KS-2010 EX : Does the job but could be better

I bouth this for my 49 key midi keyboard that weights 3 kg and while the stand does hold it up securely there are a couple of problems (at least with mine):

1) my keyboard doesn't sit flat. I fixed that with a little bit of padding on one corner

2) I wish the vertical posts could be taller. it doesn't make sense, since normally a keyboard stand would be set-up quite wide and because of that the vertical posts of this extension would have a narrower angle resulting in less vertical height

3) those plastic things that hold the keyboard from sliding down aren't mounted in the same angle and one is not holding my keyboard at all, but since I use the midi keyboard very lightly it's not that big of a deal for me.

4) maybe I didn't notice but I'm pretty sure that the nuts for those bolts that you use to mount it to a stand were missing

All in all, for the price and for what I need it works great!
