It was not exactly the same product as the picture I got was a "Dazzne DZ-501".
The description mentions "Material: Aluminum", while it is entirely plastic!
So for the next "line" is not great ...
However, I expected, to 11.5 this could not be aluminum.
and I am rather telling of the product anyway and quality / price ratio.
purchased for gopro, it fits perfectly the load.
perch hangs properly, either at the extension or patella, it does not move and does not rotate once in place.
by against the strap seems a little light. (Bought at the base for paragliding, I will surely change ...)
It remains to see how it will evolve over time.
