Negative Positive
Title: Nice idea, bad design implementation.
Review: It looks nice and it does prevent some spilling, but it has a couple of flaws. If you take a sip and then release the auto-seal button before you level it upright, the leftover coffee on the lid could splash as your lips smacked off the lid. The inside of the lid is also poorly designed with a lot of hard to reach corners and openings making it very hard to clean properly. I figure I would throw this mug away after 2-3 months to avoid drinking my fresh coffee with too much unwanted mineral/soap/old coffee deposits.
