I bought 2 of these units and like them a lot.  I needed more space in my closet but didn't want to spend a fortune on a "closet system".  They were easy to put together without tools and hold a lot of things, including shoes, skirts and shirts, leaving room for longer items like dresses to hang elsewhere.  My only criticism is that the plastic clips that hold the poles to your existing wire shelving have flimsy hinges that look like they'll break apart if  they're opened and closed too often, so I recommend placing the unit where you're sure you want it before clipping it to the shelving.
