G304 Lightspeed

Overview

The Logitech G304 Lightspeed is the best budget wireless gaming mouse ever made. Released in 2019, it brought Logitech’s LIGHTSPEED wireless technology — the same low-latency connection found in the $150+ G Pro Wireless — down to a $39.99 price point. It uses Logitech’s HERO 12K sensor, runs on a single AA battery with up to 250 hours of claimed battery life, and wraps it all in the classic G Pro shell shape. The G304 (known as the G305 in some markets) targets budget-conscious gamers who want wireless freedom without the latency penalty of Bluetooth. It has earned near-universal recommendation as the entry point for wireless gaming mice. The tradeoff is weight: at approximately 99g with an AA battery, it is significantly heavier than modern wireless alternatives. If weight does not bother you and your budget is under $50, the G304 remains remarkably compelling years after its release.

Design & Build Quality

The G304 uses Logitech’s classic egg-shaped shell design, inherited from the original G Pro wired mouse. The PC/ABS shell has a matte coating that is fingerprint-resistant and provides adequate grip. There is no RGB lighting — a practical decision that contributes to the extraordinary battery life.

The construction is solid for the price. The shell has no perceptible flex under normal pressure, and the main buttons are firm without wobble. The overall build feels dense and well-assembled — Logitech’s manufacturing quality is evident even at the budget tier.

Dimensions are 116.6mm long, 62.15mm wide, and 38mm tall. This is a compact, egg-shaped mouse with a symmetrical design that accommodates both left-handed and right-handed users. The rounded profile with a centered hump is one of the most neutral mouse shapes available — it does not aggressively favor any particular grip style.

The battery compartment houses a single AA battery under the top shell. The battery adds significant weight — a standard AA Duracell brings the total to approximately 99g. Switching to a AAA lithium battery with a foil adapter can reduce weight to approximately 83g, which is a popular modification among competitive G304 users. This weight reduction comes at the cost of some battery life, but given the mouse’s 200+ hour endurance, the tradeoff is worthwhile.

The shell is available in black and white, with occasional limited-edition colorways in some markets. The design is clean and understated — no flashy logos, no RGB strips, no honeycomb cutouts.

The bottom of the mouse houses the battery compartment, the power switch, and a storage slot for the LIGHTSPEED USB receiver. The receiver storage is a thoughtful inclusion that prevents the tiny dongle from getting lost during transport.

Shape & Grip Compatibility

The G304 measures 116.6mm long, 62.15mm wide, and 38mm tall. This is a compact egg shape with a centered hump — the same basic geometry as the classic Logitech G Pro wired mouse.

Palm Grip (16.5-18.5cm hands): The G304’s compact size limits palm grip to small-to-medium hands. At 116.6mm, there is enough length for hands up to approximately 18.5cm to achieve full palm contact. The 38mm centered hump fills the palm adequately, and the 62.15mm width provides comfortable side contact for hands 8.0 to 9.5cm wide. If your hands are 17 to 18cm, palm grip on the G304 feels natural and secure — the egg shape cradles your palm, and the moderate hump prevents your hand from going flat. Hands over 18.5cm will find the mouse too small for comfortable palm grip, with fingers overhanging the front edge and the rear not reaching far enough into the palm. The 99g weight (with AA battery) adds stability during palm grip, which some players appreciate — the mouse sits solidly on the pad without feeling skittish.

Claw Grip (16.0-18.0cm hands): Claw grip is the G304’s sweet spot. The centered hump positions perfectly against the rear of your palm in a claw hold, and the 116.6mm length provides comfortable finger arching over the main buttons. At 62.15mm wide, the sides are easy to pinch for lifting and repositioning. The classic egg shape is one of the most proven claw grip geometries in gaming mouse history — millions of CS players have used variations of this shape over the past two decades. For hands in the 16.5 to 17.5cm range, claw grip on the G304 feels immediately familiar and controllable. The main limitation is weight — 99g is heavy for claw grip compared to modern 50-60g alternatives. Rapid flick shots require more effort, and extended sessions may produce more fatigue than with a lighter mouse.

Fingertip Grip (15.5-17.0cm hands): Fingertip grip is possible but limited by weight. The compact dimensions are appropriate for fingertip control — the short 116.6mm length and low 38mm profile keep the mouse under your fingertips without shell-palm contact. However, 99g (or 83g with AAA lithium mod) is heavy for pure fingertip play, where you rely on finger muscles alone to move the mouse. For casual fingertip users, it works. For competitive fingertip players who value agility, the weight is a significant handicap. The PTFE feet on the G304 are also basic, which means initial friction during micro-adjustments is higher than on premium mice.

Hand Width Considerations: Recommended hand width is 8.0 to 9.5cm. The 62.15mm body is comfortable for average-width hands and manageable for slightly narrower or wider dimensions. Players with very wide hands (10.5cm+) will find the sides too narrow for secure grip.

Sensor Performance

The HERO 12K sensor is Logitech’s older proprietary sensor, supporting DPI from 200 to 12,000 with a maximum tracking speed of 400 IPS and 40g acceleration tolerance. At competitive settings (400-1600 DPI), the sensor performs well — no acceleration, no smoothing, and reliable tracking on common cloth pads. The HERO 12K was designed for power efficiency, which is why the G304 achieves such extraordinary battery life.

The HERO 12K is not the latest sensor in Logitech’s lineup — the HERO 2 (found in the G Pro X Superlight 2) and HERO 25K (found in the G502 X Plus) offer higher DPI ceilings and refinements. However, for competitive play at typical DPI ranges, the performance difference between the HERO 12K and newer sensors is negligible. You will not notice the sensor as a limiting factor in gameplay.

