Now also available: optional locked sensor frame rate at 20,500fps for even more responsive and precise tracking performance. Furthermore, for grip styles where the mouse is not held straight to the direction of movement, the "Sensor Angle Tuning" feature allows the tracking axis to be adjusted from -127 to +127 degrees in 1-degree increments, facilitating swift swipes and opponent tracking.

Kailh GX Switches developed by Endgame Gear

Designed for lightning-fast precision at all polling rates, the mechanical Kailh GX switches guarantee you won't miss a crucial click. Their SPDT configuration ensures optimal electrical contact and unmatched reliability. Featuring both top and bottom contacts, Kailh GX Switches excel whether you prefer low click latency in GX Speed Mode or security in GX Safe Mode. What sets them apart is their crisp, defined click sensation, offering tactile feedback for enhanced gaming control. Precise actuation and a balanced design ensure flawless, spam-friendly rapid-fire actions.

Industry-Leading Click Latency

The OP1w 4k v2 raises the bar for wireless performance, boasting click latency averaging below 310 microseconds*. With a steady 4000Hz polling rate for the clicks, you'll enjoy ultra-low click latency across all sensor polling rate options. GX Speed Mode further lowers click latency by about 1ms. This exceptional responsiveness guarantees instant registration of every click, empowering you in crucial gaming moments and helping secure those game-winning duels. We didn't stop there. We've optimized motion latency to an average of under 400 microseconds**, ensuring unmatched responsiveness. Initial motion latency from a standstill remains consistently fast across all polling rate options, reinforcing your gaming advantage.

Redesigned Shape for Versatile Claw Grip

The OP1w 4k v2 gaming mouse offers unparalleled comfort during those intense gaming sessions, allowing you to focus on your own performance. Drawing inspiration from the popular XM shape, the OP1 takes it up a notch while keeping an emphasis on claw grips. Its flatter sides provide ultimate flexibility for finger placement, making it an excellent fit even for gamers with larger hands. The extended side walls prevent accidental clicks, allowing you to rest your fingers on the edge without any interruptions. This subtle yet significant design change offers additional comfort and control, catering to gamers with various hand sizes and grip styles.

Swappable Main Button Switches with Optional Switch Packs

What makes a mouse click great? Ask this question to 10 people and get 11 different answers. Everyone has their own preferences and sometimes we just want to use what nobody else is using. While the Kailh GX is a switch with a very good combination of short internal travel, crisp actuation point and spammability, you may still want to try your favourite switch. All OP1 mice have a swappable main button switch design with accessible screws at the bottom plate. This allows for effortless customization, giving you the perfect click feel tailored to your liking. Choose from a variety of switch packs offering different click sensations, and follow our simple step-by-step guide to replace the switches. With the universal switch pack, you can use any mechanical switch you can find, solder-free.

Prioritizing Performance

We've engineered our wireless technology to prioritize performance over anything else. By running the sensor in permanent Corded Mode and minimal power-saving on the NordicCloseThe Nordic countries are generally considered to refer to Denmark, Finland, Iceland, Norway and Sweden, including their associated territories. 58240 MCU, we ensure unrivaled responsiveness for your gaming experience. To balance the demands of high performance and extended battery life, by default the sensor switches to power-saving mode after 1 minute of inactivity, transitioning into Deep Sleep mode after 3 minutes. Users can easily customize these settings to tailor their gaming preferences and also disabling Power Saving and Deep Sleep altogether. With the default settings, the OP1w 4k v2 delivers approximately 30 hours of battery life for continuous gaming at a 4000Hz polling rate, empowering gamers with uninterrupted playtime at peak performance.

Hybrid Skate Design

Similar to the click feeling preference, how a gaming mouse should glide is a science on its own and arguable also depends on the genre of games you play the most. OP1 comes with our so called Hybrid Skate Design. That means out of the box, we chose a smaller skate set that offers a great balance between surface area, weight and glide properties. Additionally, we add a larger skate set and a sensor skate to the packaging, which is beneficial especially for softer mousepads. If you want to minimize the surface area of your mouse skates, say for use on a glass pad, the large skate grooves of the OP1 give you plenty of possibilities to place your favourite dot skates. The screws in the bottom plate can be accessed to open the mouse and change the main button switches without removing the skates. Thanks to an improved adhesive of the v2 models, removing your skates is now quick and clean, every time.
