Color comes down, for size adjustment dismantled one music stand into several parts

As an amateur musician I am used to normal music stand. Accordingly, I was pleasantly surprised that this music stand has two fixed metal rods with springs that can not fly away the sheet music even in light winds (only relevant when major central portfolios or in windy conditions I find).

It is also relatively stable and is slightly larger in the folded state as I am used to it.
What I do not like is the fact that an extension of the music rest (ie if one sets itself up, enlarged / lengthening yes the music stand), there is no limit or maximum stop. Correspondingly, each then has a part of the music rest in the one and the other part in the other hand and has to laboriously try the parts zusammenzubekommen again. This should have been able to otherwise solve.

But who wants to use it in a sitting position and who do not mind if part goes down the color of the music stand, which can buy that.
