From the handling ago, the holder is completely okay. It can be folded small and comes with a small flat pocket. With the 3 screws (2 long under the Bowens recording to connect recording and slides, and 1 screw for blocking the slide end back) you can put him in a minute together. The range of motion of the carriage is sufficient for a large radio trigger and a big flash, I tested the combination YN-622 + YN-568, which goes smoothly.
All in all, a strong buy recommendation, when his studio Lichtformer sometimes want to use on the go.
