I'm planning a several week trip in my VW camper to Baja. As my traveling companion is particular about breakfast, I figured coffee was going to be awfully important. I will trust Tonx for our beans but I wanted to make certain her morning brew was special. GSI's hand operated conical burr grinder and a 1L insulated press seemed a great answer.
Last night, I tried the grinder. It is simple and easy to operate, as a grinder should be. Remove the handle and turn the wing-nut to adjust coarseness. A few cranks 'n tweaks and I had it just right. The grinder is cleverly designed to fit on top of most round coffee presses. It slides around a bit on the GSI Glacier 1L press that I paired it with, but is no problem to use.
The press worked as expected and the insulation had coffee drinkable one hour later. The Tonx coffee was delicious.
