Takes the guess work out of the preparation process, allows you to brew great coffee everywhere without the need for gooseneck kettle. It fits both Hario V02 and Origami S and I even manage to use it with Yasukiyo wooden dripper.
Once I have started reading more about thermal properties of the drippers, I have decided to try the ones with the best heat retention properties. While plastic ones excel here, they lack the beauty of the natural materials. I went with natural wood and it is indeed a piece of beauty and I reach for it more and more. So far I prefer it with Kono paper and with osmotic brewing method (by Cafec).
Simplify is a not simply breawer, but when you had the correct recipe the cup.of coffee is complex sweet beauty
