As a new photographer, there are many small details that are critical but sometimes get missed. I placed an order on the website and the next day received a call checking that I had the correct strobe as well as that I would need to order the ring as well. As I was trying to attach the adaptor to the AD300, I had some trouble figuring it out. So after a quick web search, of course I found this video on the StrobePro site and low and behold...I am now ready to shoot. Thanks guys, everything from the ordering experience, to the fast shipping and finally the support with these videos.
