The Logitech MX 1100 is a new cordless right-handed only mouse. Released in August 2008, the MX 1100 is the first general purpose consumer mouse with adjustable sensitivity settings, and the first in recent history of higher quality mice from Logitech to re-impliment a clickable scroll wheel. Featuring 10 fully programmable buttons, a high sensitivity 1600 dpi laser and a super fast scrolling option, the MX 1100 transmits at 2.4GHz, allowing for a super fast response time with less interference.
