Couple this with a mechanical tension system for each button and it just feels like a workhorse. Every gaming mouse in recent memory for Logitech receives this top-of-the-line technology as acceleration is instantaneous. Under the hood of the G604 brings the 16K HERO sensor that allows for extreme accuracy and precision with up to 16,000 DPI. This can be a bit touchy at times, but honestly this wheel is one of the more underrated features that Logitech implements. The wheel can be locked down for more precision or be unlocked and allow for ridiculous scrolling. This allows for two additional buttons by pushing the wheel left or right. The G604 also includes the Dual-Mode hyper-fast scroll wheel.
These are set for DPI adjusting by default and sit in a good location that won’t feel like a chore when trying to use them. Much like the G602, there are two other buttons on the far left of the left-click button. Each button is customizable via the Logitech G Hub as macros can also be programmed for each button. There’s also no need to worry about pressing the buttons in by accident as each button is almost designed like a switch and requires effort to click. These six buttons sit double stacked and are slightly curved as the design caters to the thumb. This Logitech mouse allows for thumb resting on the interior portion of the mouse which makes six of the buttons accessible. The shell of the G604 is comprised of a matte black plastic while the palm, thumb and two end fingers provide grip from a rubber gripping. While the G604 may lack RGB and the modern look of a gaming mouse, what it packs under the hood is remarkable.
Its fifteen programmable buttons, Bluetooth and the ability to hot swap the Lightspeed add a ton of options for more than just gaming. It may just be the best combination of a gaming mouse and an advanced office user mouse there is. Building upon the structure of the G602 and more akin to the popular G502, the G604 keeps things low key but offers a ton of mechanical options for its users. Logitech is always looking to evolve its mice designs with new looks and technology and the recently announced G604 Lightspeed Wireless Gaming Mouse follows that same trend.
