ENDGAME GEAR OP1 8k Wired Gaming Mouse - 8000Hz Polling, PixArt PAW3395 Sensor, Kailh GX Switches, Black

I have exclusively used a Logitech G9x for the last ~14 years for mixed gaming and productivity. At this point I've repaired and replaced just about everything on that mouse - and many things several times over. If you've never seen/used one, just know that they have a very unique shape with no modern equivalent (low/short/wide). I have tried at least a dozen different mice over the years including the G305, G502, M65, Kain 200, etc, and while all have been good mice - none of them felt very comfortable or natural in my hand. I happened to come across the Endgame OP1 recently and despite being unfamiliar with the brand and the mouse having a rather uninspiring appearance, based on the specs I decided to give it a try (corded, non 8k, non RGB).I have been very pleased and impressed with this mouse, so much so that I bought another and am looking at other products from the company. The most outstanding trait for me is the OP1's ergonomics; while I've read it was designed for smaller hands, it feels really comfortable in my XL ones and preferred fingertip grip due to the shape of the sides and how it swells towards the back instead of getting narrower like so many others. Other significant positives: the side switches are well placed, the material is grippy and resistant to scratching, the skates are very well thought out, the shell is designed to be easily taken apart, the DPI etc is saved onto the mouse itself instead of requiring SW, there's plenty of room inside to add weights if needed, and the cord comes out at an angle which really helps to reduce the drag when moving.One quirk I noticed is while stock main switches (Kailh GX) are on the lighter side, the side switches are quite heavy. I suspect this is deliberate as you don't want the sides to get accidentally pressed, but the contrast gives the mouse a slightly mismatched feel at first. On the subject of switches, I also tried the OP1 hot swap switch kit with my preferred TTC Gold 60m but because TTC (and all other) switches have slightly different specs I found I would need to shim each one individually to make the clicks feel solid - went back to the stock ones for now, may revisit this later.If I had to pick something about the OP1 that I don't like, it would be the scroll wheel. The middle click travel is very short, it lacks tilt switches, the wheel is small and sits very low in the shell, the placement is a bit to far forward in a fingertip grip such that I find myself rubbing the plastic behind the wheel when scrolling, and while the encoder (TTC White/silver, 9mm) is a good one it's a bit smoother and lighter than I'd prefer. I also noticed that the mouse don't balance quite right; because the whole thing weights just 50g the cord makes it want to pivot under my hand in a light grip. I fixed this by adding a 8g weight to the rear of the mouse on the inside to counter the pull of the cord and now it balances perfectly. Do keep in mind these are extreme nitpicks from someone who's been using a G9x for the last ~14 years.Overall I'd give the OP1 a 9.5/10 and recommend it to anyone looking for a solid fingertip/claw mouse.

I was using a G305 before I bought this. The G305 was clunky, slow and uncomfortable to use over time, not to mention it caused massive fatigue. There was a huge skill gap that was unlocked just by switching to the op1 8k due to how much quicker it is than any mouse ive ever tried. On day 5 I am nearing controller levels of plays on warzone thanks to this thing. If you're latency sensitive and have small hands it does not get better than this. Its an instant buy for me if I had to buy a new mouse again. Pair this with a 14900KS, a unify x and a pcie to usb controller using real cpu pcie lanes and you have the best e sports latency gaming combo.

It’s such a great mouse even with the cord. Small, lightweight, great clicks all around. Had a minor issue with the first copy registering ghost clicks on the side button, but customer service was great and send me a new one. No issues since then. To be honest, I believe it may have been a firmware issue rather than hardware, but hard to say with certainty. If you want great performance, a small lightweight mouse, and don’t mind a cable, look no further. This one has stayed on my desk. I prefer having a small mouse for certain games, and a larger one. So it’s this guy and the Zowie U2 on my desk for the foreseeable future.

Avoid the black color as it picks up oils easily. The coating started to peel off after I removed grip tape.... never had that happen on any mouse before..My copy has an issue where sometimes my M1 would stay actuated after a click. I don't know what causes it and it doesn't happen often, but it's annoying when it does. Changing Kailh GX settings in the software didn't seem to do anything, neither did swapping the mouse switches for new ones.Good mouse otherwise

This mouse is absolutely amazing. I did a cable mod but even the stock cable has little resistance. This mouse is amazing for claw and fingertip grip and you can use it for palm if necessary. The performance of this mouse is insane at 8k polling. Highly recommend
