Packaging

Along with the mouse, one finds a quick start guide, warranty guide, and several stickers in the large box.

Weight

My scale shows around 102 g (+/- 1 g), which is largely in line with the 98 g (+/- 5%) cited by XPG. Being large and made out of PBT, the PRIMER is bound to be heavier than similar mice. Still, weight balance is good, so the mouse didn't feel heavy in use.

Cable

The PRIMER features a standard braided cable. Flexibility is very poor. It's one of those ultra-stiff braided cables which are irritating even when using a bungee. Its measured length is 1.80 m. The cable has a gold-plated USB connector.

Feet

The feet on the PRIMER are black-dyed PTFE (Teflon) feet. Glide is perfectly fine. Their shape and size is identical to IME 3.0 feet, which makes it very easy to acquire aftermarket feet if so desired.
