I've been a few months using this screen now with the Phottix Varos BG Multi-Function Flash Shoe Umbrella Holder mostly on the lamp stand, sometimes on the tripod. As a light source I have the Nikon SB700 and Yongnuo YN568EX. Use in portrait photography, product photography but also for macros, mostly indoor but also sometimes Outdoor. The screen is a nice, soft fill light or main light. Also outdoors is the SB700 with the screen enough light to brighten, with the Yongnuo it needs to go even better, it has a higher LZ (but I got it new, so no experience). The screen and the flashes I have always with the right light. I use the Walimex WT-806 lamp tripods set with carrying case, as you can easily to put it in a carrying case.
Linkage and Tension has shown so far no weaknesses, I am very satisfied. I would buy the screen at any time, therefore, a clear recommendation and 5 *****
