I know. I had decided to use the Vietnamese phin, but after 2 weeks I went back to the drawing board.
I loved the taste of the Vietnamese phin, but cleaning it out after every use was a pain in the water supply. The drip was tasty, but there was the problem with having paper filters, an added expense. The french press was a cleaning problem, and it didn’t do as well as the others in making small amounts of coffee. The Aero Press is the winner. The coffee is very good, there is a metal screen for the filter and the cleaning is a snap. The slight down side of the Aero is that it isn’t as tiny as the phin. But that is minor.
