Packaging

Aside from the mouse, one finds a wireless extender, wireless dongle, AA-battery, and quick start guide in the box.

Weight

Without a battery, my scale shows around 52 g (+/- 1 g), while with the included AA-battery, my scale shows around 75 g, both figures of which are largely in line with those cited by Cooler Master. Despite being much larger, the MM311 weighs less than the Razer Orochi V2 at 58 g, and weighs significantly less than the slightly smaller SteelSeries Rival 3 Wireless at 85 g and also less than the similarly sized ASUS TUF M4 Wireless at 62 g. That said, weight balance isn't ideal, as the MM311 is very back-heavy, which becomes more noticeable due to the lower starting weight.

Cable

Similarly to the Ninjutso Katana Superlight, the MM311 comes with a dedicated extender cable for the wireless dongle to ensure optimal connectivity. Its measured length is 1.70 m.

Feet

The feet on the MM311 are white-dyed pure PTFE (Teflon) feet with slightly rounded edges. Glide is very good and thickness average.
