Official WooCommerce Products Carossel Slider
There are multiple Product Sliders out there, but none are optimised properly. Or finding one that is, takes a lot of time.
The WC shortcodes show images in an optimised way (based on Woocommerce Image Thumbnail size).
So if there was an addon to buy, that enabled it to use the default sizes, with simply modifications for height, style of navigation etc, it would be magic.
If it turned out not to work, WC's refund policy is perfect, so we have no issues of it isn't quite right.
Unlike other plugins that are not so good.
