The Logitech G203 LIGHTSYNC is a great wired gaming mouse. It feels very well-built, and it has extremely low click latency. It also has a wide CPI range, and you can adjust the set CPI by increments of 50. It isn't ideal for larger hands using a palm or claw grip, but it should be comfortable for all hand sizes using a fingertip grip. It has RGB lighting zones in the logo and three independent zones in a band that runs around the back. The companion software offers plenty of customization options and is compatible with Windows and macOS. Unfortunately, while its predecessor, the Logitech G203 Prodigy, has onboard memory, this mouse doesn't.
Our Verdict
The Logitech G203 LIGHTSYNC is satisfactory for office use. It feels well-built, has a good number of programmable buttons, the software is compatible with Windows and macOS, and it's well-suited for smaller hands. However, those with large or extra-large hands may not find a palm or claw grip comfortable due to its short length. Unfortunately, you can't use this mouse wirelessly, and the mouse wheel lacks L/R tilt buttons and doesn't unlock for free scrolling.

The Logitech G203 LIGHTSYNC is decent for MMO gaming, but it doesn't have nearly as many buttons as a dedicated MMO mouse, and the cable isn't very flexible. It feels well-built and has remarkably low click latency and a low lift-off distance. Those with larger hands likely won't be able to use the mouse comfortably using a claw or palm grip, but a fingertip grip should be comfortable for all hand sizes. The software offers plenty of customizable options, it's compatible with Windows and macOS, and it allows you to set a secondary layer of commands by assigning a G-Shift button.

Compared To Other Mice
The G203 LIGHTSYNC gaming mouse is an update of the Logitech G203 Prodigy. The LIGHTSYNC has three independent RGB zones in the band around the back, while the Prodigy has one. Unfortunately, while the Prodigy has onboard memory for custom profiles, the updated LIGHTSYNC doesn't. This mouse offers solid performance and can be a good choice if you're looking for a budget option and you prefer a fingertip grip or have smaller hands.
For other options, see our recommendations for the best wired mouse, the best cheap gaming mouse, and the best Logitech mouse.
The Logitech G305 LIGHTSPEED and the Logitech G203 LIGHTSYNC are very similar gaming mice but have a few standout differences. The LIGHTSYNC scores better for gaming across the board, but it's wired only, has a narrower CPI range, and while it has a somewhat better click latency, most people likely won't notice a difference. Despite scoring lower, the LIGHTSPEED may be a better gaming mouse for some. It connects wirelessly with a USB receiver but is heavier since it's powered by an AA battery. It doesn't have RGB lighting, but this may not bother some people. Lastly, while both mice use the same software, the LIGHTSPEED has onboard memory for custom settings. Both mice are well-suited for all hand sizes using a fingertip grip, and only those with larger hands may find a palm or claw grip uncomfortable.
The Logitech G203 LIGHTSYNC and the Razer DeathAdder Essential are wired gaming mice, but the Logitech is a better choice if you prefer lighter, ambidextrous-shaped mice. Also, it has a wider CPI range, a more precisely adjustable CPI, a lower lift of distance, and a much lower latency. Comparatively, you may find the Razer's larger, right-handed shape more comfortable when using a palm or claw grip if you have larger hands.
The Logitech G203 LIGHTSYNC and the Logitech G305 HERO are both wired gaming mice, but the G305 HERO performs better overall. It's much more comfortable to use thanks to its right-handed slant and thumb rest. It also has more programmable inputs, a wider CPI range, and a scroll wheel that unlocks for free scrolling. On the other hand, the G203 LIGHTSYNC is much lighter and has comparably good click latency. However, it doesn't have onboard memory like the G305 HERO.
The Razer Viper Mini and the Logitech G203 LIGHTSYNC are comparable wired gaming mice. The Razer is significantly lighter and has much better click latency. It also has better mouse feet, a more flexible cable, and onboard memory. The Logitech has a lower lift-off distance, you can set the CPI by more precise increments, and the sensor is more consistent. Both mice are ideal for smaller hands but very well-suited for a fingertip grip, regardless of hand size. That said, the Logitech is slightly more accommodating of larger hands using a palm or claw grip.
The Logitech G203 LIGHTSYNC is an update of the Logitech G203 Prodigy. The two mice are nearly identical, but the LIGHTSYNC has three independent RGB zones within the band that wraps around the back, while the Prodigy only has one. The LIGHTSYNC also has a somewhat lower click latency, but most people likely won't notice a difference. Although it's the older model, the Prodigy has onboard memory for settings, but the LIGHTSYNC doesn't.
The SteelSeries Rival 3 and the Logitech G203 LIGHTSYNC are great wired gaming mice with comparable performance. The SteelSeries is lighter, has a marginally higher maximum CPI, has onboard memory for settings, and has quieter mouse clicks. The Logitech has much better click latency, a CPI that you can set more precisely, and a lower lift-off distance. If you have small hands and prefer using a fingertip grip, the Logitech will likely be more comfortable. If you use a claw grip but have extra-large hands, the SteelSeries may be more suitable because of its longer body. Both mice are only suitable for a palm grip for small or medium-sized hands.
The GLORIOUS Model D has comparable performance to the Logitech G203 LIGHTSYNC. The GLORIOUS is a right-handed mouse that's significantly lighter, has a more flexible cable, better mouse feet, and a wider CPI range. The GLORIOUS is best suited for a palm grip for any hand size and suitable for a claw or fingertip grip for larger hands. On the other hand, the Logitech feels better-built, has an ambidextrous shape, a lower lift-off distance, a more adjustable CPI, and a somewhat better click latency. It's best suited for a fingertip grip for any hand size and a palm or claw grip for smaller hands.
The Logitech G203 LIGHTSYNC Is a better wired gaming mouse than the Redragon M602 Griffin RGB Wired. The Logitech is lighter and feels sturdier. It also has a more flexible cable, a wider CPI range, a much lower lift-off distance, much lower click latency, and a CPI you can adjust precisely, compared to the Redragon, which has irregular CPI adjustment steps. Additionally, the Logitech software is compatible with Windows and macOS, while the Redragon software is only compatible with Windows. On the other hand, the Redragon has a thumb and pinky rest, which the Logitech lacks. It also has an additional reprogrammable button behind the scroll wheel.
The Logitech G705 is a wireless, right-handed gaming mouse designed for small hands, while the Logitech G203 LIGHTSYNC is a wired-only, symmetrically shaped gaming mouse that's well-suited for use with a fingertip grip with all hand sizes. Since the G705 is a higher-end mouse, it has more features like onboard memory, wireless versatility, and higher-quality feet. Performance-wise, though, both mice perform equally well.
The Logitech G203 LIGHTSYNC and the Microsoft Sculpt Ergonomic Mouse are designed for different uses. The Logitech is a budget, wired gaming mouse, so it has RGB lighting, better click latency, and a higher polling rate. It also has more customization features for the sensor. On the other hand, the Microsoft is better suited for office or productivity tasks. It's wireless and has an internal storage compartment for its receiver. It also has L/R scroll wheel tilts for horizontal scrolling and has a more comfortable ergonomic design with a thumb rest.
