Top-tier pen and support
The Mark One is a fantastic pen, but the customer service from Studio Neat is what truly sets them apart. I recently needed some help with the pen after a few months of use, and the team (specifically John) was incredibly responsive and generous in sorting it out immediately. The product is top quality, and the company truly cares about its customers. Buy with confidence.

Great design, push button needs to be steel as well.
I love the look and design of the Mark One, the push button mechanism feels great to click. The push button should've been made from steel as well, the soft aluminum is already pretty worn looking just after a few days of use.

Too slippery to write comfortably.
The pen is "wonderful", except it's slippery when held. Too slippery to write with. It's hard to write with because it's hard to keep a solid grip on the very smooth surface. There needs to be some jimping or knurling where one holds the pen. I wrapped mine in a rubber pencil grip, but I've mostly stopped using it. Very disappointing that Studio Neat elevated form over functionality.
