Its great and flexible

It is a very flexible slider and their support is fantastic. With layers you can control your slider easily. Since it is not just a basic slider, there is a slight learning curve but that’s ok.
Their support team was pretty fast about replying the questions.
I gave them 4 stars, because of the limits of the free version is pretty annoying especially if you want to embed videos or custom html into your sliders but the free version is good enough for taking care of simple stuff.
