I wanted a portable brew grinder for my work and didn't want to drop that much money on it so I took advantage of the early bird price on the feld2. I ordered mid-November and received today. No cosmetic scratches or blemishes. Took me a couple minutes to figure out but pretty straightforward. It zeroes out at 1 and is looking like my brew grind will be around 3 to 3.25 rotations, somewhere on the 1-3 mark.
No need for any extra grip support or any kind of thumb grip. Grinding light roast beans is pretty easy with a loose grip, even on a fine espresso grind. This is my first small burr hand grinder so nothing to compare to, but I'm surprised at how easy it is to grind (although it does take a lot of rotations). The grinding feel is smooth and reminds me of the mahlgut, almost like you're shaving the beans.
Consistency of grind looks solid.
Catch cup stays on very well while grinding but is also easy to remove.
Handle and lid come off no problem, but not an issue with coming off while grinding.
No burr wobble on my unit. Seems pretty rock solid.
I haven't made any coffee with it yet, but based on look and feel, so far I've got nothing to complain about. The build seems excellent and the design seems well executed.
