Pros: Collapsible, sturdy, aids baking
Cons: None so far
Bought from Kitchen Krafts online; comes from Linden of Sweden, same construction. No more trying to find a place to put a hot cookie sheet just offloaded, or where to stack a filled one ready for the oven. Used this making a bunch of cookies (two batches, one with four different variations) and it was soooo slick I wished I'd had one years ago.
