I've got a Porlex mini that was my only grinder for ages but since I got an electric grinder I only use the Porlex when I'm camping. The electric grinder has a more consistent grind.
I'm going to be traveling soon for an extended period but having been spoilt with the electric grinder I don't want to go back to full time with the Porlex. I'd like a hand grinder that can match my electric grinder for consistency.
The only main difference I've heard between the two is that the handle on the Rhino is less likely to routinely fall off.
(Owner of 8-year old Porlex who's handle has never fallen off).
Would go for the Rhino myself.
