Soft light produced well on a big torch Metz, on which the accessory is fixed properly (head size limit of flash!). The positioning detents of the flash head is a little soft on my torch, I can only use the vertical position, the weight of the accessory, certainly minimal, making the flash head fall back in case of angular position. BUT it does not matter, because the three flexible rods contained in the diffuser enable a lower reflection by bending forward the reflector (eg for pictures at close) Note however that the flash should be powerful: the spread "absorbs" Obviously a lot of power (Guide Number Nominal my torch = 45). Anyway, I think the really interesting investment (portrait, reproductions of paintings, photo-macro with 105mm macro lens, etc.) and I really recommend, knowing that you still have a little patience for placed on the flash ... and you are watched curiously when you walk with your flash large cap! :-)
