For a while, this was the ONLY capless, retractable rollerball pen on  the market.  But with a lightweight brushed metal barrel and a larger than usual liquid refill, this is still my favorite, with smooth writing until the very last line of ink.  The spring-loaded clip that prevents this from rolling down your table also retracts flush with the barrel when the pen is in use.
