First off, I mostly agree with you. I have encountered nastier refills than the spacepen medium but it is sets the bar pretty low for writing experience. Huge issues with blobbing. As others have mentioned the spacepen fine, is a much better refill. It is no where near as good as say a Pilot G2 Gel but it at least makes it a usable writing tool. However, and it is a huge, gigantic, massive however, nothing else has the "its just writes" factor. I don't write in the rain much, nor upsidedown, nor in space, but I do have them stashed in various places and when I pick them up they just plain work. Left in my truck for months in the dead of a Canadian winter... it just writes; in the boiling heat (believe it of not it can get stupid hot up here too) of summer, it just writes. Discovered in a desk drawer after years of abandonment, it just writes. No other refill I have tried comes close to the "it just writes" performance of the spacepen refill no matter the environment it lives in and that is what makes it amazing. I love ultrafine gel refills (0.38 - 0.25 mm) but they pretty much suck in the longevity department. I have a number of pens in my rotation, mostly filled with Pilot G2 0.38 mm refills, and it is rare that I will get to the end of a refill before it has issues. I have spacepens that are 10+ years old that still work. In my lifelong quest for a perfect pen, I have stopped using one as my edc, as the refill does suck for actually writing legibly, but I still keep one in my truck for taking notes.
