The Corsair KATAR PRO XT is a lightweight, ambidextrous mouse with two buttons on its left side. It looks physically identical to Corsair KATAR PRO Wireless, except it's a wired mouse and has RGB strips on its scroll wheel. It feels very well-built and comfortable, and its small size is best suited for a claw or fingertip grip. It has a low click latency, a low lift-off distance, and a very wide CPI range that can be precisely adjusted in increments of 1. Unfortunately, the sensor is very inconsistent, and it undershoots the set CPI more when moving fast than when moving slow.
Our Verdict
The Corsair KATAR PRO XT is decent for office use. While it doesn't have an ergonomic shape, this very well-built mouse should still feel very comfortable for most hand sizes using a claw or fingertip grip. Unfortunately, its scroll wheel doesn't have L/R tilt buttons, and it can't be unlocked for infinite scrolling. Also, the mouse isn't wireless, and some people might find the cable cumbersome.
- Feels very well-built.
- Customization software available on Windows and macOS.
- Two programmable side buttons.
- Not as ergonomic as dedicated office mice.
- Wired-only design.
- No free wheel or L/R tilt buttons.
The Corsair KATAR PRO XT is great for FPS gaming. It feels very well-built, and it's best suited for a claw or fingertip grip. Despite not having a honeycomb design, this mouse is quite light. The click latency is low, and it should feel responsive for most people. Unfortunately, its sensor is very inconsistent, and it undershoots the set CPI when moving fast more than when moving slow.
- Feels very well-built.
- Customization software available on Windows and macOS.
- Low click latency.
- CPI can be adjusted in increments of one.
- Sensor is inconsistent between fast and slow movements.
The Corsair KATAR PRO XT is very good for MMO gaming, although it doesn't have nearly as many side buttons as dedicated MMO mice. It has a low click latency and a wide CPI range that can be adjusted very precisely in increments of 1. It feels very well-built and comfortable, but people with larger hands may struggle with a palm grip. Unfortunately, its sensor is very inconsistent, and it undershoots the set CPI more when moving fast more than when moving slow.
- Feels very well-built.
- Customization software available on Windows and macOS.
- Low click latency.
- CPI can be adjusted in increments of one.
- Doesn't have as many buttons as dedicated MMO mice.

The Corsair KATAR PRO XT is a great ultra-light gaming mouse. It's quite lightweight, feels very well-built, and is suitable for most hand sizes using a claw or fingertip grip. It has a low click latency and a high maximum polling rate. The paracord-like cable is fairly flexible, although it does retain some kinks.
- Feels very well-built.
- Low click latency.
- Quite light.
- CPI can be adjusted in increments of one.
- Sensor is inconsistent between fast and slow movements.
The Corsair KATAR PRO XT isn't designed for travel. This wired mouse won't be ideal while working in tight spaces like a bus or plane, and it isn't very portable.
- Feels very well-built.
- Wired-only design.
- Bulky design may not fit in all laptop cases.

Popular Mouse Comparisons
The Corsair KATAR PRO XT is a great gaming mouse that's quite light, although it isn't as light as some dedicated ultra-light gaming mice. It has a very wide CPI range that, unlike many other gaming mice, you can adjust very precisely by increments of 1. Unfortunately, the sensor is a bit inconsistent as it tends to undershoot the set CPI more when moving the mouse fast than when moving it slowly. For other options, see our recommendations for the best gaming mouse, the best FPS mouse, and the best wired mouse.
The Corsair KATAR PRO XT is better than the Corsair KATAR PRO Wireless, but the PRO Wireless is a better choice if you prefer not having a cord. Otherwise, the PRO XT has a wider CPI range that can be adjusted very precisely in increments of 1, and it has a significantly lower minimum lift-off distance. On the other hand, the PRO Wireless' sensor has zero CPI variation, and its click latency is much lower despite being wireless.
The Razer Viper Mini and the Corsair KATAR PRO XT are both ambidextrous, wired gaming mice. The Razer is a better choice if you prefer having an ultra-light mouse since it weighs quite a bit less than the Corsair. The Razer also has a much lower click latency, many more programmable buttons, and smoother-gliding feet. However, the Corsair has a much lower lift-off distance, a more precisely adjustable CPI range, and its customization software is available on macOS.
The SteelSeries Rival 3 and the Corsair KATAR PRO XT are great wired gaming mice with a similar ambidextrous shape. The Corsair's paracord-like cable feels more flexible than the SteelSeries's rubber cable, but its mouse feet don't glide as well. The Corsair has a more precisely adjustable CPI range and a much lower list-off distance, but its sensor isn't as consistent as the SteelSeries's.
The Corsair KATAR PRO XT and the Logitech G203 Prodigy are both great gaming mice with a similar ambidextrous, egg-shaped design. The Corsair has a more flexible paracord-like cable and a much wider CPI range that can be adjusted very precisely in increments of 1. On the other hand, while the Logitech's CPI range isn't as wide or adjustable, its sensor is significantly more consistent. Also, it has more programmable inputs, and you can set a profile switching button. The click latency is also lower, although not by a significant amount.
