The Logitech G903 HERO is a great gaming mouse. It's an upgrade over the Logitech G903 LIGHTSPEED because it features the HERO 25K sensor, which provides a very wide CPI range that you can adjust in small increments. It has low click latency whether you're using it over its USB receiver or wired, it has a high maximum polling rate, and the sensor remains consistent when moving at a fast speed. It's well-built, glides smoothly, and its ambidextrous design should feel comfortable for most people using any grip. Sadly, it's heavy and not designed for ultra-light gaming, but it comes with a 10-gram weight if you want to make it even heavier.

Our Verdict

8.2 Office/Multimedia

The Logitech G903 HERO is great for office use. It's well-built and comfortable to use whether you're left or right-handed. You can reprogram almost any of its buttons and you can unlock the wheel for infinite scrolling. It's wireless, but can only be used wirelessly with its proprietary receiver, and not Bluetooth.

Pros
  • Comfortable shape.
  • Well-built.
  • Scroll wheel can be unlocked for infinite scrolling.
Cons
  • Can only connect wirelessly through its USB receiver.
8.0 Video Games (FPS)

The Logitech G903 HERO is great for FPS gaming. It has low click latency whether you're using it wired or wirelessly. It has a very wide CPI range and the sensor is very consistent when you move it quickly. It's well-built and comfortable to use, but unfortunately, it's a heavy mouse.

Pros
  • Very low click latency.
  • Glides smoothly.
  • Minimal CPI variation.
  • Very wide and adjustable CPI range.
Cons
  • Heavy and bulky to carry around.
8.5 Video Games (MMO)

The Logitech G903 HERO is excellent for MMO gaming. Although it doesn't have as many side buttons as most MMO gaming mice, it has an excellent number of programmable inputs. It has low click latency, a wide CPI range that you can adjust in small steps, and it has a high maximum polling rate.

Pros
  • Comfortable shape.
  • Very low click latency.
  • Very wide and adjustable CPI range.
Cons
  • Only two side buttons.
7.0 Ultra-Light Gaming

The Logitech G903 HERO is decent for ultra-light gaming. It's much heavier than most ultra-light mice, and there's not much weight optimization to make it lighter. However, it has low click latency and glides around smoothly thanks to its good feet and flexible cable.

Pros
  • Very low click latency.
  • Glides smoothly.
Cons
  • Heavy and bulky to carry around.
6.9 Travel

The Logitech G903 HERO is okay for travel use. It's wireless, but it may be too bulky to carry around and doesn't have a slot to store the USB receiver. However, it's well-built, comfortable, and you can use it either with Windows or macOS.

Pros
  • Comfortable shape.
  • Well-built.
Cons
  • Heavy and bulky to carry around.
  • No storage for USB receiver.

The Logitech G903 HERO looks exactly like the Logitech G903 LIGHTSPEED. It has an ambidextrous shape with an aggressive gamer design. It's mainly made out of matte plastic, but there are glossy accents on the side buttons and near the scroll wheel. There are independent RGB zones below the CPI switch buttons and on the Logitech branding on the back.

The Logitech G903 HERO is front-heavy, but you can add a 10-gram weight in the back to even out the balance. You can also remove the plastic covering for the weight, the side panel, and the side buttons if you want to make it somewhat lighter.

Build Quality

This mouse has great build quality. It's well-built and the plastic body feels solid. The scroll wheel is made of metal with a rubber grip, and it wobbles when you shake the mouse because it has a tilt feature. The button that unlocks the infinite scrolling wobbles a bit as well. The side buttons and side panels detach magnetically, and they don't wobble at all when attached.

Differences Between Sizes And Variants

We tested the Logitech G903 HERO in black, which is the only color available. The Logitech G903 LIGHTSPEED is an extremely similar mouse, but with a different sensor. You can see the label for our unit here.

Compared To Other Mice

The Logitech G903 HERO is a great gaming mouse that's a nice upgrade over the Logitech G903 LIGHTSPEED. However, it's not as light and versatile as some other options, like the Razer Viper Ultimate. Also see our recommendations for the best gaming mouse, the best wireless mouse, and the best Logitech mouse.

Logitech G903 LIGHTSPEED

The Logitech G903 HERO and Logitech G903 LIGHTSPEED are the same but with different sensors. The HERO has a higher max CPI and less CPI variation, while the LIGHTSPEED has a lower minimum CPI.

Logitech G502 LIGHTSPEED

The Logitech G903 HERO is slightly better for gaming than the Logitech G502 LIGHTSPEED, but both are great versatile mice with the same sensor. The G903 has an ambidextrous design and a narrower shape that's well-suited for more hand-sizes. It's also a little bit lighter, has slightly lower click latency, and its feet provide a better gliding experience. On the other hand, the G502 feels better-built and is more comfortable overall, thanks to its ergonomic shape and thumb rest.

Logitech G Pro Wireless

The Logitech G Pro Wireless is slightly better overall than the Logitech G903 HERO, but they use the same sensor. The G Pro is smaller, lighter, feels better-built, and the feet provide a better gliding experience. However, the G903 has a better, braided cable, you can unlock the scroll wheel for infinite scrolling, and it has more buttons.

Logitech G502 HERO

The Logitech G903 HERO is slightly better than the Logitech G502 HERO, but they have the same sensor. The G903 is wireless, and it's better suited for those with small hands using the claw or palm grip. However, the G502 is wired, feels better-built, and is more comfortable overall.

Razer Viper Ultimate

The Razer Viper Ultimate is better for most uses than the Logitech G903 HERO. The Razer has slightly lower click latency, is more comfortable, and has much better feet, so it glides better. However, the Logitech has a higher max CPI, less CPI variation, and the G HUB software is available on macOS, while the Razer Synapse 3 software isn't.

Logitech G900 Chaos Spectrum

The Logitech G900 Chaos Spectrum is a predecessor of the Logitech G903 HERO. The G903 HERO includes an optional 10g weight so you can center the weight distribution. It also has a much higher maximum CPI range, a more consistent sensor, and better click latency. Both mice are very well suited for all grip types, but small hands may struggle to reach all buttons using a fingertip grip.

Mad Catz R.A.T. 4+

The Logitech G903 HERO is a better gaming mouse than the Mad Catz R.A.T. 4+. The Logitech feels sturdier and has an ambidextrous shape. It connects with its charging cable or wirelessly with its USB receiver. It has mouse feet that glide more smoothly, and it has one additional side button and four more buttons total. It also has a wider CPI range, much lower click latency, and software compatible with Windows and macOS, while the Mad Catz only has software compatible with Windows. On the other hand, the Mad Catz is a wired-only mouse that's a bit lighter and has a right-handed shape with an adjustable palm rest.
