Also, I didn't like that I needed a garbage bag looking thing to cover up my bag with in the rain. I wanted something waterproof and this bag is claims to be, the verdict is still out.
Bring a bag or a fly cover with you if you expect heavy rain - or ziplocs for important things. That bag is not waterproof. They probably just meant that it has waterproof-coated fabric. The zippers will allow water in, and at that price I can almost guarantee that the stitching/seams were not sealed with tape or sealant. Fabric alone will probably keep things dry or reasonably so in rain that isn't too heavy or prolonged.
