Packaging

Aside from the mouse, one finds a quick start guide and sticker in the box.

Weight

My scale shows around 57 g (+/- 1 g), which is almost exactly in line with the weight cited by Razer. For comparison, the larger and likewise hole-free Cooler Master MM310 wears 53 g. A very good weight.

Cable

The Cobra comes with a flexible, braided cable. In terms of flexibility, this one isn't much different from the cable used for the Viper Mini, albeit slightly more flexible when compared directly. Its measured length is 1.80 m.

Feet

The feet on the Cobra 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. Their size and shape is unchanged compared to the Viper Mini.
