Packaging
Aside from the mouse, a USB Type-A to Type-C cable, wireless dongle, set of replacement feet, and quick start guide are in the solid plastic box.
Weight
My scale shows around 68 g (+/- 1 g), which is slightly less than the weight cited by SPC Gear. The LIX Plus Wireless weighs exactly 9 g more than the wired LIX Plus, which is entirely due to the added battery. For comparison, the Glorious Model O Wireless is slightly larger and has no holes on the sides and buttons, and weighs 69 g. A very good weight overall.
Cable
The LIX Plus Wireless comes with a paracord-like, braided charging cable (Type-A to Type-C). In terms of flexibility, this one is quite average, roughly comparable with the charging cable of the Razer Viper V2 Pro. Its measured length is 1.60 m. The cable has a ferrite bead attached, which reduces signal noise.
As the LIX Plus Wireless lacks a wireless extender, the wireless dongle needs to be plugged directly into a USB port. When doing so, as per
Intel's documentation, it is strongly recommended not to use a USB 3.x port, as ports of this type may introduce interference adversely affecting wireless operation. A storage compartment for the wireless dongle is located on the underside of the mouse.
Feet
The feet on the LIX Plus Wireless are regular black-dyed PTFE (Teflon) feet. Glide is decent. The ring around the sensor ensures CPI stays consistent upon applying vertical pressure. A set of replacement mouse feet is included in the box.
