Slave for EX Speedlights

I recently purchased THIS optical slave from FlashZebra. It is compatible with EX flashes, most others are not. I wanted a way to fire my 2 430EX flashes without having to purchase another Cybersync receiver. I received it very quickly and am happy to say it works perfectly. I use it in the #0128 hotshoe adaptor that is listed in the above link. It's an inexpensive way to fire a 2nd flash.

Does it work outside? Even inside when you got more than you shooting it is going to get triggered by other flashes.

It probably won't work outside and, of course, the slave can't tell which flash is yours, but I got it for portrait lighting, when I will be the only one shooting. For that it will be perfect.

Thanks.

I have FlashZebra Item #0118, the PC connector version.

Of course, they have the obvious limitations all optical slaves have, except that they are compatible with EX flashes, while generic optical slaves aren't.
