Summary: AWESOME mouse! The profiles change the color of the LED's on the mouse. Better DPI with laser and kicked my older Logitech laser mouse in the dust. Software is easy to use and is need to assign buttons and DPI. Also the cord can be placed in 3 different areas leading from the mouse's front. Noticeable difference in playing shooting games, very spot on. Need a new mouse? Don't pass this one up! Also if you are into art on the computer, this mouse has GREAT accuracy!
