Just picked up a set of these wireless flash triggers from cowboy studios off Amazon. I am excited for the possibilities they can create in my portrait and wedding photography. Off camera flash is advantageous for many reasons not the least of which is more flattering and natural light since shadows are revealed and not removed.

First impressions make me think they will not be as durable as the pocket wizards but if they are as good of performers then in y opinion it may not be an issue.
