[OPEN BOX] Logitech G305 Lightspeed Wireless Gaming Mouse - Black / HERO 12K Sensor Zero Smoothing / LIGHTSPEED 1ms Wireless Response / 250-Hour Single AA Battery / 1000Hz Wireless Report Rate / 5 Onboard Profiles 5 DPI Levels / Low-Friction PTFE 250km Feet / OB-910-005283

This video introduces the Logitech G305 LIGHTSPEED Wireless Gaming Mouse, turning the 99-gram shell through every angle and showing the HERO sensor set into the underside. You see the mouse gliding across a desk mat with no cable attached, the two programmable side buttons sitting under the thumb, and the DPI button behind the scroll wheel. This is part number 910-005283.

Here the top shell lifts away to reveal the single AA battery bay and the storage slot that holds the USB nano receiver inside the mouse. That is the entire setup routine on video: drop in one AA, take the receiver out of its slot, push it into a USB port and the LIGHTSPEED link is running. The same slot is where the receiver lives when the mouse goes in a bag.

This clip puts LIGHTSPEED wireless technology into play, following the G305 through fast flicks and slow tracking while the on-screen cursor keeps pace with the hand. Logitech G built LIGHTSPEED to deliver gaming performance over a wireless link, and the footage also runs through the range of vibrant colours the G305 is sold in so you can see how each finish looks.

The HERO sensor developed by Logitech G runs from 200 to 12,000 DPI with no smoothing or filtering applied to your movement, so what the sensor reads is what the cursor does. It is also up to ten times more power efficient than the sensor it replaced. Five customizable profiles each hold five DPI settings, and all of them are stored directly onboard the mouse.

HERO reset what a gaming sensor is expected to deliver, pairing high performance with an energy efficiency that earlier optical sensors could not reach. That combination is exactly what makes a lightweight, durable wireless mouse like the G305 possible in the first place, and it established the standard the rest of the category has been measured against since.

HERO uses intelligent power management, matching how quickly it processes frames to how fast you are actually moving the mouse. Precision holds while the draw on the battery falls away. The result is up to 250 hours of play from a single AA battery, though the exact figure shifts with your own habits and conditions.

The G305 holds its accuracy at tracking speeds beyond 400 inches per second, right across the 200 to 12,000 DPI range. There is zero smoothing, zero acceleration and zero filtering in the signal path, so a fast low-sensitivity swipe lands where you aimed it rather than where an algorithm decided you meant. That is the point of the HERO sensor for serious players.

Latency, connection stability and dropouts are the three problems that historically kept competitive players tied to a cable. Logitech G engineered LIGHTSPEED specifically against all three, and the outcome is a wireless link that performs at wired quality. On the G305 that link runs through the compact USB nano receiver rather than a bulky dongle.

The G305 reports at 1 ms over its wireless connection, matching the polling interval most wired gaming mice run at. Logitech G tested every link in that chain, from the sensor through the firmware to the receiver, because one slow component would undo the rest of the work. The difference shows up most in flick-heavy shooters where a single frame of delay is felt.

HERO and LIGHTSPEED together stretch one AA a long way: up to 250 hours of gaming in the standard mode, or as far as nine months in endurance mode. You switch between the two in Logitech G HUB, and a battery indicator light flags the charge at 15 percent so a swap never catches you in the middle of a match.

The G305 comes in at 99 grams, a figure Logitech G reached by engineering around the battery rather than bolting one on afterwards. Efficient power use meant a single AA was enough, and a single AA is what keeps the shell light. For a wireless gaming mouse that is a low weight, and it shows in long sessions and quick repositioning.

The primary switches are built for a lifespan of 10 million clicks. Around them sit a middle click, a DPI adjustment button and two programmable side buttons, giving six buttons in total that you can remap in Logitech G HUB. Bind a DPI shift, a push-to-talk or an in-game ability wherever your thumb naturally rests and it stays there across profiles.

The left and right buttons are separated from the shell and held under precise mechanical tension, sitting right at the edge of triggering. Less force is needed to complete a click and each press feels the same as the last one. That consistency is what makes rapid repeat clicking predictable during gameplay instead of vague and mushy.

Compact dimensions, a robust shell and a light body make the G305 an easy mouse to travel with, and the USB nano receiver stores inside the mouse instead of rattling loose in a laptop bag. Combine that with the profiles saved onboard and the mouse arrives at a friend's desk or a LAN already configured exactly the way you left it.

The G305 is offered in a wide selection of eye-catching colours, so the mouse can be matched to a desk mat, a keyboard or the rest of a build rather than standing apart from it. This listing covers part number 910-005283. Whichever finish you pick, the HERO sensor, the LIGHTSPEED link and the six programmable buttons are identical underneath.

Put together, the G305 gives you the response of LIGHTSPEED wireless and the accuracy of the HERO sensor in one 99-gram body with six programmable buttons. It suits a competitive player who wants the cable off the desk without giving up tracking, and equally a student or traveller who needs one mouse that runs for months on a single AA.
