The flash trigger works just fine with my 25 year old Vivitar-storm-in flash. Have the flash mounted next to the camera on an equally old camera bracket with handle and on a big family celebration all guests portrays flash pivoted upward and scattered paper before lightning; so no red eyes, no rework, great light! The camera's flash I had defused with scattered paper and runtergeregelt, to trigger the slave flash handed the. The only downside was, and I had not thought of before: Whenever another guest photographed (and flashed) was also my go! This meant often just before the shot: no juice just there because of lightning had to load again. I then because shaded optical shutter by hand and removed the finger just before the shutter releases. Even outdoors in daylight no chance because the reflection lacked triggers the flash. Résumé, to be photographed when to companies and seriously out: better to take a radio trigger. Otherwise: good price, good device!
