Packaging
Aside from the mouse, one finds a quick start guide and detachable USB Type-C to Type-A cable in the box.
Weight
My scale shows around 66 g (+/- 1 g), which is exactly in line with the weight cited by SteelSeries. Compared to the Rival 5, the Aerox 5 is losing a whopping 20 g, which is quite impressive. The Aerox 5 also manages to weigh 5 g less than the Glorious Model I while being bigger and featuring a similar level of holes. Overall, an excellent weight and achievement.
Cable
The Aerox 5 comes with a paracord-like, detachable USB Type-C to Type-A 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 2.05 m.
Feet
The feet on the Aerox 5 are non-dyed pure PTFE (Teflon) feet with slightly rounded edges. Glide is excellent and thickness average. Upon closer inspection, one can see that the feet appear more translucent than most others, which is due to little to no dye being used. The ring around the sensor ensures CPI stay consistent upon applying vertical pressure.
