A4 Tech G9-555FX V Track Padless Mouse

When think of A4Tech, automatically think of affordable mice that gets the job done without trying to be fancy or anything. A4Tech launched its latest mice technology, the V-Track, which is supposed to be better or at least rival Microsoft’s Bluetrack and Logitech’s Darkfield technology.
The V-Track technology allows A4Tech’s mice to function properly on virtually any surface without the need of a pad.

It even works on transparent or reflective glass, furry rugs or carpets, and on uneven surfaces. And it will even work properly on your skin or even your hair, not that you would want to do that. But for those who uses their laptop with their dog beside them, yep you can use your dog as a dogpad.Behind the scenes, optical mice uses a slanted light path to the surface while V-Track technology uses a vertical reinforced light for a more precise output even on soft 3D fabrics and uneven surfaces. Compared to Microsoft’s BlueTrack, V-Tracks main advantage is that it works properly on uneven or 3D surfaces due to the vertical light it use to illuminate the surface.It also uses a short light path which should lower power consumption giving you more juice out of your battery when using a wireless mouse. V-Track also has a tiny lens aperture compared to traditional optical mice and this prevents dust accumulation on V-Track powered mice
They had some of these V-Track mice for us to test on a variety of surfaces.While it tracks properly in furry rugs, the furs themselves hamper the movement of the mouse so it kinda defeats the purpose. You could use it on bed or carpet without a problem though.
This equipped with a special button that allows you attach functions like taking a screenshot, or marking the screen (useful for presenting), launching a file or an app, etc.

G9-555FX with another button that allows you to change the dpi (up to 2000) in an instant. Very useful for gaming.
