Packaging, Weight, Cable, and Feet

Packaging

Aside from the mouse, one finds a quick-start guide in the box.

Weight

My scale shows around 123 g (+/- 1 g), which is largely in line with the weight EVGA cites. The X15 definitely doesn't qualify as lightweight, though this is neither unexpected nor particularly worth criticizing for an MMO mouse. For comparison, the Corsair Scimitar RGB Elite weighs 118 g and Redragon M913 Impact Elite 129 g, though the latter is wireless.

Cable

The X15 features a regular braided cable. Compared to the cables of non-8000 Hz mice, the cable on the X15 has more shielding to ensure signal integrity at 8000 Hz. As such, when replacing the stock cable, it is strongly recommended to use one with similarly strong shielding as unexpected behavior may otherwise be introduced, especially if external sources of interference, such as EMI, are present. Virtually identical to the X17 cable, the cable of the X15 too is quite a bit worse in terms of flexibility than that of the Razer Viper 8K. Its measured length is 2 m.

Feet

The feet on the X15 are regular black-dyed PTFE (Teflon) feet. Glide is fine. The ring around the sensor ensures CPI stays consistent upon applying vertical pressure.
