Packaging
Aside from the mouse, one finds a USB Type-A to Type-C charging cable, wireless extender, wireless dongle, two sets of replacement feet (fitted and dots), set of grip tape, and a 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 comes with a paracord-like, braided charging cable (USB Type-A to Type-C). In terms of flexibility, this one is slightly above average, and allows playing while charging without feeling overly restricted. Its measured length 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 Aria II are non-dyed pure PTFE (Teflon) feet with slightly rounded edges. Glide is excellent and thickness average. The ring around the sensor ensures CPI stay consistent upon applying vertical pressure. Two sets of replacement feet (fitted and dots) are found in the box.
