I've done this said trigger for the halfway reasonable price bought because I thought that he is a bit better than the 0815 processed plastic things. He is also, it fits comfortably in your hand, the curled cord bothers me little have fortunately a tripod on which I can attach the shutter without which he dangles in the air if I do not stand next to the camera.
The extra functions such as timers and interval shooting I find very useful. So why only 3 stars?
Two reasons represent for me not a problem but still have a bad aftertaste.
First, the manual is not in German, but man, the functions can also watch on YouTube if you're looking a little on the model.
Secondly, can be that this only in my case but sometimes the timer zickt something and turns of its own accord from while you're on the programming of the interval, this is a bit annoying, but does not occur all too frequently.
Did the trigger now 2 weeks in use and am still with the price / performance ratio satisfied. Who is just a hobby photographer and a good remote release with a few extra features should access calm.
