Processing and functionality of the remote switch themselves seem ok, especially for the price. Unfortunately, it is not working. The cable I've pushed all the way into the corresponding socket of my OM-D. Sometimes it is still sharp, sometimes not. Trigger does not work at. The cord is very shaky in the bush, he probably does not have the necessary contact. This seems to be a fundamental problem. Because of this, definitely not recommended. That complements: I have complained about the trigger in my photo, Berlin. My Photo responded immediately and sent a new trigger. On the return of the defective timer has waived my photo. Class service! The new trigger is working as expected, in this regard, there is nothing to complain about. However, the connection to the camera is quite labile matter. Before therefore, due to the great price:-timer now *** (3 stars) My photo as a trader: ***** (5 stars)!
