Review on Maximize Your Workspace with SideTrak Attachable Portable Kickstand - Compatible with 14", 1920X1080, 60Hz and Lightweight by Timothy Pollack

I paid $350 for a 14" May 2021. It's great for my work from home working in my chair. Any issues I had initially I overcame with technical workarounds like cutting a piece out a $1 styrofoam cube bought at a dollar store that keeps the weight of the extra screen from closing the laptop when I lean back.Sometimes the side screen gets knocked off but it's secured by a cable connecting it to connects to the laptop preventing it from falling to the floor Daily use and it seems very reliable to me.
