I have been using R# for about one year. This is a very good addin to Visual Studio , I am not able to work without it anymore
It provides a lot of cool stuff. Best features ? Simplified navigation with Ctr+T and Shift+Alt+T, code inspections and great code generation.
One of the neat features I recently discovered, is switch / case generation from enum type.
Writing this switch manually would take like five minutes to write . With R# we can do this almost instantly just with Alt+Enter.
