Goes together easy. Gives a nice soft light. My wireless receiver (Yongnuo RF-602) fouls the adjustmant screws so I have to mount my flash guns back to front which makes adjusting outputs fiddely but thats not the soft boxes fault. One gripe (hence only 4Stars) it's more than awkward to fold it back up.
Come on Canon why such a bad bit of design, why a two piece lens hood with brittle plastic lugs? If you want a lens hood for your nifty fifty you'll have to buy into this but I can't help feeling canon could do better. Still love my nifty fifty though.
