I believe the optical finger mouse is a key component to a successful multi-tasker as it allows your fingers never to leave the keyboard so you can crank through those blog posts – o maybe a mobile environment where a flat surface isn’t available.
USB Fever is set to release an all new 2.4Ghz wireless Optical Finger Mouse with USB dongle at just $27. Include a wireless keyboard and become the ultimate mobile office worrier.
The finger mouse comes with 3 ring sizes and great resolution of 1000dpi along with a rechargeable lithium-ion battery which powers up via USB cable.
