Hey lefties, I'm sorry you were born with that uh, disability, but it's okay because Elecom has designed a mouse just for you! Aren't you special? Actually, this mouse is better for a lefty sharing a computer with a normal human being, err, righty. This beautiful canary yellow mouse includes a switch that will swap the mouse buttons for left or right handed individuals on the fly. The symmetrical design also ensures that the mouse will fit nicely in either hand.
M-EKURDR, the ambidextrous mouse [Akihabara]
(Just kidding, lefties. Me love you long time.)
