The G305 has on-board memory, so it carries all its settings from the Logitech Gaming Software. If you’re having an issue with the connection, there is a receiver extension included in the box so you can always move the receiver slightly to avoid issues. I didn’t test the range, but I never lost connection even in areas where there were a lot of devices using the 2.4ghz band. It’s as simple as plugging in the dongle and turning the mouse on. The wireless connection is flawless, like most Logitech Wireless mice these days. I have been using the mouse for bordering on two months now with a AAA battery, and it hasn’t shown signs of dying yet. The mouse is powered by an AA battery, though you can use a AAA with a converter or tin-foil. The mouse has an endurance mode, with a slower polling rate and thus response time, and a performance mode, which delivers on the promised 1000hz polling rate and 1ms response time, at the cost of lesser battery life. However, most of the mice don’t have this problem. Keep in mind that there have been reports of the HERO 12K and 16K spinning out from some users – get an RMA if this happens or try to troubleshoot with firmware and connections. It tracks smoothly, with no acceleration or skipping as far as I could tell, and no spin-outs either. During normal use and in-game, I couldn’t tell the difference between it and the PMW-3366 in the Logitech G Pro.

The HERO 12K, like many top optical sensors on the market these days, is almost flawless in terms of performance. However, being a “budget” wireless mouse, what features does it sacrifice for the price? As it turns out, not many. It uses Logitech’s HERO 12K sensor for maximum battery life, and sports a 1000hz polling rate for the same 1ms response time as most wired mice. It takes the basic design of the Logitech G Pro, strips away everything but the necessities, and turns out a no-frills wireless gaming mouse that is great in many ways. The Logitech G305, or G304 in some regions, is currently the cheapest Logitech Lightspeed mouse (based on MSRP) available.
