Only improvement I could use is a cover. I am still looking for one that fits securely. Ember designers have my comments. Not only would it keep airborne particles out of the coffee it would increase the battery heating cycle time by almost an hour. This is due to the reduced surface area exposed to the ambient temperature. Syncs with Android and has worked flawlessly over the month I have been using the Mug2. I thought a second charger might be nice, but not necessary unless I was to walk around with an cold mug of coffee. That has not happened yet. The Mug2 is heavier than other vacuum mugs due to its internal electronics and battery. The 14oz is measured to the very top of the rim. 10oz pod coffee maker setting leaves room for milk and the ability to carry a full cup of coffee around. A 12oz setting is fine if you do not use milk in your coffee. I do drink tea, but have not tried to brew tea in the Mug2. But the settings are in the app. The Mug2 is one very impressive addition to my many "toys", not to say the mug is a toy, it is no toy.Read full review

The mug is working well so far. Coffee doesn't get as hot as my previous mug from a different brand. The app for the mug on the other hand is trash. It constantly disconnects from the mug. When I exit the app and then open it later, I have to re-pair the mug. It's like the app has Alzheimer's. The app also crashes every time I try to do an update. It gets to 2% and then hangs. So if your main reason for buying this is the ability to control the mug with the app, I'd stay away from this product.

One flaw for me: Doesn't keep the temperature setting for my second cup.Otherwise, I am very satisfied, I bought 2two for my kids (48) years old and they bought one for a friend.

Awesome product, keep my beverage hot and to the exact temperature I prefer. During work, I used to drink half of my coffee before going cold; most of the time I never finished my drink. Now, whenever I get busy, I'll go for 20 minutes to an hour before taking another sip of my coffee, it tastes fresh and feels exactly how I like the desired temperature. Definitely, will buy for family and friends as gifts!

I owned a white Ember cup previously, and it was stained from coffee. The black color hides the coffee stains, and it is much more attractive. I love that the Ember cup keeps my coffee at the right drinking temperature, until I am finished.
