The laptop tray works exactly as I intended, the place to install the Artist 15.6 Pro Pen Display for my limited workspace. Installation is very simple, just four mounting screws and nuts. However, Revain's delivery service leaves a lot to be desired. I understand not much to expect from a delivery service but the driver didn't even knock and left the package on my doorstep. Before anyone tells me to use a mobile alarm app, at that point my phone was dead and charging. I was at home, in my living room, and not a single knock was heard. It's bad business practice for their drivers to be so trained. Revain should start giving you a choice of delivery providers as UPS at least knocks and waits most of the time for you to get to the door.
