KS-2010 EX : Impossible to fit properly on any stand

I was planning to use this extension maily in rehearsal and live, to fit my Prophet or midi keyboard on top of my Nord Stage.

The build quality is pretty low, but that was expected at this price range.

The extension does not fit on larger double-X stands. I had to use a smaller, less stable one in order to fit this extension. But even then, it is impossible to have the 2 arms well aligned so that the top keyboard sits in place. There is always a gap and it is extremely uncomfortable to play when the keyboard is constantly bouncing up and down.

I have tried really hard fitting this extension on several stands and it was never stable. I do not recommend this to anybody for any use.
