Have you ever tried using one of those tiny ultra-portable USB mice while traveling? They seem like a great idea at first, but in practice they lead to more hand cramping than productivity. That’s what’s so ingenious about the ring-style fingertip USB optical mouse—it’s incredibly small and lets you keep your hand in a comfortable position. Slip it on your index finger and switch seamlessly between mousing and typing. Perfect for traveling professionals who find themselves working in cramped spaces like buses and planes, or for anyone who wants to pretend to be a cyborg with a laser attachment built into their hand. Pew pew.
