I think the Viper rollerball works well on many levels: it looks good, it handles well (easy to grip and hold for extended writing sessions and note taking), it caps securely, and it's sized well for a wide variety of hands. It hasn't displaced my now-32 year old Lamy 2000 ballpoint, but the Viper's magnetic snap cap and satisfying writing experience makes me reach for it more and more often. IMO, that's high praise. Maintain your writing experience by using high quality refills.
