I have owned both Hario's generic handgrinders and I swear by Porlex. It's higher quality construction and easier to hold and use. It also snaps right into Aeropress for travel so they are a perfect combination. If you get one, get the mini as there's really no reason to buy the large one.

Which of the two Hario grinders are you using? I have the mini mill, and use it daily for my aeropress without any annoyance. But you need to have a quite coarse grind (no finer than filter grind) and do an inverted brew. Grinding out something like espresso fine coffee is a pain.

Is that the Skerton? I find that annoying at times even with relatively large hands. Wondered if the Hario MINI MILL SLIM would be better.

That hario grinder is a piece of shit. Takes me at least 7 minutes to hand grind nonstop a Chemex (yielding 2.5 cups)/
