Review on Fotodiox EZ-Pro Strip Softbox 12X56 With Speedring For Alien Bees B400, B800 & B1600 Strobe Lights by Joe Unruh

The included speedring fits my Alien Bees B400 perfectly. There's no gap between the included speedring and the Alien Bees clamps like shown in some of the "customer images".The "outer diffusive cover" measures 52x10" and this is the real effective area of this softbox.Description says "Rotation speeding ring with thumb screw lock" (singular) -- i.e. there are 3 regular phillips screws plus 1 thumb screw lock holding the speed ring in place. While this description is accurate, it is deceiving since I need to loosen 3 of the screws (not one!) to release the speed ring, the one included thumb screw is pointless. Btw, the 4th (regular) screw is included the carrying bag.Overall, good quality for the price. Did not by the matching grid due to negative reviews.
