Great replacement nib
I've enjoyed JoWo nibs in the past, and this EF didn't disappoint. Used it to rescue a PenBBS bulkfiller that was writing way too wetly. This nib behaves excellently in the pen, and is true to the labeled line width. Tines were well aligned. Ran it briefly across a tri-grit smoothing stick to reduce a little feedback, and it's writing on par with my finest steel nib pens. Glad I made the small investment in this nib to return this pen to my normal rotation.
