Packaging
Aside from the mouse, one finds a carrying pouch, quick start guide, and sticker in the box.
Weight
My scale shows around 59 g (+/- 1 g), which is exactly in line with the weight cited by Razer. Compared to the DeathAdder V3 Pro, the V3 is only marginally lighter at 59 g. A competitor such as the Corsair Sabre RGB Pro at 72 g is soundly beaten, though the DeathAdder V3 does lack RGB lighting. An excellent weight.
Cable
The DeathAdder V3 comes with a paracord-like, braided cable. Compared to the cable of the Viper 8K, flexibility is much improved and superior to the cables used on Corsair's 8000 Hz mice, despite the continued presence of additional shielding to ensure signal integrity at 8000 Hz. As such, when seeking to replace the stock cable, it is strongly recommended to use one with similarly strong shielding as unexpected behavior may otherwise be introduced, especially if external sources of interference, such as EMI, are present. The cable is 1.80 m long.
Feet
The feet on the DeathAdder V3 are non-dyed pure PTFE (Teflon) feet with slightly rounded edges. Glide is excellent and thickness average. The ring around the sensor ensures CPI stay consistent upon applying vertical pressure.
