Upon unpacking and trying it out, I had to laugh out loud "great design." This thing is made of high quality materials, rather heavy, folds flat for storage and... adjusts to the amount of napkins stored within. It can't get any simpler and smarter than that. Works perfectly for all kinds of napkins and, for me, has solved a lingering problem of perfect napkin-holding. Highly recommended!  

Pros: Smart design, easy flat storage, heavy and high quality materials, clever functionality
Cons: None at all
