I am satisfied with its function, but too much cables
It's been only a week since I started using sidetrack. I purchased two external screens together. Its setup is easy. But my macbook air wasn't compatible to use both screens at the same time. I needed to purchased an USBC Docking station for that reason. Even with that device, I had to use 2 sets of cables together (hdmi and type c) to be able to work with 2 screens at the same time. So there is a lot of cables hanging around. But it functions well. It is a helpful device if you have to use to many windows at the same time.
