I liked that it was easy to use, very flexible, and could be customized in so many ways. It also has several different skins you can choose from as well. The only thing I didn't like about this plugin was how buggy it was when using IE 11. Sometimes if you refreshed your page or used another browser, all of a sudden some menus would disappear. Also sometimes it took awhile for the menu items to load after clicking them. So far everything seems fine with this but I am not sure what version they released recently since we just started using it. We are currently working on an ecommerce website that requires a lot of customization options. This allows us to do exactly that without having to spend countless hours customizing each item by hand.
