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 109 g (+/- 1 g), and 86 g without the battery, which is slightly less than the weight cited by Razer. For comparison, the Basilisk V3 Pro with its internal battery weighs 113 g, whereas the Logitech G604 weighs around 137 g with an AA-battery. A decent weight overall.

As the Basilisk V3 X 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 right next to the battery slot.

Feet

The feet on the Basilisk V3 X 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.
