Aside from the mouse, one finds a braided charging cable (USB Type-A to Type-C), wireless dongle, wireless extender, quick start guide, warranty card, set of grip tape, and set of replacement feet inside the box.
Weight
My scale shows around 55 g (+/- 1 g), which is exactly in line with the weight cited by VGN. For comparison, the similarly sized Pulsar X2 weighs marginally more at 56 g despite not having a full bottom plate and featuring a smaller battery, whereas the smaller G-Wolves Hati-S Plus 4K is lighter at 51 g, while also not having a full bottom plate, and likewise featuring a smaller battery. An excellent weight.
Cable
The Dragonfly F1 Pro Max comes with a paracord-like, braided charging cable (USB Type-A to Type-C). There is no anchor at the mouse-end of the cable, so the cable may come loose during use, although this is unlikely, given how tight it fits. In terms of flexibility, this is one is roughly on par with recent Razer charging cables, but not on the same level as ASUS ROG charging cables, for instance. Accordingly, charging while playing is possible on the Dragonfly F1 Pro Max without feeling overly restricted. The measured length of the cable is 1.80 m.
The charging cable also functions as an extension cable, if used in conjunction with the wireless extender. The wireless extender 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.
Feet
The feet on the Dragonfly F1 Pro Max are white-dyed pure PTFE (Teflon) feet. They are of average thickness and have slightly rounded edges. Glide is very good. The ring around the sensor ensures CPI stays consistent upon applying vertical pressure. A set of replacement feet is included in the box, albeit their size and shape is different from the stock feet.
Dragonfly F1 4K Smart Speed Wireless Dongle
The 4K wireless dongle arrives in a simple box only containing the dongle and a quick start guide, which is why the charging cable included with the Dragonfly F1 Pro Max ought to be used for connecting the dongle. Before the 4K wireless dongle can be used, pairing it with the mouse is required. In order to do so, one has to use a software called VGN Hub. On my system, the latest version (2.2.9) gave me an error message and did not work at all, but an earlier version (2.1.3) worked without issue.
Even though the software is entirely in Chinese, the pairing process is basically self-explanatory. After clicking the menu entry picturing a cog, an entry containing the words "4K, 2.4G" will be listed. After clicking this one, one needs to unplug the regular dongle, plug the 4K wireless dongle in, and make sure that the mouse is turned on. In the next step, the mouse should be placed right next to the 4K wireless dongle, and the left and right mouse buttons along with the scroll wheel click need to be pressed and held. At this point, the pairing process should be successfully completed. The mouse can only be paired to a single dongle at the same time. Hence, once the mouse has been paired with the 4K wireless dongle, it will stop working with the regular dongle, which would need to be re-paired to work again.
