First impression: box was pretty big and came with a lot of pieces. Everything was well organized inside, and the instructions were very clear. I had a new closet in my young daughter's room within 2 hours! I recommend really taking the time to plan out how you want the closet laid out, as you'll have to drill holes in the wall for the drywall mounts. 

We LOVE this closet system, and plan on buying a few to redo our master room closet.

Pros: Clear instructions, tons of customization, great value
Cons: Must be comfortable with power tools
