Hasn't worked for Jared. Fountain pens are a requirement at his school, but you've never seen so many cartridge malfunctions in one set of hands. The boy was constantly covered in ink. *sigh* We gave up after 3 fountains and asked permission to send him with a rollerball until the urge to fiddle leaves him... I had to buy a pack of 5 new shirts 3 weeks into term - it was that bad :-}
