Computer peripherals like keyboards and mice have to stay on a table to function. When you move to a couch, the keyboard could sit on your lap, but the mouse is tricky. It needs a flat and smooth surface in order to work.
Razer Turret is a combo of a wireless mechanical keyboard and a gaming mouse that is not only suitable on a desktop, but also on a couch.
Thanks to its solid retractable mousepad that is hidden inside the keyboard, now the mouse has a perfectly smooth place to rest and function.
