There are times that we want that great immersion coffee, but our schedule doesn't have the room for the prep and nuances of the legendary Hario V60. The Hario Switch Immersion Dripper is all about that. This Hario dripper is extremely easy to use and gives you a dialed in cup every time. Pour and wait....it's that easy. A stainless ball on the bottom of the dripper blocks the water from dripping, and after 2 minutes, a beautiful 200ml of coffee is ready to go! By pushing down the switch it lifts the ball, releasing the coffee and let it drip into a mug. Filters not included. Uses Hario V60 Filters size 02
