The cons: (Are not cons if you are great with css) is the lack of design styling.
As a designer, I was not looking for a good looking menu because that's my job.
It was perfect for me because I styled it to suit my clients needs.
There was an issue using the JMS Responsives Menu's JQuery option and Yoothemes Widgetkit, but great customer service took care of the conflict.
This was just what I was looking for.
If you are in need for sliders often, the best value is the "Lifetime" package.
** Great support! - I had a question and it was answered in less than a day.
