I bought this to put a smaller MIDI-keyboard over main keyboard, which is on KS-2010 stand. The extension is very compact and easily adjustable. However, thanks to its 3 adjustment points, it isn?t that quick process, especially when compared to EX-2010?s one handle adjustment. Also, one of the mounts to the main stand doesn?t tighten so tight as the other, which adds a little wobble when playing upper keyboard with more force.
Besides that, it is simple and reliable addition for the main stand for low price.
