Origin One X

Overview

The Ninjutso Origin One X is a 39g wired gaming mouse that delivers the classic Zowie EC ergonomic shape in one of the lightest packages ever produced. Released in 2022, it targets a very specific audience: players who have spent years on EC-series mice and want that exact shape at an extreme weight reduction. At 39g, the Origin One X is lighter than the Finalmouse Starlight-12 (42g) — making it one of the absolute lightest gaming mice in existence.

Ninjutso is a small enthusiast brand without the marketing reach of Razer or Logitech. The Origin One X lives in the mouse enthusiast community — recommended on r/MouseReview, discussed on mouse Discord servers, and known to players who track the ultralight category obsessively. If you have never heard of Ninjutso, that is expected. If you have, you probably already know exactly why this mouse matters.

Design & Build Quality

The Origin One X achieves its 39g weight through a honeycomb shell design. The hexagonal cutouts cover portions of the top shell and bottom, removing material while maintaining structural geometry. The PC/ABS shell is thinner than typical gaming mice, contributing to the extreme weight savings.

The matte coating is simple and functional. It provides adequate grip without any special treatment — no soft-touch, no antibacterial, no grip texture. For a mouse this light, coating texture matters less because your hand is not fighting against weight when gripping.

Build quality is solid considering the weight and price point. There is some flex when pressing the honeycomb areas — inherent to any perforated shell at this weight — but the mouse does not creak or feel fragile. For a small brand, Ninjutso has executed the honeycomb construction competently. The shell holds together under normal gaming use without complaints.

The paracord cable is thin and flexible, comparable in quality to aftermarket paracord replacements that enthusiasts install on other mice. With a mouse bungee, the cable drag is minimal. The Origin One X’s 39g weight means cable drag has a proportionally larger effect on mouse movement than it would on a heavier mouse, making a bungee essentially mandatory for competitive play.

The bottom features four PTFE feet, a DPI button, and a sensor lens. There is no software switch or wireless dongle because this is a wired-only mouse.

Shape & Grip Compatibility

The Origin One X measures 126mm long, 60mm wide, and 38mm tall. The shape is a faithful reproduction of the Zowie EC2 — a right-handed ergonomic form with a pronounced rear hump, left-side thumb groove, and right-side flare. For anyone familiar with EC-series mice, the Origin One X will feel immediately recognizable.

Palm Grip (18.0-20.0cm hands) — EXCELLENT: The EC-clone shape is historically one of the best palm grip designs in gaming. The Origin One X’s dimensions provide full palm contact for medium-to-large hands. The rear hump fills the center of your palm, the thumb groove guides your thumb into a natural position, and the right-side flare supports the ring and pinky fingers.

For hands measuring 18.0-20.0cm in length and 9.5-10.5cm in width, the Origin One X provides comfortable palm grip that feels identical to the Zowie EC2-C in shape — but at 39g instead of 73g. That 34g weight reduction transforms the palm grip experience. Slow tracking movements that required deliberate effort on a 73g mouse become effortless. Lift-and-reset cycles feel like moving air.

The EC2 proportions (126mm length, 60mm width) are slightly smaller than the Razer DeathAdder V3 (128mm, 68mm), which means the Origin One X suits medium hands better than large hands. Hands over 20cm may find it slightly narrow at 60mm.

The 39g weight fundamentally transforms the palm grip experience compared to the original EC2-C at 73g. Every movement requires less effort, lifts are effortless, and extended sessions produce significantly less wrist fatigue. The weight reduction is proportionally larger than the difference between most mice on the market — going from 73g to 39g represents a 47% reduction. Your hand mechanics change at this weight. Deliberate, forceful movements become unnecessary; the mouse follows your hand’s natural micro-movements with zero resistance.

Claw Grip (17.5-19.5cm hands): Good for relaxed claw grip. The ergonomic hump supports the palm heel while allowing fingers to curl over the front buttons. The 38mm height is lower than the DeathAdder V3 (44mm), which reduces the tendency of the mouse to push your hand into palm grip. For claw grip users who want some ergonomic support without full palm commitment, the Origin One X hits a good balance.

The 39g weight is exceptional for claw grip flicking — the mouse responds instantly to wrist movements with almost no inertia. Rapid micro-adjustments feel precise and effortless.

