Just received this product the other day, and right out of the box I am very impressed with it. The first thing i did was test its capabilities by filtering about 12oz of water from one glass to another, which katadyn recommends doing anyway in order to clear out any ceramic dust. The flow rate I experienced was similiar to what i read on the companies website, which i believe is 0.5 liter per m
