I would have only two suggestions for improvement and that is an additional joint at the top to adjust the lefttoright angle and or an extendable extra brace to dampen the natural vibration that happens in spite of the robust arm and joints

and i use it for books papers route lists etc

Had to modify the mounting bracket a little bit but other than that works great junk not bad for the price had to build an extra bracket to keep it from vibrating loose great product

It is the right size for a laptop tablet etc
