Packaging
Aside from the mouse, one finds a braided charging cable (USB Type-A to Type-C), wireless dongle, wireless extender, box containing three sets of replacement switches (Huano Brown Silent, Omron D2FC-F-7N (20M) (OF), TTC Gold), set of grip tape, set of replacement feet (full set of glass feet, five PTFE top skates), set of button spacers, PH00 screwdriver, tweezers, replacement CPI button cover, and quick start guide inside the box.
Weight
My scale shows around 61 g (+/- 1 g), which is slightly more than the weight cited by Incott. For comparison, the similarly sized and likewise solid-shell VGN Dragonfly F1 Pro Max weighs 55 g, whereas the similarly sized and too solid-shell Endgame Gear OP1we weighs 58 g, though neither of them feature hot-swappable main button switches. An excellent weight.
Cable
The HPC01M Pro comes with a paracord-like, braided charging cable (USB Type-A to Type-C). In terms of flexibility, the cable is slightly below average, to where playing while charging may feel restrictive. 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.
Feet
The feet on the HPC01M Pro are non-dyed pure PTFE (Teflon) feet. They are of above average thickness and have slightly rounded edges. Glide is very good. That said, the boxy design of the hot-swap skates in particular may be detrimental to the quality of glide. The ring around the sensor ensures CPI stays consistent upon applying vertical pressure. Several sets of replacement feet (full set of glass feet, five PTFE top skates) are included in the box.
4K Wireless Dongle
As a separate purchase, Incott offers the 4K Wireless Dongle, which as of this review is only compatible with the HPC01M Pro. After pairing the 4K Wireless Dongle with the HPC01M Pro, polling rates of 2000 and 4000 Hz will become available. Pairing is possible through the software by opening the settings dialog and selecting the pairing tool there. However, only one dongle can ever be paired to the mouse, so after pairing the HPC01M Pro to the 4K Wireless Dongle, the included dongle will no longer work, and vice versa. In addition to the 4K Wireless Dongle, the box also contains a full set of replacement feet.
