Packaging
Aside from the mouse, one finds a USB Type-A to Type-C charging cable, wireless dongle, two sets of replacement feet (fitted and dots), set of grip tape, and quick start guide in the box.
Weight
My scale shows around 53 g (+/- 1 g), which is exactly in line with the weight cited by Fantech. For comparison, the original Aria XD7 weighed 60 g, whereas the smaller Zaopin Z1 weighs 52 g. A very good weight.
Cable
The Aria II Pro comes with a paracord-like, braided charging cable (USB Type-A to Type-C). In terms of flexibility, this one ranks below the charging cable of the Aria II, and can only be described as stiff. Accordingly, playing while charging is not possible without feeling restricted. Its measured length is 1.80 m.
Feet
The feet on the Aria II Pro are non-dyed pure PTFE (Teflon) feet with slightly rounded edges. Glide is excellent and thickness average. The ring around the sensor ensures CPI stays consistent upon applying vertical pressure. Two sets of replacement feet (fitted and dots) are found in the box.
