At first I wanted to stand again return, as he was apparently warped and the views had diagonal an altitude difference of about 2 cm. Nothing with the screws could be set, I have the struts aligned with gentle force against each other, and after about five minutes, the stand was stable.
The height can be adjusted easily and quickly and should each provide a comfortable posture. In the highest position of the stator is however relatively fragile.
+ Does the keyboard found his place, he is sufficiently stable
+ No odor of rubber pads
- Had to be made until firmly emphatically only
- The regular switching / transport to unstable
- The highest catch too shaky
My conclusion: the keyboard is in its place and does not have to be constantly moved or changed, the stand quite fulfilled its purpose. Who surrounded or transported regularly, will have little joy, because he must be re-stabilized after each collapse.
