Packaging
Aside from the mouse, one finds an AA-battery, a wireless dongle, quick start guide, and set of stickers in the box.
Weight
Using the included AA-battery, my scale shows around 80 g (+/- 1 g), and 57 g without the battery, which is slightly less than the weight cited by Razer. For comparison, the DeathAdder V2 X Hyperspeed weighs 79 g without any battery, the more comparable ASUS TUF M4 Wireless weighs 62 g without any battery, and 85 g with an AA-battery. Accordingly, the Viper V3 Hyperspeed is among the lightest battery-driven wireless mice of its size category.
As the Viper V3 Hyperspeed lacks a wireless extender, the wireless dongle needs to be plugged directly into a USB port. When doing so, as per
Intel's documentation, it is strongly recommended not to use a USB 3.x port, as ports of this type may introduce interference adversely affecting wireless operation. A storage compartment for the wireless dongle is located below the battery slot.
Feet
The feet on the Viper V3 Hyperspeed 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.
