Review on Yoassi Universal 360°Rotatable Anti Wobble iPad 1/2/3/4/5, Mini 1/2/3/4, Air 1/2, Pro 9.7 - Enhanced Stability and Flexible Viewing by Gary Duncan

Works great! I paired it with a cheap Pro[Master] Basic Light Stand (LS-1) and it worked perfectly. I use it with my 12.9 inch iPad Pro in a Logitech iPad Slim Combo case (keyboard removed). The iPad is very easy to remove from the stand and is really secure on the stand. One note, when assembling this mount, the ring is not actually screwed, just hold it between the mount and the ball joint, they snap slightly and then you can twist the ring to pull everything together.
