Packaging
Aside from the mouse, one finds a USB Type-A to Type-C charging cable, wireless extender, wireless dongle, set of grip tape, and quick start guide in the box.
Weight
My scale shows around 55 g (+/- 1 g), which is almost exactly in line with the weight cited by MCHOSE. For comparison, the smaller Finalmouse Starlight (Small/Achilles) weighs 46 g, while the similarly sized LAMZU Maya weighs 47 g, though both of these come with a smaller battery. An excellent weight.
Cable
The AX5 Pro Max comes with a paracord-like, braided charging cable (USB Type-A to Type-C). In terms of flexibility, this one is below average, likely due to the added shielding necessary to ensure signal integrity at 8000 Hz in wired operation. Thus, playing while charging, or wired usage in general, may feel restrictive. Its measured length is 1.75 m, and a ferrite bead is attached.
The charging cable also functions as an extension cable if used in conjunction with the wireless extender, which can be used to keep the distance between dongle and mouse as short as possible. A storage compartment for the dongle is found under the rear skate.
Feet
The feet on the AX5 Pro Max are regular black-dyed PTFE (Teflon) feet. They are of average thickness and have slightly rounded edges. Glide is decent. The ring around the sensor ensures CPI stays consistent upon applying vertical pressure.
