I bought this and I wasn't sure how I would like it, but I love it! Perfect for making me scones and pie crusts (they have to be rolled out to a specific amount of inches in diameter)  Also I like that it gently sticks to the counter surface so it's not moving but not hard to remove from the counter either.  It's easy to clean, just soap and water and the hand measurement conversions aren't a bad touch! I love it, used it 3 times this week (Cinnamon Chip scones, pie crust for a Red Pepper Goat Cheese Tart, and blueberry scones, YUM!)

Pros: Easy to clean, good amount of measurement options, conversions of all types, and stays in place when using it.
Cons: Wish they had the 7" diameter but it was easy to estimate.
