My garage/workshop desperately needed this storage rack. I currently have many heavy boxes filled with license plates on two of the shelves and paint cans on the other shelves. The rack doesn't shake or budge at all. I feel confident that the shelves will continue to hold my heavy items without a problem. The rack works so well that I will be purchasing a second and possible third for more storage in my garage. It's a great height and looks strong and sturdy and the color fits well in the garage. I have no "cons" as of now. I had a storage need and this item exceeded my expectations.
