I have it running on multiple production environments, so I know it works. The fix for the fatal error was released yesterday.
Combination with add-to-cart has broken before after different WooCommerce releases; because they have changed the internal handling of add-to-cart. For now the most robust option is using fill_cart. fill_cart has another advantage; if the customer clicks the url for a second time; the products will not be added again.
A fix for add-to-cart in combination with the most recent versions of WooCommerce will be released soon. I still must test it with the versions between 2.3.0 and 2.6.7 (and 2.7 beta).
