Two years have passed since the release of the Logitech G900 Chaos Spectrum wireless gaming mouse ($85.09 on Amazon), which established decreased latency as a standard that mice of its kind should strive for. The Chaos Spectrum used the same Lightspeed wireless technology as the brand-new Logitech G305 Lightspeed Wireless Gaming Mouse ($59.99), except for the name. According to Logitech, it will only take one millisecond (ms) from the moment you press a button until your favorite space shooter’s alien vessel is destroyed. Although we were unable to test it precisely, our hands told us that this wireless gaming mouse is really fast.
It’s also rather simple. Many of the capabilities that you would anticipate from a high-end wireless gaming mouse, such as the Logitech G903 Lightspeed ($81.99 on Amazon), are absent from the Logitech G305 Lightspeed. The G305’s greatest strength is that it transfers the wireless capabilities of that game-changing mouse to a reasonably priced accessory that both gamers and non-gamers will value for its simple design, long battery life, and remarkable real-world performance.

Logitech G305 Lightspeed: A Lightweight, High-Performance Gaming Mouse Without the Frills
Touching the Logitech G305 Lightspeed rather than just looking at it is what makes it so appealing. Both its matte black and white finishes aren’t very homey, but it won’t be much more impressive than other, more powerful versions in Logitech’s catalog.
In order to accommodate your palm, the 1.5-by-2.5-by-4.6-inch (HWD) form begins curled at the heel and narrows as you approach the two front mouse buttons. Rolling the rutted scroll wheel between the primary buttons produces a rough, tactile response. There is a sensitivity button aft of the wheel that lets you adjust the tracking resolution, which goes up to 12,000 dpi.
The G305 Lightspeed weighs 3.42 ounces, which is comparable to other mice in its class. For instance, the HyperX Pulsefire FPS (available on Amazon for $34.63) weighs 3.3 ounces, while the Roccat Kova weighs 3.5 ounces. In contrast, the Razer Mamba, a more expensive and Editors’ Choice wireless rival to the G305 Lightspeed, weighs a relatively “whopping” 4.32 ounces. Despite being powered by an AA alkaline battery concealed inside its shell, the G305 is very light.

By the way, if you first can’t locate the 2.4GHz USB dongle, it’s because it’s kept secure inside the mouse itself, to the left of the battery. Pressing down on the back of the mouse shell and sliding it off will give you access to both items. Note that the only wireless transmission option for the G305 Lightspeed is the USB receiver, which you may tuck inside the provided USB extension cable if necessary. There is no Bluetooth functionality for this mouse.
The Logitech “G” emblem is located at the back of the mouse and, of course, stands for “Gaming.” The lack of vibrant lights shining through that insignia will be noticeable to gamers used to more gaudy mouse. Customization is restricted to the two buttons on the left side of the G305 Lightspeed because it does not have any LED frippery. These are pre-programmed to your browser’s forward and back buttons, but you may set them to any mouse function, keystroke, or multi-key macro you can think of by installing the Logitech Gaming Software (LGS) application.
The G305 Lightspeed’s bottom has the same optical sensor with the “Hero” logo that is used in Logitech’s more costly mouse. With a resolution range of 100dpi to 12,000dpi, you can’t anticipate the same level of versatility as the Razer Mamba, which has a maximum resolution of 16,000dpi. In contrast to what you can truly see, it’s primarily a numbers game at the high reaches of mouse resolution.
Furthermore, a lot of gamers contend that acceleration and tracking speed are more crucial specifications than DPI. You can rely on a top speed of 400 inches per second (IPS) for the mouse to precisely track movement, especially with the G305 Lightspeed. However, the G305 Lightspeed is only capable of tracking your precise movements at a maximum gravitational force of “40G.” In this sense, the Razer Mamba, which costs $30 more than the G305 Lightspeed, falls short in the speed-spec sweepstakes at 210 IPS even if its acceleration is greater at 50G.
These figures won’t mean much to most people, with the exception of e-sports players, since unless you’re so furious about your colleagues’ performance that you throw the G305 Lightspeed across the room, I doubt you’ll be moving your mouse more than thirty feet in a second. (And frankly, that’s simply bad sportsmanship.) Regarding the gravitational-force threshold, any force between 30 and 50 grams is sufficient to detect the sudden jerks and shocks of your hand.
Logitech G305 Lightspeed Review: High-Performance Wireless Gaming Mouse with Long Battery Life and Customization Features
I’ve tested the Logitech G305 in Fortnite and Wolfenstein II: The New Colossus, and I don’t see any performance differences between it and my Razer Basilisk (which costs $96.31 on Amazon) at home. However, I believe Logitech was aiming for that: a wireless mouse with a latency low enough to blend in with the cable mice used in first-person shooters and competitive gaming. I can aim in all directions and move my cursor across the screen just as quickly as I can with the Basilisk, which is impressive for a gaming mouse in this price bracket.
Just now, we brought up the AA battery. According to Logitech, the AA cell in the G305 Lightspeed has a 250-hour battery life. That is only true, though, when the mouse is in LGS’s normal Performance setting. Alongside it is an additional setting known as Endurance mode. According to Logitech, when enabled, the battery life increases to nine months, but the reaction time increases from one millisecond to eight milliseconds; in other words, one of the trade-offs for preserving battery life is an increase in latency.

