    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.

    These are the greatest mugs, I’ve had one for a few years and decided to get another color. I’m a slow coffee/tea drinker and I love how the Ember mugs keeps it my perfect temperature.

    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.

    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.

    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 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.

    Great mug. Works to keep coffee at 135 deg or your preference. Before I had to run to the microwave multiple times to keep my coffee hot. I like to slowly enjoy my coffee. Since Starbucks will not allow thermal mugs anymore, this replaces that and better. Enjoy your coffee 100%

    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.

    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.

    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.

    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

    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!

    Got this for my mother and she loves it. 2 out of 5 days she works for home and it does well with keeping her coffee warm while she is preoccupied with meetings and such. Thinking about biying one for myself
