As I unpacked the part I was a bit skeptical because of the enormous weight when it comes to handling. After a wedding with about 3000 images I can alleviate these concerns - not fold the lightning (Canon 550 EX and 430 EX II) accidentally order, yet the attachment triggers because the attachment holds bombproof. So far I have the essay not used directly as a snoot, but also the use of a diffuser, the flexibility is very pleasant. Depending on the distance and size of the target can be the light with a half hand movements concentrate more or soften. The diffuser performance itself is due to the enormous area very well. Moreover, the processing is tadelos and I bet this essay will last longer than the various softboxes, available for system flashes. Definitely recommended.
