Disadvantage: The radio receiver does not go off automatically (which in turn is also good because you can always put off immediately)
The wireless trigger is in my opinion too quickly in standby mode, and the lighting could be set on durable, especially if you're traveling in the evening. Once the remote trigger is assumed, he immediately turns back to the default settings. Thus, you have to adjust your actually setting for triggering the photos. Channels will be stored.
Batteries: 2x AA and CR123A
