Packaging
Aside from the mouse, one finds a braided charging cable (USB Type-A to Type-C), wireless dongle, wireless extender, set of grip tape, set of replacement feet, and quick start guide inside the box.
Weight
My scale shows around 57 g (+/- 1 g), which is slightly more than the weight cited by Waizowl. For comparison, the similarly sized and solid-shell Razer Viper V2 Pro weighs marginally more at 58 g, and the likewise similarly-sized and solid-shell Endgame Gear XM2we also weighs more at 61 g. An excellent weight.
Cable
The OGM Cloud comes with a paracord-like, braided charging cable (USB Type-A to Type-C). In terms of flexibility, the cable is strictly average, though playing while charging is still possible without feeling too restricted. The measured length of the cable is 1.80 m.
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.
Feet
The feet on the OGM Cloud are pure PTFE (Teflon) feet with little to no dye added. They are of above average thickness, and glide is excellent. The ring around the sensor ensures CPI stays consistent upon applying vertical pressure. Since the recesses for the feet are larger than the feet themselves, skates of most sizes and shapes can be used on the OGM Cloud. A set of replacement feet is found in the box.
4K Wireless Dongle
As a separate purchase, Waizowl offers the 4K Wireless Dongle, which as of this review is compatible with the OGM Pro and OGM Cloud. After pairing the 4K Wireless Dongle with the OGM Cloud, polling rates of 2000 and 4000 Hz will become available. Pairing is possible by holding the left and right main buttons along with the scroll wheel pressed for several seconds, while the mouse is turned on and the 4K dongle plugged in. However, only one dongle at a time can be paired to the mouse, so after pairing the OGM Cloud to the 4K Wireless Dongle, the default dongle will no longer work, and vice versa. A dedicated extension cable is included with the 4K dongle, which measures 1.45 m.
