A optical or laser mouse?

My laser mouse tend to consume less energy than my regular mouse but that’s may be its better design, and most laser mouse uses Bluetooth technology for wireless.

Gaming mouse is better but laser is better than regular optical mouse, you won't see any difference when gaming. but on some surface the laser mouse works better, like a desk with plastic cover.

For gaming; use the gaming mouse, which I think uses laser optics.

The Logitech MX518 is pretty darn good. It's a bit older, and it's optical rather than laser, but it's still an excellent mouse.
