Used this for a small business that has 100+ products (handcrafted jewelry). I created a basic site for her and setup the plugin (it's not complicated for basic setup!)
The plugin has lots of options to work with.
One criticism. WooCommerce is 'technically' responsive although on smaller screens the images don't display professionally as everything looks crammed together.
Experiencing some difficulty getting products with different attributes and pricing to display all the entered data on the live site.
