This is a very well engineered and thought out product. I purchased a laundry room shelf and cabinet system from them as a "test" before I committed to a full closet system. The product arrived in 5 cartons, well protected with nothing broken or damaged. Instructions were excellent and the quality is very good. The fasteners are well designed and work perfectly. It's worth your time to read the instructions first! Also, You can do a rough design and submit it to them for "finishing" at no charge and it's well worth the effort. I did this, and when the system was installed the dimensions and fit to the space were perfect. Overall I would say this is comparable (and in some respects superior) to the quality of California Closets who I have direct experience with. It has a better fit than the big box systems I've seen. Materials are manufactured boards with a melamine type laminate, steel rods and hangers (no plastic). You will have to do a bit of measuring and a little work with a hacksaw, but no big deal (unless you're a complete klutz and/or don't know which end of a screwdriver to use). Good value, and easy to install. Their customer service before and after the sale is terrific (I called with a couple minor install questions). Highly recommended.
