In their effort to create the most ergonomic and comfortable mouse of all time, Logitech studied a movement that human beings have been using to greet one another for centuries: the common handshake.
Like a handshake, the cordless Logitech MX Vertical Advanced Ergonomic Mouse keeps your wrist at a 57-degree vertical angle. This natural position can reduce overall muscular strain by 10 percent helping to alleviate or even eliminate the symptoms of carpal tunnel syndrome and other repetitive motion injuries.
Better yet, the MX Mouse features advanced optical tracking and steadfast cursor speed that demands 4 times less hand movement to reduce overall joint stress and muscle fatigue. All the while, your hand is cradled neatly by this revolutionary mouse, your thumb lying comfortably on its own rest and your palm resting secure against a lightly textured but elegantly contoured rubber surface.
