I bought this pen awhile back, and loved the way it wrote. However, when the original ink cartridge gave out, I bought some generic "fits several pens" type refills. There was too much play in the point when they wrote, even if they were functional. The tip holding the rollerball moved just too much. So, I set the pen aside, and rarely used it. Somewhere on here I discovered a site that carried "original equipment" Schmidt refills. So, I ordered a set. Needless to say, the pen is now in my pocket pretty regularly now. It rivals the G2 and the 207 I've been using lately. And besides, despite having to post the cap (rather than "click it"), it is much cooler looking (see below), and quite a bit heftier. Just thought I'd share.

I have the silver model.
