Packaging

Aside from the mouse, one finds a USB Type-A to Type-C charging cable, wireless dongle, wireless extender, quick start guide, sticker, and several information leaflets in the box.

Weight

My scale shows around 71 g (+/- 1 g), which is slightly more than the weight cited by Glorious. The Model O 2 Wireless also weighs marginally more than its predecessor, the Model O Wireless, and quite a bit more than the similarly sized and solid-shell Razer Viper V2 Pro at 58 g or Endgame Gear XM2we at 61 g, though these do not feature RGB lighting. A good weight overall.

Cable

The Model O 2 Wireless comes with a paracord-like, braided charging cable (USB Type-A to Type-C). An anchor at the mouse-end of the cable ensures the cable not coming loose during use, although it also prevents one from plugging in the connector in either orientation. In terms of flexibility, this one is roughly on par with the regular "Ascended" cable on the latest Glorious wired mice. Accordingly, the Model O 2 Wireless can be used as if it were a wired mouse with barely if any perceivable difference in terms of handling. Its measured length is 1.95 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.

Feet

The feet on the Model O 2 Wireless are white-dyed pure PTFE (Teflon) feet with slightly rounded edges. Glide is very good and thickness above average. Their size and shape is identical to that of the Model O Wireless.
