I have a small office with tall ceilings . . . needed to build shelving to go up. This shelving system was the way to do it in STYLE! I purchased 4 units and stacked them. They now hold my sculpture, art books and supplies. My young son built all of them for me . . . that tells you how easy they were to assemble! Pros: loved the white wood grain finish, great value, sturdy and very easy to assemble Cons: I have NO problems/cons with this product. I'm actually going to purchase 2 more for another room.
