[Designed specifically for gripping]
A completely new design that incorporates the philosophy of the previous XM shape, but is specialized for gripping. The sides are flat rather than inverted, allowing you to hold your fingers in any way you like without having to place your fingers in a fixed position. Additionally, the shell extends to the side of the main button, making it easy to place your finger on the right edge without worrying about accidentally clicking it.
[Fits all hand sizes]
Compared to the XM series, the height is almost the same, but it is smaller with a length of about 3.8 mm and a width of about 5.5 mm. Those with smaller hands will have a better fit, while those with larger hands will be able to hold it more comfortably.
[Co-developed mechanical switch "Kailh GX"]
Equipped with a mechanical switch "Kailh GX" jointly developed by Endgame Gear and Kailh, which has a unique internal structure and characteristics. Short, clear clicks and reliable feedback enhance game control.
[PixArt PAW3395 Sensor]
Equipped with the PixArt PAW3395 sensor, which provides unparalleled accuracy and ultra-fast tracking. With incredible performance of ~26,000 CPI, 650 IPS, and 50G, every mouse movement is precise and powerful. Furthermore, by utilizing the "Motion Sync" function, you can increase the sense of unity with hand movements and optimize gameplay. *The "Motion Sync" function supports polling rates up to 4000Hz.
[Paracord cable "Flex Cord 5.0"]
With the paracord cable "Flex Cord 5.0" and constant data connection with the PC, OP1 does not require power saving functions. There's no slight startup delay, and the mouse is always in a high-performance state, allowing you to execute every movement with unparalleled precision.
[Main switch can be customized]
Adopts a screw design that allows you to easily change the main switch. No soldering required, just remove the Phillips screw and pull out the switch to replace it. You can customize it to your own favorites from the various replacement switches (optional items) provided by Endgame Gear. *"OP1we Switch Pack" cannot be used with all OP1 wired models.
[Hybrid Skate Design]
Adopts a hybrid skate design that allows you to choose flexibly according to the mouse pad you use and your preferred sliding style. By default, a small skate with a good balance of area, weight, and glide is attached, and a large skate is also included for a soft mouse pad. The grooves for skates are wide, so you can freely decide where to paste dot type skates.
[Dry Grip Coating]
The seamless shell is coated with the same matte UV coating as the XM series, allowing you to operate the mouse with a high grip regardless of how wet your hands are.
[Customize with software]
Software is available that allows you to set each button, adjust debounce time, and set polling rate and LOD.
