Packaging
Aside from the mouse, one finds a quick start guide in the box.
Weight
My scale shows around 73 g (+/- 1 g), which is exactly in line with the weight cited by XPG. While the Slingshot is a large mouse, the Glorious Model D isn't much smaller, yet manages to weigh 5 g less while having fewer holes. The Pulsar Xlite even manages to get down to 48 g, albeit without much of a bottom plate. A decent weight overall.
Cable
The Slingshot comes with a paracord-like, braided cable. In terms of flexibility, the cable is average. I'd say it's slightly better than the cable used by older VAXEE mice or the older Xtrfy M4 and M42 cables, albeit not by much. The cable of the more recent Zowie EC3-C is undoubtedly more flexible. Its measured length is 1.65 m. A ferrite bead is attached, which reduces signal noise.
Feet
The feet on the Slingshot are regular black-dyed PTFE (Teflon) feet with slightly rounded edges. Glide is decent and thickness average.
