    I have to put this cup down as one of the best gadgets that I have ever purchased! It's great! It does exactly what it says it will do. I can walk around the house for hours with it and it keeps my coffee, tea, etc hot for the entire time.

    Purchased with the expectation that the mug would keep warm drinks... well warm. It does just that. App works flawlessly and the mug does exactly what it's designed to do. A little pricey, but the actual product quality reflects that price. This thing has some weight to it!

    Works well just as intended. The reason I'm only giving it 4 stars instead of 5 stars is because it's fairly small in size compared to how much I drink in one sitting so it would be a lot more useful to me in a larger size.

    I bought the Ember Smart Mug for my wife for her birthday. The ember smart mug keeps her tea at the perfect temperature for about two hours when not sitting on its base. If it sits on the base it keeps it at the right temperature indefinitely. She's enjoying the mug.

    Bought this for my husband to keep in his home office, he loves that it keeps his coffee hot and that he can set desired temperature. Washing is a bit tedious as I don’t like to get the base of mug wet, but otherwise awesome purchase.
