The assembly also succeed alone without any problems in a few minutes. The material makes a good impression. The Velcro fasteners hold reliably. Only the adapter for Hensel flash I find something "sharp-edged". When Händling I always feel that I mind the hand could cut me. Happened so far nothing. The illumination with grazing light is uniform and is the original Hensel Softbix in every way. For the relatively low price, this Softbox is thoroughly recommended.
