it will work with all canon ex series flash, but no way to say for sure how many time it will work before failure.
given the fact that those i bought only comes with 7days 1 to 1 exchange, i strongly advice u to get from ShutterCentral who is offering 6mth 1 to 1 exchange, since the price is roughly about the same.
i have only myself to blame for not doing enough research regarding the exchange period. a lesson learn:sweatsm::sweatsm:.
