Pro:. For the price good Verabeitungs-impression, good facilities - fully swiveling incl Macro position, Lens, Reflex cards intergriert, metal base. Function (E-TTL) with an EOS 400D very good, reliable flash exposure both directly and indirectly. Slave function ignores wish the camera pre-flash, so you can (manually) super easy conjure the wildest "Strobist" -Lichtsettings. Does knotless, even outdoors! Strobe function, manual in third stops adjustable. So a facilities have not the middle class flashes of original manufacturers usually !!
Cons: There are online tests that indicate that the manufacturer's instructions for the guide number will not be achieved, ie. that the flash is a little weak on the chest. That's not so easy to check with home agents, in the automatic mode (E-TTL) is the exposure mostly OK. More seriously for me that the operation is far from perfection. The biggest annoyance: turning by holding down the power button. Laaaaaaaanges Press. What a crock. Switching has to be fast! A slide switch would be 10x better, but probably more expensive. Then the energy-saving / sleep mode. The makes sense, but only when the flash also wakes up as soon as you tap the shutter button on the camera! That was 20 years ago when my analog EOS600 with Osram TTL flash so, but the Chinese did not get it. You have to wake up the device to flash with a single keystroke. In fact, in example. impractical for photo coverage - because you have to be ready to fire!
The manual is rudimentary, the English bumpy. German? None. If you are familiar with flash photography, but no problem. Anbetrachts the price of less than 100 EUR but you can not complain: Price / performance voices.
