Cleans up Real nice!
I have had this cooker/cup for about 10 years now and it has taken one hell of a beating. I have to say though that the cup has maintained it's shape over time and looks almost as good as new. It cleans up really nice. I like this cup because I can store cooking stuff in it with the mesh pouch it has a lid to keep things hot and it is incredibly lite. The sipper on the lid leaks by design so I recommend drinking with the lid off, but other than that I love this cup!
