Works perfectly with my Vivitar 283 and my Vivitar 285HV. I have one for each. Never had a misfire with them.
Works perfectly with my Vivitar 283 & my Vivitar 285HV. Works through walls as well. Haven't had the chance to really test it's range yet. Exactly what a I needed for strobist work.
I got 5 of these (all new)in a job lot. Only three worked with my big Metz 45s and 60s. One just kept triggering all the time by itself, and the other wouldn't fire at all. But then I found that the two "failures" worked consistently and perfectly with other much smaller flashes that the successful three were inconsistent with. I have now married the five slaves up with respective flashes for perfectly consistent results, each flash and slave having colour coded dots. Well you can't do better than working perfectly I suppose, but I would not mind understanding it. Could it be something to do with voltages in the flash PC leads? Note changing leads (and I have heaps) had no effect on the slave/flash partnerships. I let one of my associates have one, and as expected, he had to try them all, after which like me, he is also happy. My recommendation is that if you only want one, take your flash unit to the shop.
Never had any problems with it, works well.
so I got this little unit with a vivitar flash and the results are really not reliable. Sometimes it works and than for some unknown reason it doesn't work. Even is the trigger flash is right in front of the optical slave.
So I suggest stay away from this cheap thing.
