Packaging

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

Weight

My scale shows around 79 g (+/- 1 g), which is exactly in line with the weight cited by Dream Machines. A very good weight for a wireless mouse of this size. The DM6 Holey Duo weighs 10 g more than the wired Holey S.

Cable

The DM6 Holey Duo comes with a braided charging cable (USB Type-A to Type-C). In terms of flexibility, it's not quite on the same level as the charging cables on the SteelSeries Aerox 3 Wireless, ASUS ROG Keris Wireless, or Glorious Model O Wireless, but no doubt ahead of the Razer DeathAdder V2 Pro. I'd say it's slightly worse than the regular shoelace cable on the wired DM6 Holey S. There is no anchor on the mouse-end of the cable, so the cable may come loose during play. Its measured length is 2 m, which is 20 cm more than what Dream Machines claims.

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 DM6 Holey Duo as short as possible. Since the mouse itself lacks a storage compartment for the dongle, the extender could also simply be used as something to attach the dongle to, which reduces the likelihood of the dongle being lost when traveling.

Feet

The feet on the DM6 Holey Duo are regular black-dyed PTFE (Teflon) feet. Glide is decent, and their size and shape is reminiscent of but not identical to Microsoft IME 3.0 feet. A set of replacement feet is included in the box as well, which is a very welcome addition.
