today's test at EOS 600D: works just as smoothly and reliably as described!
Please note:
the Ready light shows the willingness to work with red and not as accustomed with Green on (for whatever reason)
Reloading during the February takes a little too long for the 3rd flash in continuous shooting, better trigger with frame 3 x, then it works
Old batteries do not even try, the light remains green, eneloops work perfectly
Not high-end but I've already experienced worse battery cover
"User Manual" in English, not a real problem, the menu navigation is simple and understandable, the internet can also be found several explanatory movies.
Comes in a practical protective bag and with pedestal (for use as a slave) - what more could you want !?
Conclusion:
This flash does exactly what is advertised and praised, not more but also no less. In the first test and reliably without crashing or malfunctioning. The results of exposure are neat, with the star key (Test flash u. AE lock) a bit too bright images but that can regulate everything. Communication with the two designated cameras works perfectly. Sorry, no high-speed Synchro, that would be really still a desirable option, but there probably just not enough power from all .... Perhaps in Version III ?!
Pleasantly surprised and completely satisfied, I will use the flash as a holiday flash next to my 270 EX II and also to assist in wireless deployment.
My absolute recommendation!
