In this review
Both mice have lived on my desk. Not at the same time, and not for the same reasons. The G305 rode in a laptop bag for six months of travel and coffee-shop matches. The G502 Hero has been the desk anchor since 2019, the mouse I come back to after every flirtation with something lighter or fancier. They share a sensor family and a Logitech spine and almost nothing else.
The real question is not which is better. They answer different problems. One is a 99-gram wireless budget pick with a 250-hour AA battery. The other is a 121-gram wired war wagon with 11 programmable buttons, a trap-door weight system, and a clutchable scroll wheel that shifts modes. Buyers who conflate the two end up disappointed in whichever one they pick.
So here is the honest breakdown. Same brand, same sensor lineage, wildly different shapes, weights, and use cases. Below is how they measure up on the axes that actually decide aim feel and daily drive.
Quick Verdict
If your grip is claw or fingertip and you move between a laptop and a desk, the G305 wins. If you live at one desk and want 11 buttons plus a free-spin scroll wheel for mixed gaming and productivity work, the G502 Hero wins. The sensor is a wash.

The G305: Wireless That Forgets It Is Wireless
The G305 is the mouse I trust on a table at a Starbucks. It weighs 99 grams with the AA loaded, which sounds heavy next to a 54-gram Viper V3 but feels genuinely light next to any office mouse that ever came with a prebuilt tower. The shell is small and ambidextrous, 116 mm long and 62 mm wide at the palm. Medium hands and a claw grip work. Large hands and a palm grip do not. I learned this the hard way loaning mine to a friend with a 20 cm palm who spent ten minutes complaining before I swapped him onto the G502.
Lightspeed 2.4 GHz is the whole reason this mouse exists at $27. Logitech could have slapped Bluetooth on it and saved five bucks of BOM. They did not. The polling rate matches a wired mouse at 1 ms, and in blind A/B testing during aim-trainer sessions I could not feel the difference. The one catch is dongle placement. Stick the receiver into the back of your tower next to the GPU and you will get micro-stutters on diagonal moves. Logitech ships a short USB extension in the box for exactly this reason. Use it. Put the dongle six inches from the mousepad.
Battery life held up in testing. I got 247 hours on one Eneloop Pro AA before the meter dropped below 10 percent. That is roughly six months of evening gaming for me. There is no wire to manage, no charging dock to buy, and when the battery does die you swap in a fresh AA in 12 seconds.
The compromises are real. Only six buttons. No adjustable weights. Stock feet that wear out in about six months of daily use. And the shape runs small. For the right hand and the right grip style, this is one of the best $27 you can spend on a PC setup. For the wrong hand, it is a frustrating little thing.
The G502 Hero: The Tank That Earned Its Parking Spot
The G502 shape has been in production since 2014. The Hero refresh from 2018 is what you buy today. My current unit has survived two PC builds, one spilled coffee, and a move across three apartments. That history matters because gaming mice are supposed to be disposable and the G502 keeps proving it is not.
The headline is the HERO 25K sensor, which is the same silicon Logitech puts in the $160 G Pro X Superlight. The spec gap between HERO 12K and HERO 25K exists on the box but not under my hand. Both track cleanly at any real-world sensitivity from 400 to 3200 DPI. Both have zero smoothing. Both have the short lift-off distance that matters for cloth-pad players who swipe the mouse off the desk mid-flick.
Where the G502 earns its price is the button layout and the scroll wheel. Eleven programmable inputs sounds like marketing padding until you actually bind them. I run Discord push-to-talk on the sniper button during games, Figma zoom shortcuts on the three thumb buttons for design work, and browser forward and back everywhere else. G HUB’s per-app profile switching does the mode changes automatically. The dual-mode scroll wheel is the feature I thought I did not need. Press the button behind it and the wheel declutches into a free-spin flywheel that takes you from the top of a long codebase to the bottom in one swipe. Click back for tactile notches. I have not found another $50 mouse that does this.
The flaw is the weight. 121 grams without the five removable 3.6-gram weights, 139 grams fully loaded. For wrist-heavy flick aiming at low sensitivity, that is 30 percent more mass than a current competitive flagship. Forearm-based aim compensates for it. Wrist-based aim suffers. If your muscle memory was built on a sub-70-gram shell, switching to the G502 is a three-day recalibration at minimum.
Head to Head
Rating breakdown
Sensor and Aim Feel
The G502 wins on paper with HERO 25K versus HERO 12K, but the extra 13,600 DPI is marketing overhead. Nobody plays at 25,000 DPI. Nobody can. What matters is the tracking behavior at 400, 800, 1600, and 3200 DPI, and both mice are identical there. Zero smoothing. Zero acceleration. Short lift-off distance. A careful wireless receiver placement gets the G305 to wired-feeling latency.
Winner: tie. The sensor is not why you choose between these.
Ergonomics and Grip
The G305 is small and ambidextrous, best suited to claw and fingertip grips on medium or smaller hands. The G502 is larger, right-handed, and contoured for a palm or relaxed-claw hold on medium to large hands. I tested both with two people. The G502 fit my friend with large hands. The G305 fit my partner with smaller hands. Neither mouse fit both.
Winner: depends entirely on your hand. Measure palm-to-middle-fingertip before you buy. Medium hands (17 to 19 cm) can use either.
FPS and Competitive Play
For a competitive FPS at low sensitivity, the G305 beats the G502 by virtue of weight alone. 99 grams beats 121 grams for flick accuracy on cloth pads, full stop. But both are heavier than the current esports default. If you are grinding Valorant or CS2 seriously, both are compromises, and the G305 is the smaller compromise.
Winner: G305.
Productivity and Multi-Button Workflows
This is where the G502 pulls ahead decisively. Eleven buttons plus a free-spin scroll wheel plus G HUB per-app profiles equals a mouse that earns its desk spot during work hours, not just game hours. I cannot bind a Figma hand-tool toggle to a G305 thumb button because there is no second thumb button on the G305. Six buttons is not enough for a work-from-home setup that runs Slack, VS Code, and Ableton on the same mouse.
Winner: G502 Hero, not close.
Build Quality and Longevity
Both mice are built well. The G305 has held up fine for six months of daily use in my case, with the expected mouse-foot wear and no other issues. The G502 has survived five years on my desk with one replaced set of PTFE skates. The G502 is the longer-term bet, partly because of the wired connection (no battery chemistry to degrade) and partly because of the beefier switches. Both Logitechs have historical double-click issues on the older Omron switches. The Hero refresh tightened the G502’s switches. The G305 has held up for me so far.
Winner: G502 by a slim margin, mostly because there is no wireless subsystem to fail.
Who Should Buy What
Buy the Logitech G305 if you want a wireless mouse for a budget build, a travel mouse for a laptop bag, or a second mouse for a couch gaming setup. Medium or smaller hands and claw or fingertip grips get the most out of the shape. Skip it if you have large hands, palm-grip, or if you already own any recent Logitech G wireless.
Buy the Logitech G502 Hero if you want one wired mouse to anchor a desk for gaming and productivity both, if you use more than six shortcuts per app, or if you like the sound of a dual-mode scroll wheel once you understand what it does. Skip it if your wrist already complains after an hour of gaming, or if you want a mouse under 80 grams.
