I bought an item that was similar to the caddy.  It was basically just a laundry bag with wheels so you could pull it instead of having to carry it.  I was very disappointed because it broke right away and was way too small.   I bought a caddy and was shocked as to how far superior the quality is!  It is waterproof, has enough capacity to store about two laundry bags, and has a rigid bottom.  The zippers work really well and will never break like they did on the other item.  Overall I would give the Caddy an A+ and recommend it to anyone.  It is a great product.
