Directions were horrible. Basically no directions at all and no specific directions about putting the supports together. Product is okay but it works for us. This would not be heavy duty enough for super-heavy items. Also the chipboard shelves are cheap.
I am so glad that my son recommended me purchasing them. They allow my garage to be so neat and I can store basically anything on them I have even stored 2 tires on top and a Mercedes Rim. Great buy.
