Packaging, Weight, Cable, and Feet

Packaging

Aside from the mouse, one finds a USB Type-C to Type-A charging cable, full-speed wireless dongle, wireless extender, quick start guide, and a pre-cut set of grip tape for the main buttons and sides in the sturdy box.

Weight

My scale shows around 58 g (+/- 1 g), which is 1 g lower than the weight cited by Razer for the white version; the black version has a claimed weight 1 g lower. Compared to the previous Viper Ultimate in black, the Viper V2 Pro in black lost an impressive 17 g, without resorting to externally visible holes, and only doing away with the right set of side buttons and the built-in rubber side grips, an impressive achievement. The Viper V2 Pro even manages to beat the Logitech G Pro X Superlight at 63 g or HyperX Pulsefire Haste Wireless at 60 g, the latter of which has a hex-shell construction.

Cable

The Viper V2 Pro comes with a soft and flexible braided USB Type-A to Type-C charging cable. There is no anchor at the mouse-end of the cable, so the cable may come loose during use, though it is unlikely given how firm the connection is. In terms of flexibility, this one isn't quite on the level of the recent ASUS ROG or Glorious charging cables, but is significantly improved over previous, stiffer Razer charging cables. Accordingly, the Viper V2 Pro can be used as if it were a wired mouse with barely if any perceivable difference in terms of handling compared to an exclusively wired mouse. Since the cable supports the HyperPolling Wireless Dongle, shielding equivalent to that of a high-speed wired mouse is used. The cable is 1.80 m long.

The charging cable also functions as an extension cable when used with the wireless extender. The wireless extender can be used to keep the distance between dongle and mouse as short as possible. Since the mouse itself lacks a storage compartment for the dongle, the extender can also simply be used as something to attach the dongle to, reducing the likelihood of the dongle being lost when traveling.

Feet

The feet on the Viper V2 Pro are non-dyed PTFE (Teflon) feet with slightly rounded edges. Glide is very good. The ring around the sensor ensures CPI stay consistent upon applying vertical pressure. Compared to previous Viper iterations, both size and shape of the feet are different.
