He does what he is: Button half-press -> focusing; Button press -> trigger; Tab upward move (and put the camera on Bulb) -> Any long exposure time. However, I find the button a little "spongy", honestly I would have because a better feel wanted / expected. The function does not diminish but ultimately and for that price the product is absolutely fine! The original Canon makes according to a statement from a friend a more significant impression, however, that costs even more ... and the cable is much shorter, which was for me then but a decisive factor. All in all I would order this remote trigger again; Buy recommendation.