Fingertip Grip (17.0-19.0cm hands): Adequate but not ideal. The ergonomic shape is inherently broader and taller than symmetrical mice designed for fingertip control. The 60mm width and right-side flare can interfere with the lateral finger movements that fingertip grip relies on. If fingertip is your primary grip, a symmetrical mouse like the Pulsar X2 V2 is a better choice — but the 39g weight does make fingertip possible for players who adapt.

Sensor Performance

The PixArt PAW3395 sensor delivers a DPI range of 400 to 26,000, maximum tracking speed of 400 IPS, and 40G acceleration tolerance. Lift-off distance is adjustable through Ninjutso’s software and defaults to approximately 1.2mm.

The PAW3395 is a proven, flawless gaming sensor. In the Origin One X, it performs identically to implementations in the Endgame Gear XM2w and Pulsar X2 V2 — no spin-out, no acceleration, no smoothing at any DPI level. The sensor is tournament-ready and competitive with any mouse on the market.

Click latency measures approximately 2.5ms and motion latency approximately 6.0ms. These numbers are behind the best current mice (Razer Viper V3 Pro at ~1.0ms) but within acceptable competitive range. The PAW3395’s low power draw also means the sensor runs cool, which contributes to tracking consistency during long sessions.

The 1.2mm default LOD is on the higher side. If you play at low sensitivity and frequently lift the mouse, adjusting the LOD downward through software is recommended. At 0.8-1.0mm, the tracking cutoff during lifts feels more natural for competitive FPS play.

Switches & Buttons

The Origin One X uses Kailh GM 8.0 mechanical switches, rated at 80 million clicks. The actuation force is approximately 55 grams-force with a crisp, reliable tactile break. Kailh GM 8.0 is one of the most respected mouse switches in the enthusiast community, and Ninjutso’s choice here demonstrates awareness of what their target audience values.

The click consistency is good — left and right clicks feel similar in force and travel, though without the pre-sorting that Endgame Gear applies to the XM2w’s switches. The click feel is slightly heavier than Razer’s optical switches but provides more tactile feedback, which some players prefer for confirmation that a click has registered.

Side buttons on the left wall provide adequate clicks. They are not the most tactile side buttons available — some play exists in the button travel — but they function reliably for ability binds and utility usage. The scroll wheel uses a standard mechanical encoder with medium resistance and defined steps. For a $89.99 mouse, the switch and button quality meets expectations.

Connectivity & Battery

The Origin One X is wired only. The paracord cable uses a thin, flexible construction with a USB-A connector. The cable is one of the better stock cables available — flexible enough that, with a bungee, it approaches the feel of wireless for most movements.

There is no battery, no wireless technology, and no Bluetooth. The wired-only design keeps weight to the absolute minimum and eliminates any wireless-related concerns. For the target audience — enthusiasts who prioritize weight above all else — the wired design is a feature, not a compromise.

At 39g, cable drag has a proportionally larger impact on the mouse feel than it would on heavier mice. A mouse bungee is strongly recommended. Without one, the cable’s weight relative to the mouse creates noticeable resistance during large swipes.

Feet & Glide

The Origin One X ships with four PTFE feet, each approximately 0.8mm thick. The glide is smooth on cloth pads and good on hard pads. The feet quality is adequate — not premium-tier but above generic stock feet.

Aftermarket feet from Corepad and Tiger Arc are available and recommended by the enthusiast community for an improved glide experience. The foot dimensions match common EC2-compatible sizes, so aftermarket options designed for the Zowie EC2-C work directly on the Origin One X without modification. Given the Origin One X’s 39g weight, the glide characteristics of your feet matter more proportionally than on heavier mice — the mouse has so little mass that foot friction becomes a larger percentage of the total resistance you feel during movement.

Software

The Ninjutso Software is basic and functional. It provides DPI configuration, polling rate selection, LOD adjustment, and button remapping. The interface is minimal with limited visual design.

The mouse supports 1 onboard memory profile. The software is designed to be used briefly for configuration and then closed — there is no ecosystem integration, no RGB management, and no advanced features. For the Origin One X’s target audience, this simplicity is acceptable. You set your DPI, adjust your LOD, and close the software.

