Review on 📱 VIVO Universal VESA Mount Adapter: Ideal for Tablets, 2-in-1 Laptops, and 15.6 inch Portable Monitors - Max VESA 100x100, Adjustable Laptop Holder, Black, MOUNT-UVM02 by Jason Porter

I wanted to attach my iPad to one of the mounts on the desktop mount to use as a third display with Apple's "sidecar". It worked. The spring-loaded bottom support easily holds the iPad when rotated to landscape mode. The only issue I had was that the mount it attaches to can be rotated 180 degrees and if you rotate the wrong way from landscape to portrait the VESA arm connector will slip off your arm.
