Packaging

Aside from the mouse, one finds a USB Type-A to Type-C charging cable, wireless extender, set of replacement feet, sticker, and quick start guide in the box.

Weight

My scale shows around 58 g (+/- 1 g), which is exactly in line with the weight cited by Darmoshark. For comparison, the slightly smaller and likewise RGB and hole-less Razer Viper V2 Pro weighs exactly the same. An excellent weight.

Cable

The M3 comes with a paracord-like, braided charging cable (USB Type-A to Type-C). In terms of flexibility, this one is above average, to where playing while charging is possible without feeling overly restricted. Its measured length is 1.95 m, and a ferrite bead is attached.

The charging cable also functions as an extension cable, if used in conjunction with the wireless extender, which can be used to keep the distance between dongle and mouse as short as possible. A storage compartment for the dongle can be found on the underside of the mouse.

Feet

The feet on the M3 are white-dyed pure PTFE (Teflon) feet with slightly rounded edges. Glide is very good, but it appears that either the base isn't entirely flat or the application imperfect, as some scratchiness can be experienced on certain parts of the mouse pad. Thickness is average. The ring around the sensor ensures CPI stays consistent upon applying vertical pressure. A set of replacement feet is included in the box.
