Packaging, Weight, Cable and Feet
Packaging
The incredibly compact box contains the mouse as well as a quick start guide.
Weight
My scale shows around 83 g (+/- 1 g) with a bit of cable. SteelSeries indicates 77 g without the cable, which seems a bit of a stretch. In any case, the Rival 3 is not a heavy mouse.
Cable
The Rival 3 features a regular rubber cable. Flexibility is above average—not great, but not bad either, it is roughly comparable to the Rival 310 cable. Its length is 1.80 m (measured).
Feet
The feet on the Rival 3 are standard black-dyed PTFE (Teflon) feet. They are of average thickness and glide decently well. Indentations next to each foot make them easy to remove.
