First of all, have a gamer mouse will not make you a PRO but it will make easier the gaming experience. The mouse can be classified depending on the handles and for the type of sensor used.

The handles are divided into three categories:
-Palm grip

(Razer DeathAdder)

-Claw grip

(Razer Lachesis)

-Fingertip grip

(Razer Salmosa)

At the bottom of the mouse is always present the sensor, which can be optical or laser.

The optical sensor uses light to illuminate the surface to be traced. For example, the Tesoro Gungnir uses an optical sensor Avago-3090. Now, every mouse that uses a optical sensor is commonly called LED mouse or LED diode.

The laser sensor uses a diode laser to illuminate the surface to be traced. For example, the Tesoro Shrike uses a laser sensor Avago-9500. The new generation of laser sensors, uses the Doppler Effect. Laser is fired from the sensor against the surface area and the beam is reflected and mixed up with original beam. The CM Storm Sentinel Advance uses a "twin-laser" and take advantage of the Doppler Effect.


Another difference about the type of sensor, is about the surface where the mouse slide. In fact both types have some limitations, for example the optical sensor can't be used on glass and laser sensor could not work well on cloth/soft mousepad.


DPI / CPI refers to the dots per inch or counts per inch. It refers to the sensitivity of the mouse. However, the DPI / CPI does not measure the precision of the mouse, as it is often misunderstood. DPI / CPI is only the ratio between how the sensor it moves and how it moves the sensor in real life (on your mousepad).

The acceleration is the variation of the velocity from one to another point. This value is determined from the sensor, infact every sensor has its proper limitation.

The lift-off is the height measurement between the sensor and the mousepad. The optical mouse (or laser) uses the light to operate, so as long as the light is detected by the sensor, the sensor will be able to trace the movement of the mouse.

The polling rate is the frequency of refresh between your mouse and your computer. It is measured in Hertz. Usually the steps are: 125 - 250 - 500 - 1000

Memory onboard is nice feature but is not on all models. The memory basically allows you to save your profiles directly inside the mouse.

Adjustable weight also this feature is available usually only for top models. Adding or removing weights, you can have a better handling of the mouse. Like the Corsair M65 or the M40 (in picture, soon the review )




The additional weight can have different weight, size and shape.

Nice wrap-up Luca. I like it. By any chance, have you found some information on the different type of users like for example swipers and so on?

Yes, I will add some extra info
