Packaging
Aside from the mouse, one finds a quick start guide in the box.
Weight
My scale shows around 74 g (+/- 1 g), which is slightly less than the weight cited by MSI. Compared to the Razer DeathAdder V3, the GM51 weighs substantially more, though it does feature RGB lighting, unlike the DeathAdder V3. A decent weight.
Cable
The Clutch GM51 Lightweight comes with a paracord-like, braided cable. In terms of flexibility, this one easily beats the 8K offerings from Razer or Corsair, and is roughly on par with the cables of other 8000 Hz polling rate mice such as the Zaunkoenig M2K or Atompalm Hydrogen, which are commonly regarded as having the most flexible cables of 8000 Hz mice. Its measured length is 1.95 m, and the USB connector is gold-plated.
Feet
The feet on the Clutch GM51 Lightweight are white-dyed pure PTFE (Teflon) feet with slightly rounded edges. Glide is very good and thickness average. The ring around the sensor ensures CPI stays consistent upon applying vertical pressure.
