For remote release itself can be said that he is very light, small and handy,
but does not involve cheap.
The range is inside of course, since infrared light is well reflected from white walls,
phenomänal, I come out to about 8 meters.
Also behind the camera can trigger one, which is very convenient especially for long exposures,
because then you do not need to hold the remote shutter before the camera.
The only drawback in my opinion is that the pressure point is not clear.
You push it, but do not know if one pushes it gently, if you have already triggered or not.
That bothers me during long exposures little and even in group photos that should not be a problem.
Pressing namely "fast" so you can tell nothing of the.
