I just got one this past week from a fellow CPF member, and I like it a lot. I really don't find it to be uncomfortable using the mini-pen. Then again, I'm not writing any thing lengthy with it, either (full length would be more practical for that, anyway.). It writes well, but it takes a few scribbles to get the ink to start, which was unexpected, being that it has a pressurized cartridge, but I don't find it to be inconveniencing. My original thought was, "I hope it doesn't pop out and get lost", but it doesn't seem like that will happen. Originally, I thought it was a screw in pen, but it just clicks back it there. A screw in might have been a little better, though. Not sure why they didn't make it that way. So far (after a whole four days), it's great.
