- The rail on which the ring is mounted for receiving the soft box is too long. But this problem, almost all softboxes this design.
- The hot shoe is horrible. If you screw this a little too far to fall apart the pieces and you can look for the two small springs. Even me is the maintenance of the flash is not scary. I removed it and replaced with a plastic base of lightning, which I have attached to the screw of the hot shoe. I do not trust the plastic base to significantly more than the supplied flash shoe. He holds flash + shutter least reliable.
All in all, with benevolence and with regard to the price for me four star.
