C# Refactory???

A coworker introduced me to the concept of "refactoring tools" lastnight by showing me the C# Refactory tool at Xtreme-Simplicity.net.

This is just what the doctor ordered!

I don't know how many times I have performed the actions this tool purportedly automates.  I plan to download the Eval unit tonight, and play with it.

I would appreciate feedback from anyone who might have tried this tool or similar ones before...
