There is a diffuser, which can be folded by turning and clamped on itself when it is released. Proven technology, works well and seems to be pretty knick sure. In other reviews called stubborn behavior I can not confirm, maybe it just needs a little practice. The shiny reflectors and the black are combined in a shell that is drawn through the permeable and closes with a zipper. This involves a few drawbacks: First, you can the semi-transparent screen not with eg using the gold reflector together, except you put the gold shell just go somewhere, if you can, but then it is not yet tensioned and reflects quite uncontrollably.. In addition, the glossy coatings are likely with frequent wrinkles break (my impression is they have not yet long enough to tell) and the zippers hook something.
BUT:
Despite its small flaws, these reflectors combination is recommended for the price. For the simultaneous use can buy another if the material breaks through the wrinkles, you can leave it open. By comparison, a Sunbounce Sunmover does certainly not much more and costs four times.
