    I can't stand a luke warm beverage. My ideal temp is piping hot. Happy to report this really does keep it more than warm & has customizable temps. Have already gifted two.

    Best in the market. By using the the device I am getting good savings on coffee. I can actually finish a cup at my work desk, without having to get up and get a refill on my cup.

    Works great! Was initially worried about some of the reviews mentioning difficulties using the app, but so far I’ve experienced no issues. Using the mug without the plate is still recommended though, as the coffee taste seems to alter very slightly after extensive use during a single sitting

    Does what it's supposed to. Easy to set up and use. Wish the coaster was a USB charger instead of a AC plug, which would make it easier for desks as if you want to use this for your day it's going to need to charge.

    This has been our biggest gift hit this year. People love it and use and rave about it so much that I’m putting the word out I want one for Father’s Day. Seems a little selfish to fork over the $100 bucks just for yourself but if I don’t get one as a gift I just might.

    I absolutely love this mug! It keeps my morning coffee hot when it’s freshly brewed and my dog decides it’s time to go for a walk. This mug has not failed me yet!

    Absolutely LOVE my Ember mug! No more reheating my morning coffee multiple times in the microwave. The mug keeps my coffee at the perfect temp for the full 90 mins off the warmer and continuously if left on the warmer.

    Love having hot coffee stay hot. Suggest buying 14oz cup, because 12 oz on my keurig fills to top, adjusting temp is inconvenient. Very expensive, waiting to see how long it lasts.

    I bought 2 of these over a years time. The first seems to working OK but it is white and terribly stained from coffee. I followed instructions for cleaning but it is still brown on the inside. The second was blue and I thought that would look better being a dark color. Unfortunately the blue one would not maintain temperature when half full so sent it back. I like the idea of keeping beverages hot but it is s high price to buy. Check out its performance while you can take it back.

    My daughter says this was a wonderful Christmas gift! She is a nursing student and right now a lot of instruction is online. She doesn't have to worry about cold coffee while in class and she can enjoy it from a regular mug rather than a travel mug!
