Hario has made heatproof laboratory glass since 1921, and its name means “the king of glass”. The coffee range grew out of that, which explains why its products behave like instruments rather than appliances.
The V60 is the reference pour-over and earns it by refusing to help you. One large hole and full-height spiral ribs mean water leaves as fast as you pour it in — the dripper regulates nothing, so the cup is entirely a product of your pour. Done well, the clarity is unmatched at any price. Done carelessly, it is genuinely bad coffee.
The Switch is the more interesting product and the more useful one. It is a V60 with a valve in the bottom, so you can close it, let the coffee steep like a French press, then open it and drain through paper. You get immersion’s forgiveness and paper’s clarity, and pour rate stops being the variable that decides everything. If you can only own one manual brewer, that is the one.
Filters are proprietary and cheap. Buy two boxes, because running out on a Sunday is a specific kind of annoyance and nothing else substitutes properly.
