Both are very easy on a spigot, the top of a lighting tripod mount. The flash picture is made of metal, so the flash sits tightly than in a plastic receptacle.
When Delamaxhalterung the flash sideways clamped with a clamping screw. When Walimexhalterung (this holder), there is not. Therefore, the flash is inserted as in the hot shoe of the camera and must be secured over the thumbscrew. Flashes with quick release (spine), such as the SB-900 sit not completely fixed here. Therefore, the holder ore is suitable for lightning with screw connection. In the track there is a rubber in which the quick release may take, but I can pick up the flash anyway ...
For my taste, the flash is not exactly at the center of the screen but ehr slightly above. With a reasonable zoom position of the reflector, however, that should not be noticeable in the photo.
My conclusion: A solid support for amateur photographers. The flash has but a knurled feature to keep you safe. Keeping the aforementioned plastic screws if they are attracted with reason. No one can buy Platik and expect quality metal. Then the money must be invested in a metal holder.
Who buys a light stand to should make sure that the segments are attenuated. If the tripod times collapses protects a spring or an air cushion in the extract the expensive flash before impact. For example Walimex BT 806th
