I would recommend this product to anyone that is looking to consolidate products and free up shelf space.  I bought three sets and am amazed at the addtional space it gives me.

Pros: It doesn't take up too much room on the shelf and it's easy to see what you items you have on the racks.
Cons: A little flimsy putting the shelves together, but I used a pair of pliers to tighten those areas so they wouldn't separate and they're working fine.