Overall, I was surprised to find that the two modes seem rather different. The pointer marginally trails my motions in Endurance mode, but it seems much more like genuine 1-to-1 tracking in Performance mode.
The G305 comes with a disposable AA Duracell that has to be replaced when the battery life drops to 15%. This is indicated by a red flashing light beneath the sensitivity button. Other than that, LGS has a gray symbol with a five-bar battery gauge in the top left corner. The battery gauge on the Logitech G305 Lightspeed has not dropped a single bar in Performance mode for the week that I’ve been using it.
According to Logitech, the G305 Lightspeed’s switches can endure 10 million clicks, which is half as much as the G603 Lightspeed’s rating ($0.00 on Amazon). We’ll have to believe Logitech as it would take years to investigate that claim, but the G603’s higher endurance rating indicates that the G305 Lightspeed employed a switch with a lower power consumption. Similarly, Logitech claims that the G305 Lightspeed has “advanced button tensioning,” which is marketing jargon meaning “the buttons require less force to click than other gaming mice on the market.” In actual use, I couldn’t tell the difference between the HyperX Pulsefire Surge and the Logitech G305 Lightspeed’s click force. In addition, I saw very little resistance in contrast to the Razer Basilisk.
The Logitech G305 Lightspeed has a polling rate between 125 and 1,000 Hz. (We tested at 1,000 Hz as usual.) You can change the polling rate in LGS, as well as the DPI “steps” and the amount of sensitivity levels you may access with the specialized DPI-switcher button. Additionally, you may select from the LGS home menu whether you want the settings for the G305 Lightspeed to be saved in the mouse’s on-board memory or on your computer. For example, this may be helpful while traveling for gaming events.

Last but not least, the Input Analysis option in LGS essentially does the same thing I observed when I examined the mechanical Logitech G513 Carbon keyboard ($129.99 at Walmart). This sub-menu offers you the Key Press Heat Map and Key Duration Heat Map choices. After you manually start and end a mouse-button “recording session” that you wish to examine, LGS records your button presses over an arbitrary amount of time. The software then gives you a summary of how many times you pressed each button during the session (Key Press Heat Map) and for how long (Key Duration Heat Map).If you want to monitor your fire rate or the amount of time you spend pointing while in sniper mode, this might be useful. It’s mostly a curiosity, though.
Conclusion
To sum up, the Logitech G305 Lightspeed Wireless Gaming Mouse is a unique product in the gaming peripheral industry that offers great performance at a reasonable price. It rivals even more expensive versions in terms of responsiveness and latency, thanks to Logitech’s cutting-edge Lightspeed technology, which is necessary for competitive gaming. It is a flexible option for both casual users and gamers because to its small size, low weight, and effective Hero optical sensor.
Its simplicity is a virtue rather than a drawback, even if it lacks key high-end capabilities like Bluetooth connectivity and RGB lighting that can be adjusted. The G305 achieves a great mix between lifespan and usefulness with an amazing 250-hour battery life in Performance mode and the option to prolong it further in Endurance mode. Additionally, its on-board memory and adjustable DPI settings provide players on-the-go versatility.
The Logitech G305 Lightspeed shines at providing dependable performance and value, even if it might not be appealing to those looking for dazzling looks or great adaptability. This gadget is a good option for anyone looking for a wireless gaming mouse that is simple to use and has great accuracy and responsiveness.
