Frustrating user experience

I really dont know what made me buy this app for 15€ but I regret it ever since. While it actually does work as a second screen, it has connection problems, excessive lag and graphic errors all over the place. I definitely cannot use it to get proper work done. Worst of all, it only works as a second screen, not a third. Would NOT recommend!!!!
