Packaging
Aside from the mouse, one finds two Omron switches (D2F-01F), a set of replacement mouse feet, tweezers, quick start guide, warranty guide, and stickers in the box. Curiously, the differently colored side-button covers included with the Keris Wireless are absent.
Weight
My scale shows around 63 g (+/- 1 g), which is almost exactly in line with the weight cited by ASUS. Even though the Keris is a medium to small mouse, achieving this sort of weight without any externally visible holes is commendable, and the Keris feels very light in use indeed.
Cable
The Keris comes with a paracord-like, braided cable. Quite similar in looks and its soft feel to the charging cable of the Keris Wireless, this cable is even more flexible, easily rivaling that of the Endgame Gear XM1r or Cooler Master MM711. I did notice some imperfections in the braid, however, which is a bit disheartening to see. Its measured length is 2 m.
Feet
The feet on the Keris are pure PTFE (Teflon) feet with slightly rounded edges. Glide is very good. The ring around the sensor ensures CPI stays consistent upon applying vertical pressure. ASUS includes a set of replacement feet in the box, which is always very handy.
