The best mouse

Laser mouse

The laser mouse is more sensitive than the Led mouse. It works better in subtle surfaces such as higtly polished wood, shiny or slick. It also works better on rough surfaces, so the laser is better than the LED.

LED mouse

The LED mouse is worse than the optical mouse because it is less sensitive.

So I advise you to buy a laser mouse.
