Millenium KS-2010 EX

Good but but does not inspire confidence at all for expensive equipment

Good for adding some midi controllers or a simple keyboard, or some score books etc, but I would not trust it to put expensive or/and heavy equipment on this, not that much stable.

Not the greatest solution

Kind of difficult to set up without an extra set of hands, and it's hard to make it fit smaller 3-octave synths. Instead I'd recommend to get a full set like a Fun Generation universal stand + extension, or a Tuff stands KS-54, which are sturdier and more reliable

Very restrictive

Bought with the Millenium stand. Went on easily but needed three hands to set it. It is not wide enough to use when the stand is wide open for a seated person, the arms are at an angle pointing inwards so the supports on the front do not nod the upper keyboard very well. May work better for a standing performance where the lower stand is not set so wide. My Yamaha keyboard on top has gaps on the underside to I've had to put a pad under it to stop it wobbling. Very difficult to level as the teeth, which stop it from slipping, are fixed.

steady and good stability as a third tier.

Solid as a rock

This works with the 1010 stand top.

Not the best.

One screw did not fit right in the frame. So if you plan to move your stand around for tour or something, you will not be able to fold it again.

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.

Janky

Not a great piece of kit, was bent out of shape when it arrived and it didn't fit the keyboard stand it was supposed to. Wouldn't really recommend it.

Delivers

It holds really good and looks like it's going to

Inexpensive Solution

It's good, no doubt about it, but it seems as if many people, including myself, may have had to be a bit rough with it to make it work. I use it to stand a Korg on top of a Roland FP4, and it hasn't moved since installation. It didn't quite fit properly so I had to get out the hammer and make some slight adjustments, but overall I would recommend it as a good option. I haven't taken it on the road yet so I cannot comment on its durability on tour. Inexpensive and definitely worth the money - but you may have a tough time getting it on your keyboard stand.
