I like this extension. It's genuinely free, and the free version is full featured. You can pay a few Euros to get a really nice extension which integrates into the menu editor, but you don't have to. As a menu system, it looks nice, and it works well. What I liked was the support. I got very fast and accurate help: the author visited my staging site and did a Firebug inspection to point out my problem (which was not due to his extension). He did this even before I paid for the easy config option. The extension is not necessary, but it supports the developer and makes life easier. So a really great experience.
