Product Variation swatches for WooCommerce

Hi there we currently have a site running your free plugin and I am looking at upgrading https://wordpress.org/plugins/product-variations-swatches-for-woocommerce/

Can you confirm the paid version will fulfill the following requirements please?

1. Show colour swatches on the shop pages
2. Ability to click through to a particular colour from the swatch
3. When selecting a colour variation (without having to also select a size) on the single product page the main product image updates to the colour chosen?
4. What’s the refund period if we trail this and it won’t do what we need it to?

Many thanks in advance
