Packaging

Much like the Rival 3, the Rival 3 Wireless resides in a remarkably small box. Inside, one finds the mouse, a quick start guide, and two AAA-batteries (Duracell OEM).

Speaking of which, the Rival 3 Wireless can be operated with one or two AAA-batteries. When using only a single AAA-battery, battery life will be less than 50% of the full configuration. As described in the included leaflet, the battery cover needs to be disengaged by pulling down. Any other method will not work.

Weight

As mentioned above, the Rival 3 Wireless can be operated with one or two AAA-batteries. Without any batteries installed, my scale shows around 85 g (+/- 1 g). With a single AAA-battery installed, weight goes up to 96 g. Finally, with two AAA-batteries, the Rival 3 Wireless weighs in at 107 g. Although the two-battery configuration offers considerably better battery life, I much preferred running the Rival 3 Wireless with just a single AAA-battery. At 107 g, the Rival 3 Wireless does feel heavy, but not as much so at 96 g, which is only roughly 5 g more than what the old Rival 100 weighed. In its single-battery configuration, the battery will be slightly off-centered either to the left or the right, but I wasn't bothered much if at all by the resulting shift in weight balance. There is some potential to further save weight by using Lithium AAA-batteries instead of the regular ones.

Feet

The feet on the Rival 3 Wireless are standard black-dyed PTFE (Teflon) feet. They are of average thickness and glide decently well. Small indentations next to these make them easy to remove.
