Packaging, Weight, Cable and Feet
Along with the mouse, one finds a quick start guide, sticker, the charging cable, and the wireless receiver in the box.
My scale shows around 122 g (+/- 1 g), which is slightly less than the 124 g cited by Redragon. By no means a light mouse, the M686 Vampire Elite places below average—it's lighter than the Corsair Dark Core RGB Pro or Logitech G604, but can't compare in terms of buttons or features with either. The same goes for the ASUS ROG Chakram, which weighs the same but comes with way more features. Even the ASUS ROG Pugio II has more features and weighs 20 g less.
The included cable (USB Type-A to Type-C) serves two purposes. It is used for charging the M686 Vampire Elite and can be connected to the mouse for wired use. In terms of flexibility, it can only be described as very stiff. Its length is 1.80 m (measured). The cable has an attached ferrite bead, which helps reduce signal noise.
The feet on the M686 Vampire Elite are standard black-dyed PTFE (Teflon) feet. Glide is perfectly fine. There's a thin protective film on the feet which ought to be removed before use.
