she can control the temperature from her phone app.

Bought for my wife. We dont need any more mugs for her. She loves it. Chargers great and easy to use. The coffee/tea she warms up is always hot. Always.

My husband loves this mug! Keeps his coffee and tea at the perfect temp!

Whoever invented the Ember mug is a genius! It has changed my coffee-drinking life, because I love my coffee hot! This product is not a luxury for me, it's a necessity!!! The only drawback is that it is not dishwasher-proof. You also can't put in a microwave, but you don't need to because it keeps your coffee so hot.

I got it for my wife and she opened the day of so I got her another one for her work and she said she used it and it almost burned her mouth so it dose keep drinks warm.

I like that it keeps the liquid warm for a long time at the temperature of my choosing. It unfortunately has connectivity issues and the app needs to be reloaded to connect.

This is must have if you are living in colder region… this will make sure the last sip off coffee taste like a first sip. Don’t worry about the price. It is a good investment.

As with many smart devices, I think the mug performs its function very well but the app needs a bit of work. I appreciate the features offered by the app (multiple temperature settings, etc.), but it consistently becomes disconnected from my phone when the app "forgets" the mug's configuration. When this happens I have to press and hold the bottom button to enter bluetooth pairing mode, which is made more frustrating when the mug has already been filled with coffee. Additionally, the app has been prompting me to complete a firmware update, but stalls out near the tail end of the install and never completes. Maybe if we could complete the firmware update then the disconnection bug would be resolved, but I guess we'll never know.

Love, not having to reheat my tea in the microwave with this mug. Makes for a great gift also. I also love the bold color

This mug is exactly what I needed for work. I love coffee, but when I get busy at work it always goes cold. This mug keeps my coffee at a perfect temperature all morning.

It does exactly what it says it does. No more wasted coffee

Is a really great quality mug and helps the drinks keep very warm and hot And does not allow them to get cold. functionality of the app is amazing also!

I love it so much I purchased a 2nd one a week later. Just so convenient not having to heat up my coffee with me being a slow sipper. All my other mugs are obsolete now.

Works just as great as advertised. Getting busy in the morning and still having hot coffee throughout the morning is really amazing. It’s not a big deal to make sure it’s charged every day, totally worth it.

I love the Ember mugs. It keeps your coffee hot and you can control the temperature from your phone. The only problem I've had with it is that it sometimes disconnects from Bluetooth ...and can take more than one step to reconnect. Other than that; it's a great mug!

Bought this as a gift for Christmas for a family member and they love it. Worth every penny. Having a desk job, they said they get busy and forget to drink their coffee quick enough to keep it warm and fresh. This allows them to enjoy that wonderful cup of coffee for longer

Great price and great service and quality super sale .

So I love that this cup keeps my coffee hot. It's an amazing cup. Downside is the app seldom works, upside you don't need the app to keep the coffee hot, unfortunately without the app you can't customize the temp. You will end up with the programmed temp.

Keeps coffee the perfect temp for hours! Can select the ideal temp you like and remains that way for hours. Also has a customizable led light in the event you have more than one mug.

I got this as a Christmas gift because I was going back and forth about do I really need it and the cost. I’m glad the hubby got it for me because I love it. I love that I can set my coffee to a certain temp and it stays that temp all day (yes all day because I have a toddler).
