The Sensor

Here is a close-up shot of the optical sensor used in the Fantasy Mini Mouse.

As mentioned earlier, this optical sensor has a resolution of 400 CPI (Counts Per Inch). There is no mention of the tracking speed but comparable mice with a similar resolution have a tracking speed of 1500 fps.

The USB-to-PS/2 Converter

Although notebooks have dispensed with PS/2 ports and moved entirely to USB ports, the included USB-to-PS/2 converter is still a welcomed addition. You never know when you may need to use this mouse with a computer that does not have any free USB ports!
