I find this very pleasant filler and use it currently almost daily. I still write a lot with hand, it was very important to me to find an easily workable and lightweight digital pen. The filler of Schneider fulfilled this Kritrien very good, Although I find the cap a bit oversized but that bothers me only in so far that it takes a lot of space in my pencil case, but also because I got used to. I find the spring of the strength of M just a bit thick, but also may be due only to my subjetiven assessment.
