Have almost only good experiences with the Funkauslöser made great part! Nothing to complain about, except for an exceptional situation in which the knob very stupid and jammed for a while nothing more was itself to trigger. And of course in the middle of a photo session, where I did not have much time for the recordings. Because that just must never happen with such a device, an asterisk deduction. The button was then restarts properly and it never occurred since. That's why it remains in good rating with four stars. But you have to watch out the cable slipping ever slightly a bit in the plug points and then is nothing more and you wonder what's going on - at best between every now and check if everything is tight!
