Incredible build quality. The GX switches on the main clicks are crisp. Side clicks feel great and are in the perfect spot. The scroll wheel being so close the front is ideal (It’s one of the most underrated aspects of all the EGG mice).
I have 19x10cm hands and I find this mouse to be very comfortable. There's a couple different ways to grip it, but I tend to use a claw-style grip. The coating on the mouse helps with grip and feels nice. The grip can be enhanced with some small patches of grip tape in the right places.
Even at 1000Hz, the mouse is super responsive. This causes battery life to be so-so, regardless of the polling rate. I think you can feel the difference between 1kHz and 4kHz when using a 360Hz OLED. I couldn’t feel much difference on a 144Hz monitor though.
The software is pretty good. It does exactly what it needs to and nothing more. It doesn’t require an internet connection (besides downloading it) or an account.
It’d be great if they could make this mouse lighter. 58g makes it feel pretty dense compared to newer sub-40g mice, but it’s still pretty light. I would instantly buy a newer version of this mouse if they came out with one under 50g.
Objectively this is one of the best mice on the market. I think it’s subjectively one of the best mice as well.

★★★★★Insane hot swappable switch mouse!
I’ve gone through a lot of mice trying to find “the one.” I started with the Superlight v1 and v2 but my hand always felt fatigued. Then I tried the Sora v2 and realized shape really is king- it fit my claw grip perfectly but it was a bit too light and the tech wasn't super up to date. I moved to the Lamzu Atlantis Mini 4K, which I thought would be my long term main, but the back hump felt steeper than I liked and it could be inconsistent.
I got the OP1w v2 and it completely blew all of them out of the water.
It has the same overall feel as the Sora v2 in terms of shape and ergonomics, but with the added control from its slightly heavier weight and better tech. The updated sensor, MCU, higher tracking speed, and the option for hot swappable switches are huge.
Small warning: the “hot swappable” part is worded weird... you need to buy the Universal Switch Pack (available thru EGG) to actually get the swappable PCBs. The stock custom Kailh GX switches feel great though, especially with Speed Mode turned on in the EGG tool. I tried Huano Pink Dots (felt mushy and hurt my accuracy) and Kailh 9.0s (pretty good), but I might end up going back to GX tbh.
For reference, my hand size is 18 x 8 cm with a 7.9 cm middle finger and I use a claw grip. If you don’t claw, this mouse might feel weird since it kind of naturally puts your hand into a claw shape but in a comfortable way if that’s already your style. If you actually want to learn claw grip, this mouse might help too.
Overall, this mouse is wild. Not sure what could top it besides future tech upgrades.

★★★★★Spent hundreds on different mice and finally found one I like
One thing they can definitely improve is the haptic quality of the forward and back buttons. It makes the mouse feel artificially cheap since it's so light and the 90s mouse click sound isn't great. Make it feel like the best for a couple bucks more.
The hardware is amazing though. 6/5 optics 6/5 response rate anecdotal quality. I got it with desk sized mouse pad and it feels like when Morty felt True Level

★★★★★Double Click sensor broken.
The mouse double clicks on single click and there is even a software option to prevent this. However, even with the option turned on to its HIGHEST setting, this does not prevent the problem.
Someone mentioned opening the mouse and adjusting the button click tension. I don't know why I have to do that to get the mouse to work properly.
If you like fiddling with mice this is probably the mouse for you. If you would rather it just work this might be too much work for it to be worth it.

★★★★★A True Endgame
The Endgame OP1 shape is one of the strongest in the market and is now my favorite all time next to the Logitech 703, Logitech Superlight, and Razer's DeathAdder V3 Hyperspeed. I would describe the shape as a thinner middle ground between the Pulsar X2 and X2H. I understand the OP1 has been out for some time now but the hype is still real folks.
With absolutely zero creaking, my OP1w4K has one of the sturdiest build qualities I've felt, alongside my Vaxee Outset AX and aforementioned DeathAdder V3H. Both left and right clicks feel pleasant and snappy, and so do both thumb buttons. The sensor feels very accurate and responsive as well.
Running 2000hz polling rate with MotionSync has been my sweet spot, and I would estimate that there's around 35 hours of battery life with these settings. I want to note that my OP1w4K can't run MotionSync simultaneously with Deep Sleep as it would brick the mouse when waking up from Deep Sleep. Endgame's customer support on Discord advised that this was a known issue and to turn off either setting, which has done the trick. That said, there needs to be a future firmware update to fix this bug.
Also wanted to note my initial order received came in an unsealed product box and the OP1w4K inside was entirely used with its mouse feet/skates replaced with aftermarket dots. Whoever out there doing this to gaming mice on Amazon can go to elo hell.
Thankfully Amazon and/or Pro Gamersware USA quickly replaced my item the very next day. The new order received was sealed and the mouse inside was wrapped in plastic and completely brand new.
