What do you guys think of DeskView?

In Shark Tank Season 10 Episode 22, there was product pitched to the Sharks called DeskView. It is a window/wall-mounted standing desk that you can attach as you desire.

I have never used it and I realized it's a bit expensive. I would like to hear other peoples' opinions. For me, that's something I can buy and I feel it can be used for different purposes. What do you guys think?
