I love the plugin over all. It's super easy to use - much easier than doing manual redirects and much more graceful. The UI is pretty intuitive and well built as well.
It has one kind of glaring omission for the more experienced webmaster - the ability to omit particular URLS. It becomes an issue with any plugin that requires variables on the end of the url - or for custom UTM analytics campaigns. It permanently redirects them to a non-variable page url, effectively breaking the plugin and stopping your campaigns from being logged in analytics. I had to manually edit the script (see the support forums) to account for those.
