I know for a fact that Woo Ninjas work extremely hard! They responded to my issues within a reasonable amount of time. My experience working with them has been positive and pleasant. Their responses and support are good and very professional whether it related to WooCommerce general issues or their extensions. They are good at prioritizing issues because when I reported urgent issues their response was quicker compare to less urgent problems. They have been helpful also at providing a quick fix for third party extensions they advertise on their site and for which support is marginal or not present.
Awesome work Ninjas!
