Review on OCTA Lynx Tablet Mount: Secure & Versatile Stand for iPad, Galaxy, Surface, and More by Douglas Jakab

This is the only one I've found for the 13 inch iPad Pro. You can't have a cover for it to work, and it's FIRM, but it works really well (you have to stretch it all the way. At first I thought it wouldn't work). I would give 5 stars. if I didn't have to take the lid off to use it. but if you have a smaller iPad, it doesn't even affect you. The neck piece isn't very long but I think they make longer versions that will work with the tote bag. Once you mount it on any surface, it becomes a reliable auto focus. Ideal for musicians to attach to music stands.