The LOD adjustment is particularly important for the Origin One X. The default 1.2mm LOD is higher than ideal for competitive FPS play. Reducing it to 0.8-1.0mm through the software should be your first configuration step. At 39g with a lower LOD, the lift-and-reset cycle becomes incredibly fast — the mouse practically teleports from one position to another without tracking unwanted movement during the lift phase.

Pro Player Usage

The Ninjutso Origin One X does not have documented professional esports adoption. Ninjutso is a small enthusiast brand without sponsorship infrastructure or pro team relationships. The mouse exists entirely within the enthusiast community.

However, the EC shape it replicates is one of the most historically significant shapes in esports. The Zowie EC2 has been used by professional CS players for over a decade. Players like device (Astralis) and Hakis (NIP) have competed at the highest level with EC2 variants. The Origin One X carries that shape DNA at a fraction of the weight.

The competitive case for the Origin One X is weight-focused. At 39g, it offers the most extreme weight reduction available in an EC-style ergonomic mouse. For players who believe that lighter is always better and who have already validated their preference for the EC shape through years of play, the Origin One X is the logical endpoint.

Community discussions position the Origin One X as a “shape validation” mouse — players who have tried many mice, identified the EC2 as their ideal shape, and want to push that shape to its absolute lightest. It is not a first mouse or a safe recommendation. It is a mouse for players who know exactly what they want.

The Origin One X also highlights an interesting market dynamic: small enthusiast brands can out-innovate major manufacturers in specific niches. Zowie, the creator of the EC shape, has not produced a sub-40g EC variant. Razer’s DeathAdder V3, while lighter than previous DeathAdders, weighs 59g wired. Ninjutso, with fewer resources and less brand recognition, achieved a 39g EC-clone that neither Zowie nor Razer offers. This is possible because small brands can target niche audiences that major brands cannot justify serving — the 39g honeycomb EC market is too small for Razer’s production scale but perfectly sized for Ninjutso’s.

For players considering the Origin One X, the key question is not “is this a good mouse?” but “have I validated the EC shape as my preferred shape?” If the answer is yes and you want it lighter than anyone else offers, the Origin One X delivers. If you are still exploring shapes, start with the Zowie EC2-C or DeathAdder V3 — they are more widely available, easier to return, and represent the shape in its most polished form.

Verdict & Buying Guide

Buy if: You are an EC-shape enthusiast who wants the absolute lightest version of that shape available. At 39g with a PAW3395 sensor and Kailh GM 8.0 switches, the Origin One X is the ultimate expression of “EC shape, minimum weight.” Palm grip users with 18.0-20.0cm hands who have validated their EC shape preference will find this mouse exceptional.

Skip if: You want wireless, you have not tried an EC-shape mouse before (start with the Zowie EC2-C instead), or you dislike honeycomb shells. The Origin One X is an enthusiast product for players who have exhausted mainstream options and want something extreme.

Alternatives:

• Razer DeathAdder V3 Pro ($149.99) — Premium wireless ergonomic, 64g, different shape but same category
• Pulsar Xlite V3 Wireless (~$89.99) — Wireless EC-inspired shape, lighter than most, better availability
• Zowie EC2-C (~$69.99) — The original EC2 shape, wired, trusted by professionals

Price Assessment: At $89.99, the Origin One X is fairly priced for what it offers. A 39g PAW3395-equipped EC-clone with Kailh switches is a niche product, and the price reflects the small-batch manufacturing of an enthusiast brand. If the EC shape is your validated preference and you want minimum weight, the Origin One X delivers value that no mainstream brand currently matches.

The Origin One X is a mouse for the end of your search, not the beginning. It assumes you have already tried EC-style mice, confirmed the shape works for your hand, and decided that lighter is better. If those conditions are met, the 39g weight and faithful EC2 shape execution make the Origin One X one of the most targeted, purposeful gaming mice available. It does one thing — provide the EC shape at minimum weight — and it does that one thing exceptionally well.

For the broader market, the Origin One X also serves as proof of concept for what small, enthusiast-focused brands can achieve. The mouse market benefits from companies like Ninjutso that serve niches too small for major brands to address. If the Origin One X validates sufficient demand for ultralight EC-clones, it may push Zowie or Razer to produce their own sub-50g ergonomic variants — which would benefit the entire community regardless of brand preference.
