The ability to work on your own bike is what distinguishes the fanatic from the frenetic in cycling. The fanatic rides with the satisfaction that his bike is tuned perfectly by his own hands, while the frenetic punishes his bike and relies on a random mechanic to fix it.

Strengths: It's Park. It works. It really can't be broken in normal use. You will have this tool for your lifetime. Enjoy. I don't feel that I can clean my bike correctly without removing the cassette for cleaning at least occasionally.
Weaknesses: None. It just works.
To remove your cassette you need this to hold the darn thing while you wrench off the lock ring. So get one. Then when you ride Chicks will dig you 'cause you've got a clean machine and you never wear a mack in the pouring rain. Very strange.
