Endgame Gear OP1w 4K v2 Review: The Small-Shell Wireless OP1

★★★★ 4.3/5

Reviewed 2026-06-26

The wireless, small-bodied sibling to the OP1 8K — 58.5 g, the flawless PAW3950 sensor, and a shape made for small-to-medium hands and fingertip grips. A strong #4 in the Premium class, with the honest caveat that nobody has published an isolated click-latency figure for this exact variant yet.

Best for: Small-to-medium hands and claw/fingertip aimers who want a wireless small shell and a sane price.

Product verdict — build, value & fit, not win-rate.

Weight58.5 g
SensorFlawless
Max polling4KHz

The good

  • +58.5 g wireless in a small, low 118 x 61 x 37 mm shell — rare for the small-shape crowd
  • +Flawless PAW3950 sensor (the v2 upgrade over the v1's PAW3395)
  • +Cuts the cord versus the wired OP1 8K while keeping the well-liked OP1 shape
  • +Premium price, not flagship — undercuts the marquee wireless mice

The catch

  • −Provisional measurement — no independent isolated click-latency lab figure for this exact variant yet
  • −4K wireless link, not native 8K (a non-issue in play, but it's behind the top flagships on paper)
  • −Small narrow shell is wrong for large hands or a full palm grip
  • −Premium-priced for what is, at heart, a small wireless mouse

AimBench insight

The '4K' in the name is the tell, not a downgrade: at this price Endgame Gear put the money into the PAW3950 and the shape rather than a native-8K radio you'd never feel — if you were going to run it at 1000-2000 Hz anyway (almost everyone should), nothing about the 4K cap costs you a thing.

Best-built score

Beyond the 5-star verdict above, we run every mouse through a measured best-built composite — independent click latency, sensor integrity, build/QC, weight, polling-link and value-for-money, each sourced (TechPowerUp et al.). It grades engineering compromise for the money, not win-rate. Here it scores 90/100, #4 of 11 in the Premium class — effectively tied with the picks above it (sub-perceptual gaps).

If you liked the OP1 shape but wanted it wireless, the Endgame Gear OP1w 4K v2 is the answer. It keeps the small, low 118 x 61 x 37 mm shell that claw and fingertip players with smaller hands gravitate to, drops the cable, and fits the flawless PAW3950 sensor the v2 revision introduced. At 58.5 g it's not chasing the featherweight record — it's chasing the right small shape, done wirelessly, at a Premium rather than flagship price.

Where it lands on the measured chart

It scores a strong fourth in the Premium class on our composite, behind the Maya X, Viper V3 Pro and Superlight 2. The reason it carries a 'measurement pending' badge is honest: no independent lab has published an isolated click-latency figure for this exact variant, so the model imputes it from the bracket and flags the uncertainty rather than passing off a vendor number as measured. Everything else — sensor, weight, link, build — is sourced and clean.

The shape decides it

This is a small mouse, and that's the whole point. Small-to-medium hands and claw/fingertip grips get a shell that vanishes; large palm hands will find nothing to hold. As always, the sensor and weight clear the competitive floor that a $60 mouse also clears — what you're paying the Premium price for here is a wireless small shape that's genuinely hard to find, not a measurable edge.

Cross-shopping small wireless shells? The Atlantis Mini goes lighter (49 g) but with a worse measured latency figure; the OP1w trades a couple of grams for a cleaner build. Confirm the fit on the mouse-by-hand-size ranker first.

Logitech G PRO X2 Superstrike Review: The Click, ReinventedThe 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.Razer Viper V3 Pro Review: The Pro-Tier Flick MouseThe 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.Logitech G Pro X Superlight 2 Review: The Safe DefaultThe 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.Sennheiser HD 560S Review: The Footstep HeadphoneA wide, precise, near-reference open-back at a mid price — the strongest value pick for competitive positional audio.
