Packaging

Aside from the mouse, one finds a charging cable (USB Type-A to Type-C), quick start guide, and sticker in the box.

Weight

My scale shows around 96 g (+/- 1 g), which definitely isn't lightweight, but not entirely out of line with the competition, either. For comparison, the Razer DeathAdder V2 Pro weighs in at 87 g, ASUS ROG Gladius III at 89 g, and ROCCAT Kain 200 at 105 g. However, none of these feature externally visible holes, whereas the M808 Storm Pro does, albeit only across the top.

Cable

The M808 Storm Pro comes with a regular braided charging cable (Type-A to Type-C). As far as flexibility goes, this cable can only be described as ultra-stiff and thus unfit for gaming purposes. The cable has a ferrite bead attached, which reduces signal noise. Its measured length is 1.80 m.

As the M808 Storm Pro lacks a wireless extender, the wireless dongle needs to be plugged directly into a USB port. 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 on the underside of the mouse.

Feet

The feet on the M808 Storm Pro are standard black-dyed PTFE (Teflon) feet. There is a protective film on both skates that ought to be removed before use. Glide is perfectly fine.
