VT7 Max Gen-2

Rapoo vt7/vt9 max gen-2 (or nonmax if you are fine without coating black and white nonmax don't have it)) would be less than 45$ from shop.rapoo.com, also you can also look at mchose l7 ultra/ultra+ or atk mice, but rapoo would be the best price/performance

Not like options I suggested don't have 8k, they have, and has decent battery life even at 4-8k

Rapoo vt7 max (or other rapoo gen-2 stuff with nRF54L15 MCU) as well as rawm leviathan v4

Rapoo gen-2 stuff like rapoo vt3s Max gen-2 or vt7 max. 700+h at 1k polling

Rawm es21 pro (or ES21/ER21 if you need something cheaper), also rapoo vt7/vt3gen2/vt2gen and atk mice with 3395 sensor and better, scyrox v6/v8, zaopin

I just ordered a vt7 max gen 2 for $28 bucks on Rapoo's AliExpress storefront. It was the same price with the dock so I got it, but I can't imagine needing it since that battery life is actually insane.

The prices are crazy. I ordered a vt3 max in the middle of setting up my vt7 because I was so impressed. Vt2 is super tempting just for the value alone.

Try a Rapoo vt3 gen 2 while they are cheap! Maybe try one of their other shapes that look interesting while you're at it. Vt7 definitely has palm filling potential as well with its ergo-lite design.

I hated attack shark software I got a rapoo vt7 gen 2 mouse and it's been amazing

Attack shark and rapoo were same price where I'm from I even paid less for rapoo and the mouse has way more tuning option

Rapoo VT7 Max. I just picked one up, loving it so far. Have almost the same measurements as you (19x10) and the VT7 Max has been fantastic.

Rapoo vt7max is an amazing low budget, high quality mouse that I've been using for about a month with zero complaints. The scroll wheel button feels cheap when it clicks but everything else is 10/10 so far.
