Comments about Interfit Photographic Interfit Photographic Strobies, 24" x 24" (60cm x 60cm) Folded Softbox with Bracket Kit:

Although the softbox itself is of excellent quality and seems sturdy enough to survive anything, the bracket that comes with it could not be tightened enough to prevent the ball head from moving. This allowed the softbox to fall to a downward angle. The softbox is too heavy for this bracket. I returned the item with no hassle to Adorama. This product was fresh on the market when I bought it so maybe Interfit has solved the problem by now. Also, I have a Nikon SB-600 that I attached to the bracket along with a Yongnuo radio transmitter and found that it doesn't fit well with that set up, even with trying to jury-rig it, the flash head couldn't be completely inside the back opening of the softbox, leading to loss of lighting.
