So far I have been working with Lastolite "Ezyboxen", but added myself out of curiosity, the Firefly. Yepp, the thing is still much better than the competitor product! The build quality is impeccable, the building less than a minute, everything is very solid and stable. Unlike Ezybox a joint is integrated into the system flash holder, saves an additional purchase of (eg) the Manfrotto Panhead. The light is quite fantastic, me a bit gentler than the Lastolite counterpart. The adjusting rail for the system flash, in my case the big Nikon SB 900, is long enough that if necessary. Still a radio receiver takes place among them.
This is in my opinion the best softbox for system flashes, moreover, for very fair price. My supplier, AC photo has delivered in record time. Yesterday afternoon ordered today delivered early at 10:00 via DHL. Many Thanks.
