Packaging
On the AX, the minimalist approach extends not only to the aesthetics: Aside from the well-cushioned mouse, nothing else is found in the black and white box. This is part of VAXEE's commitment to sustainability, producing as little waste as possible.
Weight
My scale shows around 81 g (+/- 1 g), which is slightly more than the weight cited by VAXEE. Compared to the Zowie EC2-B, the AX is roughly 10 g lighter. Though no doubt not ultra-lightweight, the AX isn't heavy either, and more importantly, shell rigidity has been improved over the NP-01.
Cable
The AX features a paracord-like, braided cable. It's a bit stiffer than most other paracord-like cables—I'd rank it similarly to the Razer Viper Mini cable. VAXEE cites durability as the reason for choosing this cable over more flexible ones. Its measured length is 2.10 m. The cable has an attached ferrite bead, which reduces signal noise, as well as a gold-plated USB connector. Much like on the NP-01, the cable exit is angled upwards slightly.
Feet
The feet on the AX are white-dyed pure PTFE (Teflon) feet. Glide is perfectly fine. Their size and shape is indeed identical with those of the NP-01, though this time around, the stock feet are 0.6 mm (measured). The 0.45 (0.4) mm feet on the NP-01 proved slightly too thin, so I'm pleased to see VAXEE going with the thicker feet right from the get-go. Small indentations next to the feet make them easy to remove.
