I really like the sleek design of this mug. It is so easy to clean unlike other mugs that have fancy tops. This top is great. Yes, you have to remove it to drink out of but it really isn't a problem. The minimalist design and ease to clean far outweigh the inconvenience of needing to remove the top. Plus, as far as I can tell it is completely leakproof.
I didn't think I would use my thermos all day, everyday. Not only for my green tea addiction, but for a simple water vessel as well. The splash guard is brilliant. I never liked thermos' for the awkward sipping lid that most of them offer. The liquid comes out at a slower rate so you aren't risking burning your mouth. Nothing but smooth sipping here.
The Carter Mug is a quality piece. It keeps my coffee warm and the elegant design gets noticed and commented on often. This is my 2nd one. The first was lost and I didn’t hesitate to order another.
