Title: Won't leak, but difficult to clean
Review: It is so nice to be able to throw this in my bag and not have to worry about it leaking and ruining anything! The problem, as reflected in other reviews is that it is very difficult to clean. I know others have had success cleaning their mugs, but I genuinely have not been able to get mine completely clean after a few months of use. It always still has the smell of dairy products (since I add milk to my coffee in the mornings), and the smell never leaves! I've tried brushes and everything but the smell remains, and some gunk seems like its stuck on there forever. I will purchase more of these mugs, just because I have to every few months, but I will continue buying them becuase they are such good quality and they are the only mugs I have ever found to never leak at all. Try one of your own!
