Packaging, Weight, Cable and Feet

Packaging

Along with the mouse itself, one finds a wireless receiver extension cable, quick start guide, warranty guide, Logitech G product information booklet, and Logitech G sticker in the box. A single AA-battery (Duracell OEM) has also been included.

Weight

My scale shows around 114 g (+/- 1 g) without a battery installed. The provided AA-battery weighs 23 g, which brings the weight to around 137 g. Alternatively, an AAA-battery can be used with an adapter, which, depending on the chosen battery, may weigh around 15 g. A weight of 130+ g may seem like a lot, but considering the number of buttons, presence of a metal scroll wheel, and wireless functionality, the weight of the G604 is actually pretty decent. The wired Corsair Scimitar RGB Elite, for instance, already weighs 118 g, and the wired G502 comes in at 121 g, while the wireless G502 had to lose the metal scroll wheel to achieve 114 g.

Wireless receiver

The cable of the wireless receiver measures 1.5 m. The G604 comes with its own wireless dongle, which isn't compatible with any other Logitech wireless devices.

Feet

The feet on the G604 are standard black-dyed PTFE (Teflon) feet. Their glide is below average. The ring around the sensor ensures CPI stays consistent upon applying vertical pressure.
