Ninjutso Sora V2 8K Review: The 40-Gram Small-Hand Special

Name: Ninjutso Sora V2 8K
Brand: Ninjutso

★★★★½ 4.5/5

Reviewed 2026-06-20

At 40.9 g the Sora V2 is one of the lightest real mice you can buy, and it pairs that with a small symmetrical shell built for claw and fingertip grips. The PAW3395 and 8K polling clear the floor comfortably — this is a shape-and-weight buy, and a sharp one.

Best for: Claw and fingertip aimers with small-to-medium hands who want the lightest credible mouse without going gimmicky.

The good

+40.9 g — among the lightest mice on the market that aren't a novelty
+Small 119.2 mm symmetrical shell tuned for claw and fingertip grips
+PAW3395 sensor and 8000 Hz polling; nothing to fault in tracking
+$99.99 for a genuine featherweight flagship

The catch

−Small and narrow — too little mouse for large hands or a palm grip
−Extreme lightness is preference and comfort, not a measured aim edge (PD013)
−Boutique availability and thinner aftermarket than the big brands
−Ultra-light shells feel fragile or hollow to some hands

AimBench insight

At 40.9 g on a narrow 59.8 mm body this is a claw/fingertip-only mouse — a palm gripper or anyone over ~18 cm hands will find nothing to anchor; if 40.9 g spooks you, the OP1 8K shares the small-shell brief at 49.5 g wired for a more planted feel.

The Ninjutso Sora V2 8K chases one number harder than almost anything else here: 40.9 g. That puts it within a few grams of the lightest mice ever shipped, and unlike some weight-record chasers it does it on a normal, solid-feeling symmetrical shell rather than a skeletonised gimmick. The PAW3395 sensor and native 8K polling round out a faultless input chain.

A small-hand, fingertip shape

The 119.2 x 59.8 x 37.7 mm shell is small and narrow, and that decides who should buy it. Claw and fingertip grippers with small-to-medium hands get a mouse that nearly vanishes; large hands and palm grippers will find nothing to hold. Match it to your hand honestly first — a great mouse on the wrong hand is the wrong mouse.

Where the grams stop mattering

Lighter feels faster, and for a fingertip player flicking all day the fatigue saving is real. But the accuracy benefit of weight saturates, and it can reverse if a mouse gets too light for your hand — the controlled evidence shows too-light hurts. Treat the 40.9 g as a feel feature you'll either love or find too insubstantial, not as a rank you can buy.

If 40.9 g sounds too light to trust, the OP1 8K (49.5 g, wired) gives you a similar small-shell feel with a touch more substance. Use the hand-size ranker to confirm a small shell suits you before chasing the weight record.

Logitech G PRO X2 Superstrike Review: The Click, Reinvented

The first genuinely new idea in gaming mice in years: inductive analog main switches you can tune like a Hall-effect keyboard — adjustable actuation, rapid trigger on the clicks, and a haptic 'feel' you dial in. It's a superb 61 g flagship; just know the edge is feel and consistency, not a win-rate you can measure.

The most-used mouse in pro Valorant and CS2 for a reason — a 54 g ambidextrous shape that disappears under fast aim. You pay the flagship price for refinement, not raw advantage.

The most universally-fitting shape in esports at 60 g. Not the lightest and not the cheapest, but the hardest mouse to dislike — and the easiest to recommend blind.

A wide, precise, near-reference open-back at a mid price — the strongest value pick for competitive positional audio. The one genuine audio edge, at the point where it saturates.
