Packaging

Aside from the mouse, one finds a manual, several stickers, and a Lithium AA-battery (Energizer Ultimate) in the box.

Weight

As the Orochi V2 can be operated with either a single AA or AAA-battery, albeit not both at the same time, the weight changes accordingly. Without any battery inserted, my scale shows around 58 g (+/- 1 g). With an Alkaline AAA-battery (not included), the weight goes up to 68 g, while the included Lithium AA-battery brings the weight up to 73 g. For comparison, the SteelSeries Rival 3 Wireless with a single Alkaline AAA-battery installed weighs in at 96 g, although one has to keep in mind that it is quite a bit bigger. Likewise, though not officially supported, the Logitech G305 too can be operated with an AAA-battery, and weighs around 83 g in that case, though this one is also quite a bit bigger than the Orochi V2. Nonetheless, the Orochi V2 is easily the lightest proper battery-driven wireless gaming mouse thus far. Furthermore, the fact that the AA-battery slot is mass-centralized deserves to be mentioned as well.

As the Orochi V2 lacks a wireless extender, the wireless dongle needs to be plugged directly into a USB port. When doing so, as per Intel's documentation, it is strongly recommended not to use a USB 3.x port, as ports of this type may introduce interference adversely affecting wireless operation. A storage compartment for the wireless dongle is located right next to the battery slots.

Feet

The feet on the Orochi V2 are 100% pure PTFE (Teflon) feet. They are of above average thickness and glide very well. The ring around the sensor ensures CPI stays consistent upon applying vertical pressure.
