Packaging
Aside from the mouse, one finds a quick start guide and USB Type-A to Type-C cable in the box. The cable is wrapped around an oval to ensure no kinking.
Weight
My scale shows around 63 g (+/- 1 g), which is slightly more than the weight cited by SteelSeries. Compared to the Prime, the Prime Mini loses 6 g, which is roughly what can be expected considering the difference in size. An excellent weight, especially considering the fact that no holes have been used to achieve it.
Cable
The Prime Mini comes with a paracord-like, detachable USB Type-A to Type-C cable. It is way more flexible than the Rival 5 cable and roughly on par with the Aerox 3 Wireless charging cable, but can't quite compete with the likes of Endgame Gear XM1r or HyperX Pulsefire Haste. Though the cable lacks an anchor for further stabilization, the connector sits tight, and I didn't experience any disconnects during play. Its measured length is 2 m.
Feet
The feet on the Prime Mini are white-dyed pure PTFE (Teflon) feet. Glide is very good. The ring around the sensor ensures CPI stay consistent upon applying vertical pressure. Indents next to the feet make them easier to remove.
