I researched and purchased this extension for our Joomla site (v1.5) to simplify our Auth.net payment gateway. I purchased it based on the great reviews I read associated to the product and its support. Installation was a breeze. The Vendor offers Forum and Ticketing services for troubleshooting. Minor tweaks were required to get working on our site, and as I am not an expert programmer, I really didn’t know where to begin. I utilized the Support, and Ticketing services and I received same day responses by a professional with excellent troubleshooting skills, which by the way was highly proficient in the English language! (You'd be surprised how often I have to translate horrific written direction.) This experience was by far the best I’ve encountered since I began experimenting and deploying Joomla-based websites for my clients. Definitely worth the Money, and I would recommend this extension!!!
