ENDGAME GEAR OP1w 4k Wireless Gaming Mouse Black – 4000Hz Polling Rate, Gamer Mouse Wireless | Kailh GX Switches | PixArt PAW3395 Optical Mouse Sensor

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 I would instantly buy a newer version of this mouse if they came out with one under 50g.Objectively this is one of the best mice on the market.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.

Amazing mouse! I have the OP1 8K and it's amazing, but I've never liked wired mouses. This mouse is essentially the same thing, but 4k polling rate and obviously wireless. The shape and coating of this mouse is amazing. Been using it for about a week now. Using a glass mousepad and the stock stakes are good, but I might replace them with Corepads or Tiger Ice V2s.

Great mouse, if it fits your hand it's hard to beat. Great customization options also.

Best build quality of a mouse i have ever used，great shape for smaller hands. Only thing is the switch is kind of loud so it's recommend to buy the HNCHK switch from egg for replacement.

Are you kidding me?Out of the box and cannot even check for a firmware update. Been sitting 10 minutes. Sensitivity is turned ALL THE WAY UP, and the mouse pointer hardly moves any faster than medium sensitivity for a standard $10 mouse. The plastic feels like it should be in the rubbish bin.I was specifically looking for a highly sensitive gaming mouse and this is just terrible, actual junk.

I feel like the mouse is great, but the only problem is the shape despite this being a small mouse. It seems like the hump just doesn’t work great for palm claw unless your wrist is not on the mouse pad and riding hider higher on the mouse the clicks are great, but not better than Omron clicks And a real positive is how mod friendly the mouse is, which is also great unfortunately just doesn’t work out with my 18 cm x 8 cm hands for claw grip

Truly endgame. Amazing performance combined with great and simple driver software

Awesome mouse. I love that you can replace the switches without any soldering. Mouse is very balanced and feels lighter than other mice I have that actually weigh less.
