This extension is okay if not using the widget or block snippet in CMS page
If you only want to create this slider through the plugin's "Product Sliders" section and add it to all pages, or categories, then this plugin is really good and provides a lot of options.
It falls short, however, if you want to insert it as a widget, or block within a CMS page (Or template).
A lot of the options aren't available through the widget or block, such as showing the product price, add to cart button etc. Basically, most of what makes the plugin useful is missing.
There's also, currently several bugs that actually break it when using a block snippet.
On the plus side, the code is open source, so it can be modified. I've fixed the breaking bugs, and added some of the missing options into the block snippet functionality, and have a pull request waiting for them to merge in. So hopefully the next release will have a few of these things fixed and it can get a higher ranking.
