I bought the tablet stand from AirTurn. (AirTurn MANOS and portable tablet and mic stand from AirTurn). It works OK. When I first got it, I accidentally unscrewed the arm knobs and couldn't get the MANOS back together. The arm knob has a spring that is installed at the factory so I had to get a replacement stand. There was a warning in the manual but I didn't understand which knob that was.
One thing that always bothered me is that to use my iPad Pro 12.9 in portrait mode the clamps are on the side not underneath the iPad. That doesn't seem like that would be secure but so far it works fine.
I must admit that most times I use my orchestra stand with the iPad Pro. The orchestra stand works well for switching between the iPad Pro and paper sheet music and to me it seems more secure.
I also have the AirTurn DUO 500 bluetooth foot pedal and that works great for turning pages on my iPad.
