At best, a stopgap

Negatives:
- Any instruction (not even a sketch, anything)
- In the hole of the "mechanism" of height adjustment, a small metal spring is installed. I had to remove (pinch off), so I was able to insert the locking pin.
- Locking the Höhenverstelung is almost too short and can not be saved
- Shaky status; only at the lowest setting halfway stable. A tube end is significantly bent.
- Poor support for keyboard. My Yamaha EZ220 is far from stable on
- Slight scratches in several places

Overall rating:
Meets cheaper China-junk of all clichés. As a stopgap useful but nothing more. I will make today in stores in search of something useful. This part of me goes by the joy of the new keyboard.

Update as of 14.1.14:
Today I got my new keyboard stand. Namely, the original Yamaha called L-2C. Thus, the keyboard is like a one. So I imagine that. In addition, it has under the keyboard more legroom, since the crossbar is designed at the back. Including delivery from Germany to Austria the part has cost me 55.50 EUR, which is significantly more than the estimated cost-part, which cost 32.08 EUR. But rather 20 EUR more spent on a good product, I can only say. One advantage of the L-2C is also a disadvantage: it is connected with 3 screws using the keyboard. Who wants his keyboard so "jiffy" stand up and put away, is perhaps better served with the local cheap folding part.
