Title: Impossible to clean... gross
Review: I got one of these mugs as a present and I loved it at first, but the lids have crevices and moving parts that are darn near impossible to clean. If you drink anything but water, the fluids are eventually going to build up in the lid and start growing mold. Didn't realize it until i tapped the lid on the counter top one day and noticed all the gunk that was coming out. It's a great seal for keeping my coffee from spilling out, so I tried using this mug for over a year, but I finally gave up on it this afternoon and decided to throw it out b/c it's too much work to try to clean this thing out.
