Razer Viper V3 HyperSpeed
$35 under your budget
Best all-round value under $100 — 9 sources converge on it: a Focus Pro 30K sensor, an ambidextrous 127 mm shell for claw and fingertip grips, 280 hours per AA.
Fit ledger — need → measured evidence
■ The catch — co-equal billing, always
It ships at 1,000 Hz, not 8,000. Razer's HyperSpeed wireless mice advertise 8K polling but only reach it with the HyperPolling dongle — a separate ~$30 purchase that turns a $44.99 mouse into a ~$75 one. The AA that buys the 280-hour battery also adds 23 g you cannot remove.
Dealbreaker? Wired DeathAdder V3 does native 8K for $32.99 ↓

Traps — this verdict avoids
Why the Razer Viper V3 HyperSpeed is right for you
It avoids every trap below — and for just me, under $80, it is the pick because it delivers:
The 8K you have to buy twice
Razer's HyperSpeed wireless mice advertise 8,000 Hz but ship at 1,000 Hz — the HyperPolling dongle is a separate ~$30 purchase. The Keychron M3 Mini V2 8K, Corsair Sabre V2 Pro, Endgame Gear OP1 8K v2 and wired DeathAdder V3 do 8K natively with nothing extra to buy.
DPI theatre
Every pick here except the G203 and wired Cobra carries a flagship sensor, and the gap between 18,000 and 33,000 DPI is nil at the 400–1,600 DPI most players actually use. Shape, weight, switch feel and connection are the only real variables under $100.
Weights that hide the cable
Quoted grams are not comparable. Corsair lists the Scimitar RGB Elite at 148.33 g including its 1.8 m cable while Engadget quotes 108 g for the body, and the Viper V3 is 59 g bare but 82 g once its AA is in.
