Noodler's pens are great, they come with a flex nib and are meant to be easily disassembled. The Konrad is a piston filler which is very uncommon for a pen in its price range. The only problem with this pen is that the nib and feed are free to slide around a little. This can be beneficial for adjusting the flow of ink, but after writing awhile or keeping it in a pocket, it can slide out of alignment. It doesn't significantly hurt the flow, but it is noticeable.
