Review on 📱 Versatile Tablet Stand for Bed: Adjustable, Foldable, and Rotatable- iPad/iPhoneX/N-Switch Compatible (White, 4.5~12.9 Inches) by Christopher Rodriguez

The hinge at the end of the lever is not strong enough to hold the Samsung Galaxy Tab A7 at a 90 degree angle. The photos show the iPad being held at a 90 degree angle, but I doubt the connection is strong enough to hold a 9" or larger tablet. A plastic nut is used to tighten the ball joint and bolts are used to tighten all other connections. But there is nothing to tighten the joint where the end slides into a notch that should provide a 90 degree angle. Additional support is needed, such as Velcro.
