The Flexpert doesn't disappoint. It frees me from having to be near the ink bottle for long periods of time. If I want to draw or sketch outdoors, I just grab my Osprey pen with the Flexpert nib unit. The Flexpert can be easily taken apart for cleaning, or for swapping out a new Zebra G nib. But the important thing is that the feed was designed to be mated with the Zebra G. I don't have to bend anything into place in order for it to work; it works right out of the box.
I suppose I'll continue using my dip pens, but there's really no need any longer. The Flexpert, mated with either the Milano or the Scholar, is just as comfortable and versitile in the hand as any pen holder I've used in the past.
The other important thing to know is that the owner of Osprey Pens takes Customer Service to a new level. I discovered that when we had a Zoom conference to resolve an issue. Her suggestion solved the problem pretty quickly, and I'm back in action.
