The build quality is, as was the case Flashbender reflector, very good. Only criticism: The joining of reflector and diffuser with Velcro and snaps is a bit fiddly. If you have both but first together, the diffuser provides beautiful, almost shadowless light that comes across very well in both portrait, as well as for product shoots. Sure, a good softbox does not replace the diffuser, but one must also be a shoot on location not herhumschleppen much with it.
