Endgame Gear OP1 8K v2 Review: The Wired Featherweight
★★★★ 4.4/5Reviewed 2026-06-16
A 49.5 g wired flick mouse that skips the wireless tax entirely — native 8K over the cable, no dongle, no battery. The small narrow shell is the whole pitch: brilliant for claw and fingertip, wrong for big palm hands.

Product verdict — build, value & fit, not win-rate.
The good
- +49.5 g in a low, narrow, ambidextrous shell — genuinely tiny in the hand
- +Native 8000 Hz straight over the cable, no separate dongle or charging
- +PAW3950 sensor — flawless tracking, nothing to fault in the input chain
- +Mid-priced: cheaper than the wireless flagships it competes with on weight
The catch
- −It's wired — that's the trade you make versus the wireless flagships
- −Small and narrow: too cramped for large hands or a full palm grip
- −8K is a bonus, not a reason to buy — most players won't feel it past 2K
AimBench insight
Wired at 49.5 g, it undercuts most wireless flagships on both weight and price — if you don't need cordless, a paracord cable plus a bungee makes it feel wireless for less money.

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 96/100, #2 of 6 in the Value class — effectively tied with the picks above it (sub-perceptual gaps).
Best-built score
Measured engineering quality, normalised within the Value price class — not win-rate.

The OP1 8K v2 makes a deliberate choice that most flagships avoid: it stays wired. In return you get a 49.5 g mouse with native 8000 Hz polling straight over the cable — no dongle, no battery, no charging. For a player who already ran a paracord-soft cable and never loved wireless, that's not a compromise, it's the point.
The shape is the whole story
At 118.5×59.6×36.4 mm this is a small, narrow, low-bodied mouse, and that defines who it's for. Claw and fingertip grippers with small-to-medium hands get a shell that vanishes under fast aim. Big-handed palm grippers should look elsewhere — there's simply not enough mouse here to fill a large hand. Check the mouse-by-hand-size ranker before you commit.
What the money and the grams actually buy
Be clear about what's real here. The PAW3950 and 49.5 g clear the competitive floor — but so does every modern flagship. Lower weight helps only up to a point, and the effect is small and saturating; you're not buying win-rate by the gram. The 8K polling is a bonus on top of an already-flawless input chain, not a reason to pick this over a 2K mouse — see our polling-rate breakdown. What you're really paying for is the shape, the build, and the wired-featherweight niche it owns.