Click latency is approximately 2.0ms, and motion latency is approximately 5.5ms. These are adequate numbers for competitive play, though they trail behind the sub-4ms motion latency of newer mice. The LIGHTSPEED wireless connection adds essentially zero latency compared to wired — Logitech’s wireless technology has been independently verified as equivalent to wired performance.

Lift-off distance is approximately 1.2mm and not adjustable via hardware. Through Logitech G HUB software, you can fine-tune surface calibration to optimize tracking for your specific mousepad.

The sensor works reliably on cloth and hybrid pads. Hard pad and glass pad compatibility is limited compared to newer sensors.

Switches & Buttons

The G304 uses Omron mechanical switches rated for 10 million clicks. The 10M durability rating is the lowest in Logitech’s current lineup — the G Pro X Superlight 2 uses switches rated for 100 million. In practical terms, 10 million clicks is approximately 2-3 years of heavy daily gaming. The actuation force is approximately 60 grams-force, which is on the heavier side. The click feel is standard Omron — crisp and reliable, with moderate pre-travel and a defined tactile event.

The Omron switches in the G304 are susceptible to the double-click issue that affected many Omron switches from this era. If you use the mouse heavily for 2+ years, you may develop double-click problems. Switch replacement is possible for users comfortable with soldering.

The scroll wheel is a mechanical stepped design with medium-heavy notch resistance. Each step is clearly defined, and the wheel does not feel loose or rattly. The heavier resistance prevents accidental scrolls during gameplay. The scroll wheel click requires moderate force — intentional enough to avoid accidental middle-clicks.

Two side buttons are positioned on the left side. They are well-placed for thumb access, with crisp clicks and appropriate travel. The button surfaces are slightly textured for tactile identification.

A DPI button sits behind the scroll wheel, cycling through preset DPI stages. It is slightly recessed to prevent accidental actuation.

Total button count is six: left click, right click, scroll click, two side buttons, and DPI cycle.

Connectivity & Battery

The G304’s standout feature is its LIGHTSPEED wireless connectivity at $39.99. LIGHTSPEED uses 2.4GHz frequency hopping with a proprietary protocol that delivers 1ms report intervals at 1000Hz — indistinguishable from wired in every independent latency test. This is the same wireless technology found in mice costing 3-4x more.

The USB receiver is compact and can be stored inside the mouse’s battery compartment during transport. The receiver requires a USB Type-A port. There is no USB-C dongle or Bluetooth connectivity — the G304 is LIGHTSPEED-only.

Battery life is exceptional. Logitech claims 250 hours on a single AA battery. Real-world usage typically yields 180-220 hours depending on polling rate and usage patterns. At 1000Hz polling, expect approximately 200 hours. Dropping to 500Hz extends battery life further. The battery indicator in Logitech G HUB provides remaining charge estimates.

The AA battery form factor has pros and cons. On the positive side: batteries are universally available, cheap, and instantly replaceable — no waiting for a recharge. On the negative side: the weight. A standard AA battery adds approximately 23g, bringing the total to approximately 99g. The popular modification of using a AAA lithium battery (Energizer Ultimate Lithium AAA with a foil adapter) reduces weight to approximately 83g while maintaining 100+ hours of battery life.

There is no wired mode — the G304 cannot function with a USB cable. If the battery dies, you need a replacement battery to continue using the mouse.

Feet & Glide

The G304 ships with two PTFE feet — one large foot around the sensor and one at the front. The feet are basic and thin (approximately 0.6mm). The glide is adequate on cloth pads but noticeably rougher than the smooth, rounded-edge PTFE found on premium mice. At 99g, the increased weight also affects glide — more weight means more friction against the pad surface.

Aftermarket feet are available and highly recommended. Corepadz and Tiger Arc offer G304-specific PTFE replacements that significantly improve glide smoothness. This is a $5-10 upgrade that materially improves the daily experience.

The two-foot design is less stable than a four-foot layout during diagonal movements, though in practice most users do not notice a meaningful difference.

Software

The G304 uses Logitech G HUB for configuration. G HUB allows you to adjust DPI settings (in 50 DPI increments), polling rate (125/250/500/1000Hz), button assignments, and surface calibration. G HUB is a heavier application than some competitors’ software but provides comprehensive control over all Logitech peripherals.

The G304 supports one onboard memory profile. You can configure your settings in G HUB, save them to the mouse, and uninstall the software. The onboard profile stores DPI, polling rate, and button assignments. For most competitive players, this one-profile approach is sufficient — you set your preferred settings and forget about it.

G HUB’s surface calibration feature is worth using. It optimizes the sensor’s tracking characteristics for your specific mousepad, which can improve lift-off distance behavior and tracking consistency. Run the calibration once per mousepad and save the result.

Pro Player Usage

The Logitech G304 does not have documented usage among professional esports players in our current tracking database. This is expected — professional players at the top tier universally use premium peripherals, often through sponsorship agreements that provide the latest hardware. The G304’s weight (99g) and older sensor disqualify it from consideration at the professional level, where every gram and millisecond matters.

However, the G304 has massive adoption among semi-competitive and ranked players. In online communities, the G304/G305 is the most frequently recommended budget wireless mouse. It appears regularly in discussions from high-ranked players in Valorant, CS2, and Apex Legends. These players chose the G304 because it provides LIGHTSPEED wireless at a price point where the only alternatives are Bluetooth mice with higher latency.

The G304 occupies a unique position in the market: it is the mouse that proves you do not need to spend $150+ to get competitive-grade wireless. For players whose aim is limited by skill rather than hardware (which is the vast majority of players at every rank), the G304 provides 95% of the experience at 25% of the price.

What the G304’s widespread adoption reveals is that wireless connectivity matters more to most players than weight. The G304 is 40g heavier than a Superlight 2, but it outsells the Superlight 2 many times over because of its price accessibility.
