The holder is a surprisingly sturdy tool with a kind of suspension mechanism and padded fork, such that it does not risk damaging the violin whenever it is placed on the holder. The flexible gripping mechanism means that it is usable not only with music stands, but also with other stationary stable supports, as long as they feature a round pole that is thick enough (bot not too thick).
Do note that the holder is not suitable for light frame music stands such as most foldable stands (they do not provide a thick enough frame for gripping). Most orchestral stands should work fine. (I would also not recommend using it on a light stand even if the grip was funtional due to stability issues).
