The Logitech G604 is versatile for a wide range of uses. It's designed for gaming, with a low wireless latency when used with its receiver or Bluetooth, and 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, some people with smaller hands might not like the ergonomics due to its long shape.
Great for mixed usage. This mouse has plenty of features that are great for gaming and some for the office. It has many programmable buttons and its wireless latency isn't too high for more casual gamers. It's also a good travel companion due to its built-in receiver holding and wireless design.
Great for the office. This mouse has great ergonomics, especially when using the palm grip. However, people with smaller hands might have trouble having nice control over it due to its long shape. On the upside, it has plenty of programmable buttons and you can even unlock the wheel for infinite scrolling, which is very useful in long documents.
Great for traveling. Thanks to its great wireless compatibility, this mouse can be used with its receiver or over Bluetooth, which is very versatile. It isn't the smallest mouse, but being able to use it without a cable is great when on a plane.
Decent for FPS games. While its wireless latency is very low, its quite heavy and won't be ideal for very quick flick shots. On the upside, it has great ergonomics, but might be a bit too big for small hands, and isn't ideal for the fingertip grip. Its performance is excellent and can be easily customized to your preference inside the dedicated software.
Amazing for MMO games. This mouse has plenty of programmable buttons, and you can even set a button that triggers another set of commands for as long as you hold it, giving you even more options. Its performance is amazing, but unfortunately, its body is a bit long, making it hard to use a fingertip grip, or to use if you have small hands.
This mouse is pretty heavy and isn't recommended if you're looking for an ultra-light gaming mouse.
The Logitech G604 almost looks like an office mouse rather than a gaming one. There's a subtle Logitech G logo on the back of it 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.
The Logitech G604 is quite heavy and won't be a good option for ultra-light gaming. There's also no way of significantly reducing its weight.
This mouse is decently portable. Its body is rather big, but at least it can be used wirelessly, and you store the receiver inside the mouse. This makes it easier to simply toss it in a traveling bag. 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 ergonomics of this mouse are great 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 and the CPI switching buttons are a bit awkward to use at first since they're on the left-click button. Some might also have difficulty differentiating each side button, as their shape is quite uncommon. This layout is fine for office-related work, but isn't optimal for gaming like a dedicated MMO mouse is.
The Logitech G604 is a bit too long for small hands when using a palm grip. There are better gaming options for small hands, like the Corsair Scimitar Pro.
When using the claw grip, the Logitech G604 is a bit too long for people with smaller hands. It might be difficult to reach some side thumb buttons.
The Logitech G604 isn't recommended for fingertip grip, as only larger sized hands will be able to have decent control and reach all buttons.
The Logitech G604 has amazing wireless connectivity. It can be used via Bluetooth and with a dedicated receiver, and you can switch between those two sources with a single press of a button on the top of the mouse. Unfortunately, it doesn't have a rechargeable battery, so you'll need to purchase AA batteries, although it does come with one.
This mouse can't be used wired.
The Logitech G604's click latency is very low, both when using its dedicated receiver, or with a Bluetooth connection. Most people won't notice any delay when playing games.
The Logitech G604 LIGHTSPEED's performance is amazing. It has a very large CPI range, which you can adjust fairly precisely to your preference. It also has an adjustable polling rate and can give you a very smooth cursor movement.
The Logitech G604 has plenty of programmable buttons. Only the Bluetooth/receiver switch and the wheel lock buttons can't be switched. On the upside, you can even program the up and down scroll and the mouse's left/right tilt. You can also set a G-Shift button in the software to trigger alternate keybindings as long as you hold that button.
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 Logitech G HUB is an impressive piece of software and it allows plenty of customization options. You can also 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.
The Logitech G604 stands out thanks to its ergonomic design that fits pretty much every hand size and all grips. However, it's a bit bulky and the side buttons aren't the easiest to press, so people with small hands might prefer looking elsewhere. This wireless mouse has amazing performance, although its latency is higher than some other gaming-oriented mice, and it can't be used wired, which is disappointing.

The Logitech G604 LIGHTSPEED is a better mouse than its previous version, the Logitech G602. It has overall better performance and is slightly more comfortable to use. It only uses a single AA battery, while the G602 requires two. You can also unlock the scroll wheel on the G604 for infinite scrolling.
The Logitech G604 LIGHTSPEED performs better than the Logitech MX Master 3, but the ergo shape of the MX Master 3 might be better suited for the office. These two wireless mice are very well-built, but the MX Master 3 feels very premium. If you want many side buttons, go with the G604, but if you want a side-scrolling wheel, go for the MX Master 3.
The Logitech G604 LIGHTSPEED is much better than the Logitech G603 LIGHTSPEED. The G604 is more comfortable, it has lower click latency through its receiver, it has a wider CPI range, and there are many more side buttons. However, the G603 is better-built and it's smaller, making it easier to carry around.
The Logitech G903 LIGHTSPEED is a better gaming mouse than the Logitech G604 LIGHTSPEED. It's noticeably lighter, although still a bit heavy, and better built. The G903 is compatible with a lot of different hand sizes and grips. It comes with a charging cable, but can't be used via Bluetooth like the G604.
Overall, the Logitech G604 LIGHTSPEED is better than the Logitech G703 LIGHTSPEED Wireless Gaming Mouse with HERO sensor; however, they're very different mice. The G604 is much heavier, and it has a lot more buttons, making it more suitable for MMO games. It also has a scroll wheel that supports tilt inputs and can be unlocked for infinite scrolling. On the other hand, the G703 is lighter and has weight optimization, and it can be used wired or wirelessly.
The wireless Logitech G604 LIGHTSPEED is a better mouse than the wired Logitech G502 HERO, but the G502 will be better for gaming. The G604 has more side buttons and is very comfortable to use, while on the other side, the G502 is slightly better built and features RGB lighting.
The Logitech G604 LIGHTSPEED is a better all-around mouse than the Logitech G502 LIGHTSPEED, but for gaming, the G502 is better. The G604 has six side buttons while the G502 has two, with a sniper button. You can also customize the G502's weight and it can be used wired as well.
