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.
* tested with 10,000 clicks on XLAT v.1.4.0
** tested with 10,000 motion data points on XLAT v.1.4.0

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.

total complete junk.
Color: Black, Size: 1 Pack
STOP!!! Do NOT click on Buy. This is simply the biggest piece of **** you've ever seen. Impossible to put together because all the threaded inserts are misaligned. PLUS, it came busted. One of the arm rests was cracked all the way through. And a piss poor design, too. The back attaches to the armrests which in turn connect to the base. Without three or four people, it's simply not possible to put this worthless excuse for a chair together. And don't even THINK about using it WITH the back but WITHOUT the armrests!! Can't do it. Not possible. Terrible design. Seriously, this is right at the top of the list of useless junk I've gotten from Amazon. Not Amazon's fault exactly, they just sell the crap and at least they make it super easy to return this idiotic junk. OK, maybe it IS their fault. Shipped and sold by Amazon so there's that.... Oh, it took over a week to get here, too so there's THAT as well. Yup, looks like a great deal at first. But....after spending half your life trying to assemble it.... Nope. Not worth one damn cent. Utter absolute junk. Last warning: DO NOT BUY THIS RUBBISH!!! Don't you do it!! Clearly I loved this purchase.

extremely comfy
I’m in love with this chair. It’s extremely comfy and I can sit for long periods of time without any back pain. It’s easy to move around despite having no wheels. I have a plastic chair mat under my desk and it slides across it easily when I need to move it out of the way. I love the height of this chair as well. I am 4’11 and most chairs even at their lowest setting my feet don’t fully reach the floor comfortably. Usually my legs are leaned forward or on my toes a bit. However this chair at its lowest setting I can perfectly reach the floor and knees are at the comfiest 90 degree angle. SETUP: The chair was fairly easy to put together. Thankfully I read the reviews or I would’ve been extremely frustrated. The instructions for this are literally 4 steps that make it seem super easy. It is but not because of the instructions. Another reviewer left a video review and said it’s easier to put together if you swap steps 4 and 3 so you can line up the holes on the back with the bottom easier. This is 100% true so thanks for that reviewer!!! I’ll add on - you have to put the back and bottom together at kind of a weird angle to get the holes to line up and start with the back holes first! I can’t even really describe the angle but it feels really wrong. Almost like a wider angle than you think it should ever go. The back of the chair isn’t a 90 degree angle it tilts back a bit. If you can find the angle you’ll get the screws in with very little issue. I put this together by myself in about 5 minutes and 4 of those minutes were figuring out the angle for the back of the chair. CONS: I only have one con really. It’s the angle of the back of the chair. It’s tilted back just a tad too much for me. I like to be able to sit back in my chair and lean into the back but with this one if I do that I can’t type very well. I think if I add a lumbar support pillow I can lean back comfortably. To me, it’s not a huge deal because of the overall comfort and price of this chair. But something worth mentioning.

Im always cold wear robes over clothes no matter what robe I wear it gets fuzzy 🙃 lint roller works but its everyday thing

Can work, just need to be creative
Color: Black, Size: 1 Pack
The chair itself is comfortable and nice. Castor is very fluid as well as the hydraulic up-and-down. The problem is the screw sets for the back of the chair. The individuals that made this chair, and from what I see a majority of the other chairs like it, the bolt settings in the back of the chair are not angled correctly for the lumbar support angles. The intelligent, mathematicians, and engineers that have put this chair together did not calculate that lumbar angle. This means that when you try to put the bolt into the nut, you need to have at least a 25° angle for the bolt to fit properly in which the setting is not created for that process. In the end I ended up being able to get the bottom bolts into the backing of the chair, the top bolts were not able to get the proper angle to secure the chair. This being said, the chair still works comfortable and functional. It just does not have the top two bolts in the lumbar section.

Very good chair, comfortable and high quality.
Color: Black
I had my doubts, yet after a couple months I really love this chair. Its a very good quality. Comfortable and sturdy. It allows for me to lean back too, which is a big plus! It looks really great and I am glad I purchased this chair. If you are looking, then just buy it because it is as good as it looks in the pictures.
