All ok, but not really satisfactory.

This flash I had bought about 2 years ago. At the time of 18,99 and even with free shipping (which was total of 5 euros cheaper than the current price). Thus, the price / performance ratio was ok.

The first couple of times when I use the flash, he also worked quite well. However, after about the fifth photo shoot session, the trigger reliability of the light sensor lies significantly (erected this flash as pasiver external flash in the room, no longer recognizes now often when the lights Hauptplitz) after. And slowly read the brightness to which he flashes. Therefore, it is now for about 1 1/2 years, around almost unused.
Had the Zuverlessigkeit and quality not so much subsided within the first 6 weeks, then the flash, 4 or even 5 star deserved. Because of his involvement, some really nice picture emerged (it really helped!).
Unfortunately, it is hardly yet usable.

Conclusion: approximately 75 to 150 x flashes long, he does a good job and it really succeed better pictures. Good times at low into the 'servo flashes' purely to sniff and test whether it is worth paying for a lot of money would be spent on an expensive flash. But it's not for a long relationship, for no more than a brief romance with a few dates.
