It does what a good coffee mug is supposed to do - keeps hot stuff hot. However… I find the mouth piece/lid a little too small and consequently, coffee will occasional flow around my bottom lip and onto my shirt if I am not paying attention to it. Feels like I am drinking from a child’s cup with a lid on it. Also, I have been “bitten” by the lid if I use the palm of my hand or more than two fingers to close the lid. Would I recommend this item to close friends? Probably not due to design issues with the lid.
I already love anything Stanley but this one hit homerun for me. Quality is already no need to be explained but the color and elegant design! I love it.
I bought one of the 16oz AeroLights at a store a couple of years ago and it was the best hot coffee container I have ever had other than another Stanley product. It was portable, did not spill, fit in my cars cup holder and kept my coffee hot for at least 3 hours. Liked so much I bought the 20oz.
