That's very nice to know. However, I've just stumbled upon Nissin's Di866 II. Does anyone have experience with it? People are saying it blows the YN-568 II out of water!
The nissin flash is a well built thing that is competing with the canon 580EXII while the YN568 is not competing in the same class as is reflected in the price.
I have two YN560 (originals, not I, II or III) and two YN568 II. I can't rave enough about them, especially for the price. Only problem that I have with them is the YN568 II's I have suffer from the battery door problem, but they have replaced this since Oct 2013 I believe.
I use old RF-602 for manual triggers when needed, but usually use the Canon 90ex flash as a commander for ETTL, HSS, and remote power control and it all works beautifully. Never had a misfire or any kind of overheating issues.
