Review on 📱 Aqonsie Gooseneck Phone Holder Bed Mount Clip with 360° Rotation- Flexible & Hard Arm Bracket for iPad, Tablet, 4-14" Phones - Foldable Cell Phone Stand for Desk, Bed, Sofa, Kitchen, Office (Gold) by Therealwesley Shaw

Fits what I need. I have a 14 inch secondary screen and it is 8.5 inches. This juuust is suitable for assembly. It shakes/vibrates as I type and shakes back and forth, so I'll definitely update this review depending on how long it takes. but this was the only mount I could find that works on a portable desk in hotel rooms/travelling and remote work. 4/5 due to shake/vibration. I can feel if they have a steel side tablet mount or metal won't move that much otherwise it works fine.
