Packaging

Aside from the mouse, one finds three two-part weights, a quick start guide, safety information guide, and warranty guide inside the box.

Weight

My scale shows around 98 g (+/- 1 g), which is almost exactly in line with the weight cited by Corsair. Three two-part weights each weighing roughly 5.5 g are included, making it possible to bring the weight up to 118 g (rounded). While not exceedingly heavy, the M65 RGB Ultra definitely isn't lightweight, no doubt owing mostly to the solid aluminium frame.

Cable

The M65 RGB Ultra features a paracord-like, braided cable. It is very similar (if not identical) to the Sabre RGB Pro cable. As such, flexibility is above average, which isn't amazing, but better than the Razer Viper 8K or EVGA X17 cables. Compared to the cables of non-8000 Hz mice, the cable on the M65 RGB Ultra has more shielding to ensure signal integrity at 8000 Hz. As such, when replacing the stock cable, using one with similarly strong shielding is strongly recommended as unexpected behavior may otherwise be introduced, especially if external sources of interference, such as EMI, are present. Its measured length is 1.80 m.

Feet

The feet on the M65 RGB Ultra are regular black-dyed PTFE (Teflon) feet. Glide is decent.
