Sturdy, movable, flexible. A great way to organize keyboards and stuff in small spaces. Wholeheartedly recommended!
I added a couple of short arms to the top row and a 30 cm deep wooden board at the lower row which stays behind a Novation SL 16 mk2 keyboard.
Now I have (top to bottom): 1) Korg MS-20 and Korg ARP Odyssey module, 2) Arturia Microfreak, Arturia Spark LE, Arturia Keystep, Behringer Model-D, USB hub, Korg SQ-1, 3) Novation SL 61 mk2, IK Multimedia iLoud micro monitors, MOTU AVB Ultralite, 2x powerstrips. Amazing!
