This Metz flash has the following positive characteristics: good handling, clear display, display easy to use (see). The performance is ok, function with my Nikon in TTL mode ok Cons: when used in a report in the "M" mode and mostly bounce flash is sometime very hot the device. When changing the batteries, I could barely touch the batteries, so hot they came out of the machine. After 300 flash (TTL), it may happen that the communication to the camera does not always work = turns off briefly. That can be embarrassing in practice quite. I know from previous Metz devices not - but obviously has now also saved somewhere. For professional use you should as far as possible do not have a second device while - just in case and so that the Metz can cool down ........ (perhaps Yongnuo .... ???)
