I've got an OXO that has worked great since I bought it in 2014. It's an ugly piece of white plastic, but it's efficient, unfussy, ergonomic, and adjustable.
I had this until I lost it in a move. Decided to upgrade to a Peugeot. The Peugeot is way better.
I've got this OXO version and it has worked great too. The singular down-side being that its rubbery bottom tends to grip too tightly to surfaces so it falls over instead of sliding.
This makes sense due to that end being the gripped side during use.

I also own the aforementioned Unicorn. I use it for "bulk black pepper" grinding and use this model for finer grinds of white and green pepper.
