    Great product and love the temp control! Only wish it was a little bit bigger. 20oz maybe? Otherwise great product!

    I purchase this for my coffee-drinking girlfriend. She is a slow coffee drinker and has to reheat her coffee in the microwave several times each morning. I thought this would be the perfect gift, and she loved it. It works exactly as advertised. The cup stays warm and there is no more use of the microwave for this task.

    I bought this mug for my boyfriend for Christmas and I use it just as much as he does. It’s perfect for the colder months. Definitely keeps my beverages warm and get this, if my coffee has been in the French press for longer it reheats the coffee as well. Definitely buy it!

    This cup not only looks great but keeps my coffee hot for a long time. Then charge it back up on the magic saucer after washing. A bit pricey but I noticed lower prices for the season.

    The mug does an excellent job at keeping the coffee warm. The app is a bit finicky and needs to be updated.

    Worth every penny! Would recommend for all my fellow neurodivergents out there that have taken a sip of coffee only to realise it’s been cold for 20mins whilst you’ve been doomscrolling on the socials. Buying another one for the wife!

    I've always enjoyed coffee, but I don't like it too hot, and I don't like it too cold. First world problems, I know. However, my Ember cup has changed my world. I make a cup, wait until it reaches my set temperature (128), and then start sipping it. Amazingly, my coffee remains at 128 degrees from that first sip until the last one. If Maxwell House had not already used the phrase, "good to the last drop", then I would apply it to Ember, which would be more true. This thing is worth it!

    Cool idea. Battery does not last all day. It holds a good amount of coffee and the 10oz cup is too small.
