The Logitech G604 Lightspeed 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 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.See our Video Games (FPS) recommendations
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 Lightspeed wireless gaming mouse 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 Lightspeed 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.
The Logitech G604 Lightspeed wireless gaming mouse 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 Lightspeed 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 Lightspeed wireless gaming mouse is a bit too long for people with smaller hands. It might be difficult to reach some side thumb buttons.
The Logitech G604 Lightspeed 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 Lightspeed 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 Lightspeed's 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 Lightspeed 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.
Amazing compatibility for the Logitech G604 Lightspeed wireless gaming mouse. The software is downloadable on Windows and macOS, meaning you can customize your controls to whatever you like on both platforms.
The Logitech G604 Lightspeed 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.
