Packaging

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

Weight

My scale shows around 72 g (+/- 1 g), which is a decent bit higher than the weight cited by DELUX. For comparison, the larger and likewise hole-free Razer Viper Ultimate weighs slightly more at 74 g, whereas the Viper V2 Pro weighs significantly less at 58 g. A good weight overall.

Cable

The M800 Pro Highspeed comes with a paracord-like, braided charging cable (USB Type-A to Type-C). In terms of flexibility, this one is above average, soundly beating the charging cable of recent Razer mice, to where playing while charging is possible without feeling overly restricted. Its measured length is 1.55 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 can be found on the underside of the mouse, though there is no compartment door.

Feet

The feet on the M800 Pro Highspeed are regular black-dyed PTFE (Teflon) feet with slightly rounded edges. Glide is decent and thickness average. A set of replacement feet is included in the box.
