Cyber Snipa Intelliscope Laser Gaming Mouse
 

The Cyber Snipa Intelliscope gaming mouse comes at a price tag of under $25, but
includes a lot of functions one would usually only find in mice twice as expensive.
These include an on-the-fly DPI switch, programmable buttons and perfect left handed
gamer support. The only real shortcoming is the somewhat bloated and buggy software.
If you are willing to look past that, the mouse itself will certainly not
disappoint.
