Packaging
Aside from the mouse, one finds a charging cable (Type-A to Type-C), wireless extender, wireless dongle, quick start guide, sticker, card with some words from Glorious' CEO, and a set of supplementary mouse feet inside the sturdy box.
Weight
My scale shows around 69 g (+/- 1 g), which is exactly in line with the weight cited by Glorious. Remarkably, the Model D Wireless weighs the same as the Model D despite being wireless. An excellent weight, especially when keeping the size of the Model D Wireless and fact that holes are only used sparingly for weight reduction in mind.
Cable
The Model D Wireless comes with a paracord-like, braided charging cable (USB Type-A to Type-C). An anchor at the mouse-end of the cable ensures the cable not coming loose during use. In terms of flexibility, this one is easily as good as the regular "Ascended" cable on the latest Glorious wired mice. Accordingly, the Model D Wireless can be used as if it were a wired mouse with barely if any perceivable difference in terms of handling. Its measured length is 2 m. The cable has a ferrite bead attached, which reduces signal noise, as well as a gold-plated USB connector.
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. Since the mouse itself lacks a storage compartment for the dongle, the extender can also simply be used as something to attach the dongle to, which reduces the likelihood of the dongle getting lost when traveling.
Feet
The feet on the Model D Wireless are white-dyed pure PTFE (Teflon) feet with slightly rounded edges. They are of above average thickness and glide very well. That said, I did experience some scratching of the bottom of the mouse on my copy. I'm actually not sure how, as when looking at the bottom, nothing sticks out that could be responsible for the scratchiness. Size and shape are identical to those of the regular Model D and D-. And much like on the latter, the footprint can be increased by adding the included supplementary feet, although I still struggle to see the point in doing so, as even when applied with utmost care, glide won't be perfectly even. The Endgame Gear XM1r solves this in a better way in my opinion.
