Corsair Sabre V2 Pro
$51 under your budget
Across 9 sources nothing wireless under $100 is lighter: 36 g, native 8,000 Hz polling and a 33,000 DPI Marksman S sensor, with no dongle to buy.
Fit ledger — need → measured evidence
■ The catch — co-equal billing, always
Run it at 8,000 Hz and it lasts 16 hours. Corsair rates 70 hours at 1,000 Hz but only 16 at 8K, so using the headline feature means charging daily. And at $99.00 — up 41% from $69.99 since the June check — it sits $1 under this category's $100 line with zero headroom: one increase and it breaks the promise in the URL. It also has only 5 buttons.
Dealbreaker? Keychron M3 Mini V2 8K: same native 8K, $69.99, 140-hr battery ↓

Traps — this verdict avoids
Why the Corsair Sabre V2 Pro is right for you
It avoids every trap below — and for just me, under $150, 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.
