Personally I think this is a great tool for PC gaming on the couch. Build quality is great, and I think the size is perfect.
Some down sides are: 1) Only compatible with one model of Corsair gaming keyboard. It is not a bad one, but you don't have choice in the mechanical switches and it only has blue LEDs. Also it lacks the numpad, but I think it's a logical design choice to keep the whole board within a reasonable width.
2) No wrist rests. So lengthier game sessions might be bad for your wrists.
3) If you take your hand off the mouse, it might slide off the board.
