No problems, and extremely simple logic for getting things running quickly. Fantastic.
Registration to download is completely worth it, and I for one will check into what else the developer has to offer.
The instructions in the component itself are very clear, and it is very easy to create a menu that looks like what you want it to look like. Kind of like what you click and type is what you get, WYCATIWYG... very nice.
This menu extension lacks very little, and I am sure Pro would provide whatever you are missing.
