Introduction

Endgame Gear is a peripherals company based in Germany. Following the wireless OP1we, the OP1 8K is all about low latency. Equipped with PixArt's PAW3395 sensor capable of 26,000 CPI, the OP1 8K not only is capable of 8000 Hz polling, but also introduces a novelty in regard to its main button switches. Unlike regular mechanical switches, the GX switches developed by Kailh and Endgame Gear for the OP1 8K have both a top and bottom contact (SPDT, single-pole and double-throw). Hence, when actuating the switch, the click can already be registered when the top contact has been disengaged, instead of having to wait until the bottom contact is closed, reducing physical latency in the process. In addition, the GX switch can also be employed as a way of providing additional hardware debouncing, preventing unintended double-clicking. Weighing 49 g, the OP1 8K does without holes or an open-bottom design. The feet are made of pure PTFE, and the cable is the particularly flexible "Flex Cord 5.0." Configuration is possible within lightweight software that doesn't require installation. The OP1 8K is available in either black or white.

Packaging

Aside from the mouse, one finds a set of larger replacement mouse feet, set of grip tape, PH000 screwdriver, and a quick start guide in the box. The cable is routed around the mouse to prevent kinking.

Weight

My scale shows around 49 g (±1 g), which is slightly less than the weight cited by Endgame Gear. The direct competitors are the Razer Viper 8K, which is larger and likewise has a solid shell, and ends up weighing 69 g, as well as the HyperX Pulsefire Haste 2, which is also larger and has a solid shell, weighing 53 g. An excellent weight.
