ENDGAME GEAR OP1 Gaming Mouse - Precision Sensor, Kailh GX Switches, Lightweight Design, Swappable Buttons, Hybrid Skates, Black

Hand size: 17.5 x 9Main Grip Style: ClawMod: Lighter Kailh Switches ($10)I’ve spent about about two hours a/b testing this mouse against my Lamzu Atlantis mini and here are some of my thoughts.Build - No competition here, the op1we wins by a long shot. As many reviews mentioning its premium build, and even in person I’m shocked at how well constructed and strong the shell is. I also appreciate that it’s a fully closed design with no holes at all. Having the Atlantis mini for about 6 months now, I’ve noticed that dust tends to accumulate within the mouse and it needs dusting from time to time.Clicks - Everyone has mentioned this and it’s true, the stock switches are on the heavier side. I’m sure with time I could have gotten used to it for valorant but I prefer lighter clicks so I can more easily tap and burst fire. For this reason I bought the $10 lighter switch pack and installed it almost immediately. Install was a breeze. After removing the two bottom screws the top and bottom half separate quite easily, and I didn’t require any other prying tools to open it. I noticed slight pre travel on the lighter clicks and almost no post travel. The Atlantis mini has huano shell pink dots and they have slightly more pre travel and slightly more post travel. I was able to get used to this slight difference within the first hour of use. The lighter clicks on the op1we are just as spammable and light as the Atlantis clicks, but it does suck that this is a separate cost/addition.Coating - I have the white op1we and the black Atlantis mini. It’s clear that the coating on the op1we is the winner in this category as well. In the first minute or so the op1we coating may feel slippery but once your hand heats up a bit the mice holds well. The Atlantis mini has a chalky coating that is hardly serviceable and I personally needed to put pulsar supergrips on it to keep it locked in. For the op1we I ended up putting supergrips on the right and left side of the mouse where my thumb, ring, and pinky fingers make contact, but it was completely optional and not a requirement.Shape/Comfort - This category is largely preference based with some caveats. The op1we is a great shape for claw, relax claw and fingertip. I use a variety of each style depending if I’m gaming (claw) or just surfing the web (relaxed claw or fingertip). Between the op1we and Atlantis mini, the op1we will be a better shape for fingertip given its flatter sides. But for claw it’s largely preference. If you prefer the mouse to fill out your hand then you may like the Atlantis mini. Alternatively if you prefer having less hand contact then the op1we may be a better fit. One thing to consider is that since the op1we is a bit longer in the hand than the Atlantis mini, I feel like side to side maneuverability (e.g. range of motion while tracking a horizontal target left and right) takes a small hit. However this didn’t affect me in game while testing in valorant at all.Weight - Techncially, the winner here is the Atlantis mini. The op1we is 58.5 grams while the Atlantis mini is approximately 49 grams. The difference in weight is noticeable but not a deal breaker. I associate the additional weight with better build quality and no holes. In game, I forgot about the weight difference completely and was able to dial in.Size: For my hand size this mouse is basically a perfect fit in terms of dimensions. So if you’re also around 17.5 x 9 and have used smaller mice before, this will be no surprise.Feet: I can’t make a direct comparison between the stock feet because my Atlantis mini is using tiger ice dot skates, but the op1we stock skates are quite smooth and micro adjusting on my LGG Venus mousepad was no issue. Won’t need to swap these out any time soon.In summary, this is a great mouse, even at the $110 price I purchased it at ($100 + $10 switch pack). I had no issues with the 3370 implementation, the shape is versatile for many grip styles besides palm, and the coating is good enough to use without grips. I give the op1we a strong recommendation.

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.

Splendid mouse, my only complaint is that the coating on the right side of the mouse gets smudged!

God tier mouse, fastest clicks, pretty light, fit like a glove, only downside for me is the cable but if ignored its the endgame for mouse. Internals are great, shape is great, cable assist on the mouse is nice but a cable mouse is still a cable mouse. Weight is nice if lower would be amazing. V2 of it coming out soon

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.
