tompoland How do you find the Porlex for filter? I had one in my very early espresso-only days as a travel grinder but abandonded it quite quickly.
Indeed, grinding for espresso on the Porlex (or other ceramic burr hand grinder) for typical dose is a real chore, I have used it for single doses of around 10g.
For filter, it’s normal/typical just the time that it (the Hario and the Rhino) take to grind, manually, is a big downside. At one time I made 30g Clever brews in the office, it was a sweaty race against the kettle (4 min to boil) to get the dose ground! It was replaced with the first iteration of the Lido grinder.
Porlex is fine for smaller doses though, but it’s difficult to see, if anyone had a faster grinder, why they’d bother going back to it, other than for a light travel grinder.
