Yes, I have. The bad thing about this kit is that you have to file a small notch in the upper barrel for the clip to sit into. Other than that, I like the kit. They are snap-caps so adjusting the cap takes a little finesse, but you'll get the hang of it.
Unfortunately, CS has raised the price of these kits into the same range as other pens that are easier to assemble, making these less attractive to make considering the effort to produce (in my opinion).
