The best mouse

1-LED 2-LASER

In the area of the sensibility, the laser mouse is 20 times more sensitive than the optical mouse.
The laser mouse is faster than optical mouse and it is more exact.

The LED mouse doesn't work well on subtle surfaces such as highly polished wood, shiny or slick surfaces. It can also have problems over rough surfaces.

The laser mouse is more expensive than the LED mouse.

My opinion is that James must buy a Laser mouse because it is the best mouse.
