Packaging

Aside from the mouse, one finds a USB Type-A to Type-C cable, wireless dongle, wireless extender, set of replacement feet, and a quick start guide inside the box.

Weight

My scale shows around 54 g (±1 g), which is slightly less than the 55 g cited by be quiet!. For comparison, the larger and solid-shell Teevolution Terra Pro weighs 51 g. A very good weight overall.

Cable

The Dark Perk Ergo comes with a braided charging cable (USB Type-A to Type-C). In terms of flexibility, this one is slightly above average, allowing playing while charging without feeling overly restricted. Its measured length is 1.75 m.

The charging cable also functions as an extension cable if used in conjunction with the wireless extender. The wireless extender can be used to keep the distance between dongle and mouse as short as possible. A storage compartment for the dongle is found on the underside of the mouse, which includes a compartment door.

Feet

The feet on the Dark Perk Ergo are white-dyed pure PTFE (Teflon) feet. They are of average thickness and have slightly rounded edges. Glide is very good. The ring around the sensor ensures CPI stay consistent upon applying vertical pressure. A set of replacement feet is found in the box.
