This is now my favorite coffee mug!!! I love ninja products. My whole kitchen is basically ninja. Anyways the coffee mug...its works so well from the first drink to the last. No burnt mouth and maintains the temp very well! I have not run into a time where it was cold to drink. I definitely recommend purchasing this!

Edited to add: It doesn't keep drinks as hot as I'd like. My Yeti does a better job. I do like that it's easy to keep clean. I wish the base were a little narrower to fit in my car cup holder. Still glad I bought it. I was intrigued by the premise of this mug. Like competitors, it isn't cheap. Normally I alternate between a Yeti and a Stanley. I expect my mug to fit in my car cup holder and keep my drink hot for at least an hour. This mug is larger and feels sturdier and heavier than my usual go-tos. I like the color choices and the bottom cover. The top is very ergonomic to the mouth, which is nice. I feel like the mouth shape is one of those things I will now expect on other mugs. The one disappointment is that opening and closing it makes a rather loud snapping noise. Thus, while I'd planned to take it to work and travel with it, I'll probably keep it at home since the noise could be rude in a work setting. It is easy to clean -- fewer parts and fewer places that can trap disgusting gunk. It keeps my drink hot, but I don't think that aspect is superior to other brands. Overall, I'm very pleased.

Purchased this to replace another brand. I’ve had it for a couple months and use daily. One of the main functions I liked the best is that the lid can easily be cleaned. I use cream in my coffee and the last mug had areas that were not easy to clean. I also like that it brings scalding hot coffee down a few degrees so you don’t burn your mouth. It does keep my coffee drinkable temp for at least 4 hours. Even in very cold Colorado winter temperatures. Mine does not leak and fits my vehicles cup holders. Unfortunately, the 16oz is too tall to fit under my Nepresso machine. I also wish it came in red. Otherwise, great coffee mug. Highly recommend.
