The size might seem to be a bit larger at first but as you use it for a few days you'd get accustomed to it. It was working fine but within 6 months the scroll wheel stopped working and now slowly the left click is also getting deteriorated, I think it won't last long. As the cable is braided, no worries about breakage in the wire. The dpi settings are responsive but the two extra shortcut keys don't work even after installing a driver from the official site. Overall, not so good experience.
