Packaging
Aside from the mouse, one finds a USB Type-C to Type-A charging cable, wireless dongle, wireless extender, quick start guide, and set of stickers in the sturdy box.
Weight
My scale shows around 77 g (+/- 1 g), which is exactly in line with the weight cited by Razer. For comparison, the Viper Ultimate, which is larger and likewise features dock compatibility, RGB lighting, and rubber side grips, weighs 74 g. A decent weight overall.
Cable
The Cobra Pro comes with a 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 appears slightly stiffer than the charging cables of the Basilisk V3 Pro and DeathAdder V3 Pro, thus likewise falling short of the charging cable of recent ASUS ROG mice releases, for instance. Accordingly, playing while charging is mostly possible on the Cobra Pro without feeling too restricted. Since the cable supports the HyperPolling Wireless Dongle, shielding equivalent to that of a high-speed wired mouse is present. 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. A storage compartment for the dongle is found on the underside of the mouse.
Feet
The feet on the Cobra Pro 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.
Mouse Dock Pro
The Mouse Dock Pro has two main functions. First, it comes with the functionality of the HyperPolling Wireless Dongle integrated, enabling a polling rate of up to 4000 Hz in 2.4 GHz wireless operation. Second, the Mouse Dock Pro serves as a charging dock. To that end, the Mouse Dock Pro utilizes induction without any direct contacts. The Mouse Dock Pro has a puck included which replaces the one installed on the Cobra Pro by default. The mouse then magnetically attaches to the dock, and the RGB lighting can be configured such that it displays the current battery level, though this requires the mouse to be turned on in 2.4 GHz wireless mode. Furthermore, the RGB lighting will continue to be on even after the PC has been shut down. The Mouse Dock Pro is compatible with both the Cobra Pro, Naga V2 Pro, and Basilisk V3 Pro, and is available for $69.99.
