While obviously similar...

While obviously similar to the the other Center of Gravity pens, this one seems
to have a softer grip, which is excellent, and more beveled at lower end of grip
which is nice too. Uses either the COG or older BRF15/25 refills. I agree with
previous reviewer, a switch to the Acroball refills would be terrific. But still
the best of the Ctr of Gravity pens, IMHO.
