The light diffusion plate was initially very difficult for my device. After a few passages to this problem, however, had resolved itself.
Some reviews complain about the thumbscrew on the hot shoe as opposed to the quick release of the original. Whether it's a lack everyone can decide for themselves. Function does it and that's the main thing.
The desöfteren criticized acoustic feedback ("the beeping in readiness") I see rather than forward, as a disadvantage. I like to have a quick response if the device is ready to flash or not without first having to draufschauen. Who does not like it can switch off at any time.
A German manual was not there. But can ergoogeln quickly. As an accessory, a decent bag and a foot for standing is. While the latter requires some strength to put it, but he also holds good.
In some reviews of inadequate support is criticized occasionally. Let's be honest, when I really need this? Either the device is still in warranty, the dealer is responsible, or it is no longer in the warranty, then a new purchase is usually cheaper than a repair.
All in all, nothing to complain about. Clear recommendation and a perfect score.
