To achieve the best performance possible, OP1w 4k v2 is powered by the Nordic nRF52840 wireless MCU. The 4k dongle utilizes a Nordic nRF52820 to guarantee stable and reliable wireless data transmissions. Additionally, a Nuvoton M483 MCU is used in the dongle for the high-speed USB connection, enabling high wireless polling rates of up to 4000Hz for incredibly low sensor and click latency. The 4k dongle is included with the mouse for ideal performance straight out of the box.
Unlock ultimate precision and lightning-fast response with our custom PixArt PAW3950 U+1F95A sensor in the OP1w 4k v2. With up to 30,000 CPI max resolution, 750 IPS, and 50G acceleration, every movement is captured with raw accuracy and maximum impact.
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.*
* requires firmware 1.02 or above
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.

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.
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.
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 Nordic 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.

Well crafted and easy to assemble, decorative and useful piece.
Color: Bronze
This ring/jewelry holder is a little bigger than I expected it to be, and definitely is more suitable to a nightstand or dresser than on a bathroom vanity. That being said, the construction is very sturdy and it can easily hold a lot of jewelry. This is a great gift for a jewelry collector who already has a ton of jewelry and needs an innovative way to store and display it. There are a ton of branches on the tree, and each can easily fit 4-7 rings or necklaces.

Quick shipment, beautiful but slightly bent.
Color: Black
It's a beautiful piece, it was delivered sooner than expected which it is a plus the only thing I noticed after opening package, the top of the stand was slightly bent, I don't want to try to fix it because I'm afraid it may break. Overall it is very stable beautiful jewelry stand. Not too big and not too small. Perfect size.
