tech pen review (1/5) Jan 28, 2010 kurt c hennig annapolis ma US
  I have tried using these Rotring technical pens for drafting engineering drawings. My Rapidographs where getting old after thirty years and decided to try the newest thing on the market..What a disapointment....Purchased four (4) in various sizes and found them to be impossible to work with as they starting bleeding ink from the points once the cap was opened. changing ink cartridges and flushing the point and replacing with new cartridge did no good. Finally talked to local representative for Rotring and they sent me four more pens as replacements, and said I was loading new cartridge incorrectly...So tried again....All four new pens continued to bleed with their new cartridges...Finally put them on shelf and went back to my old stand
bys...Rapidographs.......
IMO
1.Pen points are not made to be cleaned or flushed out as can be done with Rapidograph pens.
2. Joints between point and cartridge leak ink as does joint between cartridge and pen holder.
3. Ink hardens in cartridge, and joints, and makes it difficult to disassembly pen.
4. Pen points bleed ink and are impossible to use after bleeding starts.
Pens come up short on value and usefulness.........


Pen design needs alot more work....

  Fabulous pen compared with rapidograph of days ago! The finest point is amazing -- I'll never go back to another pen again for fine printing and fine detailed art work.
