Product description
The essentials
If you want a wireless gaming mouse that doesn’t feel like a brick in your hand, the Logitech G G309 LIGHTSPEED is built around a lightweight approach. It combines Logitech G’s low-latency LIGHTSPEED wireless with Bluetooth, so you’re not forced into one single connection style at the desk.
The headline details on paper are pretty convincing: a HERO 25K sensor for very precise aiming, LIGHTFORCE hybrid optical-mechanical switches for gaming responsiveness, and long battery life that’s designed to keep you focused on play rather than charging. It’s also positioned as a lighter option within the gaming mouse world, which can matter if you swap grip styles or you simply prefer less weight over long sessions.
That said, it’s not perfect for everyone. If you strongly prefer a heavier, more inertia-driven feel, or if you’re expecting the kind of extra software-driven customisation some mice lean on, you may find this is more “practical lightweight gaming” than “max tinkering”.
Key takeaways
The G309 aims at people who want wireless flexibility without sacrificing accuracy or responsiveness. The key things you’ll be buying into are the lightweight design, the HERO 25K sensor (with submicrometre tracking claims and no smoothing), and LIGHTFORCE hybrid switches that blend optical speed with mechanical tactility.
For everyday use, that combo often translates to mouse movements that feel controlled, not mushy, and clicks that respond quickly. If you play online titles where small aim corrections and fast reactivity matter, the spec set makes sense.
Where it shines for gaming
This mouse’s strongest argument is consistency in the things players actually notice: aiming precision, click feel, and how it stays out of the way. The HERO 25K sensor is described as delivering submicrometre precision tracking without smoothing. On top of that, the LIGHTFORCE hybrid switches are designed for “optical speed” with a mechanical touch.
In a practical sense, that means you can do micro-adjustments during target tracking—think holding a crosshair steady on a head-height area and making tiny corrections rather than large sweeping moves. And when you’re snapping to targets, the switch approach is meant to keep your button presses feeling immediate.
Wireless options and battery reality
The G309 doesn’t just offer one connection mode. It switches between LIGHTSPEED wireless (positioned as solid and low-latency) and Bluetooth. This is useful if you move between a gaming PC and a laptop, or if you want Bluetooth for general work while keeping LIGHTSPEED for gaming.
Battery life is another major talking point. It’s stated as 300 hours with an AA battery, and also “unlimited” with POWERPLAY. If you don’t want to think about battery management, that’s a clear advantage—though it also depends on whether you already have POWERPLAY set up (the entry mentions it as an option rather than something included).
There’s also a weight angle: it’s described as 86 g with the AA battery included, and 68 g without the battery. That matters if you’re sensitive to how much the mouse weighs during long sessions or if you switch between tighter and looser grips.

What you’ll notice day to day
The 6 programmable buttons are there for in-game shortcuts and workflow shortcuts. In practice, that can mean binding things like weapon select, push-to-talk, or commonly used actions so you’re not reaching for the keyboard.
It’s also built around “lightweight” rather than “feature-heavy bulk”. If you’re the kind of player who values comfort and speed of movement over having a heavier, more stabilising mouse, this will likely feel more natural.
Worth noting though: the entry doesn’t list any specific software features or profiles, so if you care deeply about highly granular button tuning and on-the-fly profile switching, you’ll want to double-check what your setup supports before committing.
Should you buy it?
Buy it if you want a lightweight wireless gaming mouse with low-latency LIGHTSPEED plus Bluetooth, and you’re specifically interested in a high-precision HERO 25K sensor paired with LIGHTFORCE hybrid switches. It also suits players who prefer fewer distractions—especially if battery life and weight are your top priorities.
You may want to skip it if you’re after a heavier mouse feel, or if your purchase decision depends on details that aren’t covered here (for example, the depth of software customisation, or whether POWERPLAY is already part of your setup). If POWERPLAY isn’t in your ecosystem, the “unlimited” battery claim won’t be the same kind of certainty.
For who it’s for, it sits in the kind of “serious but sensible” bracket: a gaming-first wireless mouse that leans into accuracy, responsive clicking, and comfort through lower weight—rather than trying to be everything at once.
