1. It offers a free version. You can download the free version and try it out 100%, instead of a demo page where you don't get to know the extension very well, especially when it comes to customizing the component to fit your template.
2. Lightweight and Easy to customize.
3. Simple and straightforward.
4. Pro version comes with full support.
5. Affordable and fair price.
6. It does what it is supposed to do. Just need to adjust the look, and some minor things here and there.
I give this extension 5 stars! Excellent job,
