Packaging

Aside from the mouse, one finds two Omron 5-pin optical switches (D2FP-FN), a charging cable (USB Type-A to USB Type-C), wireless extender, set of replacement mouse feet, tweezers, quick start guide, warranty guide, and stickers in the box.

Weight

My scale shows around 89 g (+/- 1 g), which is exactly in line with the weight cited by ASUS. The Gladius III Wireless is a large mouse, so achieving this weight without resorting to externally visible holes is commendable. For comparison, the similarly sized Razer DeathAdder V2 Pro weighs in at 87 g. Moreover, the wired Gladius III weighed in at 76 g, so the added weight is pretty much entirely due to the added battery.

Cable

The Gladius III Wireless comes with a paracord-like, braided charging cable (USB Type-A to USB Type-C). It's very similar to the charging cable of the ASUS ROG Keris Wireless and just as soft and flexible. Accordingly, I had no issue whatsoever using the Gladius III Wireless as if it were a wired mouse. That having been said, there is no anchor on the mouse-end of the cable, so the cable may come loose inadvertently during use. The charging cable also functions as an extension cable if used in conjunction with the wireless extender, which may be used to keep the distance between the dongle and Gladius III Wireless as short as possible. The cable has a measured length of 2 m.

Feet

The feet on the Gladius III Wireless are pure PTFE (Teflon) feet with slightly rounded edges. Glide is very good. The ring around the sensor ensures CPI stays consistent upon applying vertical pressure. ASUS includes a set of replacement feet in the box, which is always very handy.
