Addendum early November.
After two months, two springs have no longer work properly, it has rust formed and thus to clamp the spring or to pop out of the holder out. After repeated pressing of the spring and clean the clamping function could be restored. This I have not seen for stainless steel products. Strange that this occurs only at 2 parentheses, only 1 of 2 secured on the weather side.
For outdoor use partial functionality, do not talk overnight and certainly not be out in the rain!
Therefore only 2 stars.
