Personally I paid just over 2 and pdfs free at this price why deprive yourself? The object seems indeed a bit light, but I'm careful and I will do everything to make it last. It was delivered in a well protected but the envelope folding a flap was wrong. Nothing irreversible, I folded it properly, it is perfect now. Once again, given the price we must not be too demanding. It is indeed a little time to prepare before assembling and ditto for the back, in the end it fits perfectly on my Nikon Speedlight SB-700. Side effects: it softens the flash light when the head is pointed directly at the subject, but who does that with a cobra? ASAP is used with a cobra's head swiveled toward the ceiling or to a wall, this is the best diffuser that is, it is imperative to limit the use of direct flash, and this diffuser is not miracle . In portrait mode, the shaded range is still there, the cottage cheese effect disappears but the colors are less punchy (there it is a matter of taste). I made many tests with and without diffuser in exactly the same conditions and without changing the parameters of shots, the verdict is clear: live flash is better but it's still ugly because of the direct flash, bounce flash (bounce) it changes nothing if not a loss in brightness (logical but is easily corrected in the expo parameters). HOWEVER: outdoors where direct flash is required fault wall and ceiling: a softer light, softer shadows: very well. And personally I find my account in macro initiation, the diffuser allows to move the light source to the end of the lens, the more Sb-700 tilts a bit down, so I can enlighten closer to the target without being disturbed by it. Cheaper than a ring flash for beginners!
In conclusion: it indoors absolutely no substitute for effective direction of the flashgun to achieve a diffuse and creative lighting (check instead on technical rebound and fill-in for me a successful photo must forget that were used, a flash). Outdoor and macro / proxy photo mode, it blurs the harshness flash "naked", the light source approach before objo for 2 (or 3) there really should not be deprived of improve the quality of your reports. I highly recommend.
