I bought this trigger for the second time. First held over 10 years, but several times he's been caught fell off me or at the booth of waves that I will not take his Exitus foul him. A short slip with a cheaper replica confirmed to me just again: "who buys cheap buys twice". So yet again spend a little more, but get a prized investment. I can operate the shutter blind, so it was me as clear as day that the replica that is to be 100% equal allegedly, yet was quite different, immediately went back. I must be able to rely 100% on the trigger, no time for experiments.
I use the shutter almost exclusively bracketing (where I can also change the time really fast by hand) and long exposures. Even mobile apps like iOShutter and Triggertrap are there not quite as ego imagine. But they are a good temporary help when the shutter button is nevertheless times broken.
