Customer support was great. My theme wouldn't let me get rid of the theme header to show the Groovy header, so I created a ticket with Groony. They responded promptly and helped me solve the issue. Regarding the product, the user interface was intuitive, particularly if you already have familiarity with WordPress menus. The video How-To resources helped me figure out anything else that was unfamiliar. Overall a great experience with the product, and the new menu looks and performs great. Very satisfied with the purchase.
