For —
  • Ebonite feed — rare below several hundred dollars — and credited with the flow and lack of hard starts
  • Huge piston capacity, months on a fill
  • Excellent out-of-box writing reported
  • Nibs interchange with the Asvine V800
  • #8 nib at well under $100
  • Brass piston mechanism, large capacity
  • Ebonite feed on some versions
Against —
  • Clip is very stiff to lift
  • Grip flange slightly sharp
  • Too long and heavy posted for most hands
  • Piston disassembly needs a dedicated wrench
  • No branding on the cap at all
  • Big and heavy enough to divide opinion
  • Nib QC lottery applies
