ENDGAME GEAROP1 Gaming Mouse - Precision Sensor, Kailh GX Switches, Lightweight Design, Swappable Buttons, Hybrid Skates, White

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.

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.

honestly, best mouse i have ever used. The performance is un matched. build quality is amazing. scroll wheel feels great; clicks are insanely responsive. Sensor is extremely accurate and u never run out of battery! cable honestly never bothers me even when gaming in fps titles

I would like to preface this review that I'm coming from a G203 that I used to daily drive and needed a replacement due to the scrollerwheel encoder going bad and replacing it 3 times and the side buttons double clicking constantly. The ENDGAME GEAR OP1 does not have these issues after almost a month of usage, but I will edit this review when it does happen.I needed a replacement for my G203 mouse, and this one is the best I found. The software is pretty nice and doesn't interact or break the ENDGAME software with Logitech's. So if you have 3 Logitech mouse products like me that aren't the G203, you're good to go.It's wired, feels nice in my hand, and has the right amount of buttons I need. The specs are good, and the DPI is very close to the G203, so it doesn't affect my aim or daily use. It's also easy to maintain and open for cleaning inside.However, I noticed a couple of things. I have to clean this mouse much more often. After just one day of use, the texture goes from clean and smooth to rough and dirty, much more than the G203.Also, the USB cable is shorter than the G203's. Usually, this wouldn't be a big issue because most people have their computers next to them in a gaming setup. But my computer is in the living room, so I had to move my monitor and mousepad closer to the edge of the desk to have enough space for gaming comfortably.Overall, if you don't mind the cons and need a replacement, the ENDGAME GEAR OP1 is pretty much the best bang for your buck. It has everything the G203 has, plus it feels easier to maintain. It feels really nice in the hand if you are used to the G203's shape.
