The Logitech G604 LIGHTSPEED is quite versatile and performs well for a wide range of uses. It's designed for MMO gaming and has a low click latency. It has amazing overall performance, but its shape and features are also well-suited for the office. It has plenty of programmable buttons and is a nice overall improvement over the Logitech G602. However, its long shape may not be suitable for people with smaller hands.
Our Verdict
The Logitech G604 LIGHTSPEED is excellent for the office. This mouse feels very comfortable, especially when using a palm grip.

Compared To Other Mice
The Logitech G604 LIGHTSPEED is an amazing and quite versatile mouse that stands out thanks to its comfortable design and impressive performance. It’s one of the few mice that we’ve tested that have both a very wide CPI range and amazing consistency. However, it’s rather bulky and heavy compared to many other gaming mice, and the buttons can feel a bit hard to press. On the plus side, unlike many other manufacturers, Logitech's companion software is compatible with both Windows and macOS, which is great.

The Logitech G305 LIGHTSPEED and the Logitech G604 LIGHTSPEED are for different uses. The G305 is good for FPS gaming. It’s much smaller and lighter than the G604 and has an ambidextrous design that’s well-suited for a fingertip grip. The G604 is a good choice for MMOs, with six buttons on the side and a total of 29 programmable inputs. It’s heavy and wide, so people with smaller hands may struggle to reach all the buttons. Both mice are wireless-only, but the G604 supports Bluetooth, while the G305 doesn't.
The Logitech G604 LIGHTSPEED is much better than the Logitech G603 LIGHTSPEED. The G604 is more comfortable, has lower click latency through its receiver, has a wider CPI range, and has many more side buttons. However, the G603 is better-built, and it's smaller, making it easier to carry around.

It's lighter than the Logitech, and it's particularly well-suited for a palm grip, though people with medium or large hands can also use it with a claw or a fingertip grip. On the other hand, you can only use the Logitech wirelessly. It's an excellent choice for MMO gaming, with six side buttons and 29 programmable inputs. It's also versatile enough to use for work or while traveling. It has a better sensor with a wider CPI range, a lot less CPI variation, and better click latency.

It also has much better mouse feet and better overall gaming performance. On the other hand, the Logitech has software compatible with Windows and macOS, while the Razer only has software compatible with Windows. The Logitech also uses AA batteries for power, while the Razer recharges with a USB-C cable.
The Razer Naga Pro is better for most uses than the Logitech G604 LIGHTSPEED.

It’s heavier and better suited for medium or large hands. It has six side buttons and a total of 29 programable inputs. On the other hand, the Razer is designed for FPS gaming, though it performs better as an office mouse.

The Corsair SCIMITAR RGB ELITE is an outstanding MMO gaming mouse, but the Logitech G604 LIGHTSPEED is more versatile. The Logitech connects wirelessly with a USB receiver or via Bluetooth. It also has six buttons and has a thumb rest. Comparatively, the Corsair is a wired mouse with an adjustable 12-button side panel and a pinky rest. The Corsair is well-suited for all grip types and nearly all hand sizes, while the Logitech is suitable for all grip types but likely more comfortable for larger hands.
Test Results
The Logitech G604 almost looks more like an office mouse than a gaming one. There's a subtle Logitech G logo on the back, and there isn't any RGB lighting. It has an ergonomic design with a thumb rest and alternates between different shades of black. Unfortunately, no other color variants are available.
It's decently portable. Its body is rather big, but at least it can be used wirelessly, and you can store the receiver inside the mouse. This makes it easier to toss in a laptop bag, but if you want a slightly more portable option, check out the small Logitech G603 LIGHTSPEED.
The Logitech G604 has a great build quality. The mouse wheel wobbles and rattles a bit, but this might be due to its ability to tilt. Other than that, the materials feel solid and you have good latex grips on the top and thumb rest.
The Logitech G604 is very heavy and isn't a great option for fast-paced gaming. There's also no way of significantly reducing its weight apart from using a battery adapter to allow you to use AAA batteries instead of AA batteries, which is how the Lowest Weight test result is obtained. If you're looking for a significantly lighter multi-genre mouse, check out the SteelSeries Aerox 5 Wireless.
This mouse feels very comfortable for right-handed people. The side buttons and thumb rest are on the left side, and the mouse has a slanted design to the right. The thumb buttons are fairly easy to access, although you need to move your thumb upwards for every click as it doesn't rest on any button. The CPI switching buttons are also a bit awkward to use at first since they're on the left-click button.
The Logitech G604 has fantastic wireless connectivity. It can be used via Bluetooth and with the dedicated receiver, and you can switch between those two sources with the single press of a button on top of the mouse. Unfortunately, it uses one AA battery for power, so you'll need to change it eventually.
This mouse can't be used wired and doesn't have any cable included.
Even if the mouse is pretty heavy, the feet are good and glide well on a mousepad and, even better, directly on a desk. There aren’t any extra feet included with the mouse, but you should be able to find some third party replacement ones if needed.

The Logitech G604 has a total of 15 buttons, with six on the left side. The Bluetooth/receiver switch and the wheel lock buttons can't be reprogrammed, but all others can, including the left click, though it’s not easy to reassign it. You can also set a G-Shift button on the mouse to trigger another layer of commands for as long as you press it, ending up with 29 programmable inputs.
The Logitech G604's click latency is low. You won't notice a delay while playing reaction-based or competitive games.
The sensor on the Logitech G604 LIGHTSPEED has a very wide CPI range that's adjustable by increments of 50. The lift-off distance is low enough to ensure that it won’t register any movement while you reposition your mouse, and you can set the polling rate at 125Hz, 250Hz, 500Hz, or 1000Hz.
This mouse's wheel is amazing. It offers great feedback when it's locked and it can also be unlocked for infinite scrolling, which is great when going through very long documents. This mouse also allows for tilt commands, which can be programmed to whatever you want.
The mouse clicks are quiet, and shouldn’t disturb people around you even if you're in a very noise-sensitive environment.
The Logitech G HUB is an impressive piece of software that allows for plenty of customization options and that's compatible with both Windows and macOS. You can set a G-Shift button, which triggers a second set of controls for as long as you hold the set button. The mouse also has onboard memory, meaning you can set your settings on a computer and keep them when connecting to another. While there were no problems using this software during testing, many users online have reported issues using Logitech's G HUB, including but not limited to freezing, startup problems, and connection difficulties with certain devices. If you'd like to share your experience using Logitech G HUB with this mouse, feel free to leave a comment in the discussions.
Remarkable compatibility for the Logitech G604. The software is downloadable on Windows and macOS, so you can customize your controls to whatever you like on both platforms. All the mouse's buttons work fully on both OS as well.
