ENDGAME GEAR XM1 RGB Gaming Mouse with PMW3389 Sensor and RGB Lighting

The ENDGAME GEAR XM1 RGB Gaming Mouse with PMW3389 Sensor and RGB Lighting is a wired mouse built by a German brand for competitive play. This article goes beyond the spec sheet to cover grip fit, trade-offs, and the mistakes buyers usually make.

Overview

The short version: this is a mouse for FPS players who are fine with a cable and want low weight plus a crisp click. It uses the PixArt PMW3389 optical sensor (up to 16,000 CPI), custom Kailh GM 4.0 switches rated for 60 million clicks, weighs about 79 g, and comes in white.

The shell is ambidextrous, with three RGB zones (wheel, logo, bottom ring) and 14 LEDs total.

It is a poor fit if wireless freedom, quiet clicks, or heavy macro use are your priorities. There are only five buttons, so there is no MMO-style side cluster.

Spec numbers only get you so far: actual fit depends on hand size and grip style, which the sections below address.

Compatibility Guide

Connection is wired USB-A only, with a braided cable roughly 1.8 m long.

It is plug-and-play on Windows, macOS, and Linux — basic tracking and clicking work without drivers. Saving CPI profiles, tuning the RGB zones, and remapping buttons require the Endgame Gear Configurator, which targets Windows and macOS.

On Linux, expect "works fine, limited configuration."

The real friction is usually not the OS but the port. Thin laptops and some small-form desktops ship with USB-C only, so you may need an adapter or hub.

That works, but cheap hubs can make polling inconsistent — plug straight into a USB-A port on the machine when you can.

Cable routing matters too. 1.8 m is enough for a normal desk, but if your PC sits far back under the desk it can feel tight.

Braided cable is stiffer than flexible silicone-style cable, so it tugs more. A mouse bungee — or even just clipping the cable at the desk edge — changes the feel noticeably.

This is the classic thing people only discover after buying a wired mouse.

Mousepad choice counts as compatibility as well. The PMW3389 has adjustable lift-off distance and tracks reliably on cloth and most hard pads, but glass pads and high-gloss surfaces can confuse it.

That is a trait of optical sensors generally, not a flaw specific to this model.

Product Info

Pricing moves. The captured Amazon figures were ￥9,980 on 18 June 2026 and ￥13,036 on 26 August 2026 — over ￥3,000 of movement on the same listing in two months.

Treat any price in this article as a snapshot only and check the live listing before buying; sales and point promotions shift it further. Marketplace listings such as eBay depend entirely on stock.

On reception: as of the 18 June 2026 capture, the Amazon listing showed 324 reviews averaging 4.4 out of 5 stars (about 88% positive).

For a niche-brand wired mouse, 324 reviews is a meaningful sample. A 4.4 average is the classic "most people are happy, a minority are not" range — and the Before You Buy section below covers what that minority tends to complain about.

As specs: PixArt PMW3389 optical sensor, up to 16,000 CPI, five buttons, Kailh GM 4.0 switches rated at 60 million clicks, three RGB zones with 14 LEDs, roughly 1.8 m cable, about 79 g, wired USB-A, white finish.

It launched in late 2020, so this is a mature design rather than a cutting-edge one — predictable behaviour, not headline specs. Accessories and warranty terms can vary by seller, so confirm those on the listing.

How It Compares

Its position has shifted since 2020. Back then 79 g counted as lightweight; today 55 g wireless mice are ordinary options.

So the comparison is not really about absolute weight — it is about how you value the cable.

Wired means no charging, no 2.4 GHz congestion in radio-busy rooms, and no battery mass.

The cost is the cable itself, which is why bungee use is effectively part of the purchase.

Spend the same budget on wireless and you can get something lighter with a newer sensor. Some rivals advertise 25K or 26K CPI, but most players actually sit between 400 and 1600 CPI, so 16,000 is never the limiting factor.

Maximum CPI is close to useless as a comparison metric — judge on shape, weight, click feel, and cable instead.

What Actually Shapes the Experience

The character of this mouse comes from the Kailh GM 4.0 switches and the shell more than the sensor.

GM 4.0 has a firm actuation and a sharp, audible click.

That helps prevent accidental clicks and suits players who tap-fire, but it is a clear negative if you stream with a close mic or play late at night beside someone sleeping. This is not a silent-switch mouse, and no setting changes that.

The symmetrical shell is not aggressively contoured, so palm and claw grips both work. But symmetrical does not mean left-handed: side buttons sit on one side only, so a left-hand grip puts them under your ring finger.

If you need true dual-side buttons, check this first.

The RGB — three zones, 14 LEDs — is adequate in count but less elaborate than what big-brand suites offer. The upside is that the Configurator is light on system resources, which suits people who hate background software.

The downside is that you cannot sync it into a whole-PC lighting ecosystem.

Best Use Cases

• FPS and battle royale players who accept a cable: 79 g plus a stable wired link is an easy combination for both flicking and tracking, and lift-off distance is adjustable.
• Players who want a decisive click: the firm GM 4.0 feel suits tap-firing, and the 60-million-click rating supports long-term use.
• People who avoid background software: it works driver-free, and the config tool is lightweight.
• White-themed setups: the white finish fits a light-coloured desk without clashing.

Before You Buy

Price first. The same listing went from ￥9,980 in June 2026 to ￥13,036 in August 2026.

If you budgeted around ￥10,000, timing can break that assumption — and at the higher figure, lighter new-generation wireless mice enter the comparison. Decide your ceiling before you open the listing, and do not trust a captured price as current.

This is a 2020 design. Maturity is an advantage, but the lightweight segment has moved a long way since.

If low weight itself is your goal, newer models will satisfy you more than 79 g will.

The click is not quiet. GM 4.0 is loud and crisp by design.

For late-night play with housemates, close-mic streaming, or shared office use, look elsewhere — this cannot be tuned away.

Left-handed users should check button placement. Tracking is fine either way, but side buttons on one side only means the left-hand experience is not equivalent.

A note on listing data. Amazon product pages sometimes carry incorrect manufacturer, model-number, or category entries, and occasionally show details belonging to a different product.

Confirm from the images and title that you are buying the white ENDGAME GEAR XM1 RGB. If a displayed price looks unnaturally low or high for this class of mouse, you may be looking at a different variant or item.

Budget for cable management. A wired mouse only feels as light as its cable routing allows; factoring in a bungee or cable clip changes real-world satisfaction.

FAQ

Q. Do I need the software? A.

No. It works driver-free over USB-A.

The Configurator is only needed for CPI profiles, RGB tuning, and button remapping.

Q. Does it work on Mac or Linux? A.

Basic function is fine anywhere with a USB-A port. The config software targets Windows and macOS, so Linux users lose fine-grained customisation.

Q. Do I need 16,000 CPI? A.

Almost certainly not. Most FPS players use 400–1600 CPI.

Treat the maximum as headroom, not a buying criterion.

Q. Can left-handed players use it? A.

The shell allows it, but with side buttons on one side only it is not a true ambidextrous button layout.

Q. What about a USB-C-only laptop? A.

An adapter or hub works, though cheap hubs can cause inconsistent behaviour. Direct USB-A is safest.

Q. Is the click silent?
A. No. Kailh GM 4.0 produces an audible, sharp click. Choose another model if quiet operation is required.
