This brewer has three exit holes, just like the Kalita Wave except that the holes are in a row. The dripper looks like a Melitta and takes the same fan-shaped/tuncated cone filter papers, but the inside surface is the same as the classic "Kalita-style" 101/102/103 dripper favoured in Japanese Kissaten. Unlike the Melitta, the Kalita has high ribs everywhere - the Melitta has no ribs up top and much less pronounced ribs near/at the bottom, and has one hole instead of the Kalita's three. The brewer is arguably best used with for medium and darker roasts and a slow constant drip feed to keep the bed constantly near the level of the height of the dripper (not the height of the filter paper). This plastic version is a nice way to try out this brewing method as well as being essentially unbreakable and so great for travel.
