Customer Ratings & Reviews

Love it that my coffe or tea doesn’t go cold. Its at the right temperature when i drink it. Especially when you have the AC and fan blowing. Love it.

I like to drink my coffee hot, and my 14 ounce temperature control mug keeps it perfect for me!

I purchased this coffee cup for my Wife as a gift, and she loves it. I bought it for her at a suggestion of another relative, as I would have thought it was too much money for it. But it wound up being a gift she uses daily, and she really likes it. Works well, she uses it for two cups a day, then it appears to need charging anyway.

What a great cup. I love how well it keeps your drink warm while you are busy.

Love this cup does keep my coffee hot all day. Im a coffee head it does everything i need and very durable and water proof im so happy with it ..i highly recommended it

Keeps coffee very warm , easy to use, different temps

Love my Ember mug! my coffee is always hot! Never again will i drink luke warm coffee!

default temperature is 135 degrees. With the app, I upped temperature to 140 degrees. coffee is more enjoyable at my desired temperature. I did not think 5 degrees would be noticeable, but it is.

It’s my second mug. I like them but battery time is limited to one cup.

Works great! This was a gift and they loved it! Fast shipping and delivery too!

Wife loves it keep it at a perfect temperature for most of the day

I actually bought this as a gift for my wife. Funny thing was she got me the same gift! Love this mug, it does a great job at keeping my coffee the perfect temp. I have 2 young kids so coffee is a must and hot coffee is even better. I have an iPhone X with no problems connecting the two.

I love my hot cup my coffee in regular cups cools off too fast I love hot coffee with Ember I can sip hot coffee for at least an hour Love it

I bought this for my boyfriend as a gift and he loves it. I’m going to gift him another one for Christmas since he said he loves this mug and thinks about getting one for his office.

I love this mug. I drink coffee slowly at my desk so it keeps it hot in between sips!

I don't like cold coffee! I spent the money to buy this cup, in the copper color, for me and my boyfriend. Even when a repair guy kept talking about whatever, my mind was on my coffee. When he finally left, my coffee was still hot. I was very pleased.

Actually works. I love how it keeps coffee hot indefinitely on the charger so if your sitting at the desk… it’s always hot. While not on the charger, it last a little over and hour but still hot and the about the 1.5 hour mark, it starts to cool down. It’s worth it so get it.

Wife loves it. But it's mainly for if you drink your coffee just black with sugar. We have learned that if you have cream or half/half, it will basically cook and you will have a skim on top. Great though. Would personally get the Ember2 so you could set your own temp. This holds true and keeps it hot for around 80min.

A must for coffee drinkers! I normally sip on my coffee while enjoying some kind of bread. My biggest annoyance was my coffee getting cold. This is the answer. Keeps my coffee for a warm 142 degrees. You wont regret it.

The price was great. I should have bought a cuo that holds more ounces. It works very well. It would be nice if the battery held out longer. That may be the reason it was on sale.
