The Logitech G203 LIGHTSYNC is a great wired gaming mouse. It feels very well-built, and it has very 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 it's compatible with Windows and macOS. Unfortunately, while its predecessor, the Logitech G203 Prodigy, has onboard memory, this mouse doesn't.
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.

That said, it feels well-built and has very 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.
The Logitech G203 LIGHTSYNC is very good for fans of ultra-light gaming, but it's heavier than dedicated ultra-light mice, and its cable isn't very flexible.

However, it isn't suitable for larger hands using other grip types.
The Logitech G203 LIGHTSYNC is inadequate for travel. It isn't very portable, it may not fit into most laptop bags, and you can't use it wirelessly.

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 well-suited for all hand sizes using a fingertip grip, and only those with larger hands may find a palm or claw grip uncomfortable.
