The tray does what is intended however it is a surprisingly clunky affair for dropping down and managing the cables. It’s ok if this is a one off but if you intend to add and remove items regularly (such as a laptop power brick) then you might want to consider other options. Opening the tray involves unclipping some plastic clips from either end of the tray at the same time. The tray then drops open to allow you to add and remove items. The tray is substantial and coupled with the weight of any power strips and supplies in the tray at the time means the drop is sudden and loud. The desk it attaches to is very slick. This tray is not. On the plus side, it’s large and hides all the cables away neatly. If you only need to set this up once, then you’ll be happy. A mixed bag in that regard.
