The Corsair KATAR PRO Wireless is a good wireless gaming mouse. It's a well-built mouse that has an ambidextrous design with two buttons on its left side. It's small enough to fit into most laptop bags, and it has USB receiver storage within its battery compartment. It has an excellently low click latency and a wide CPI range that can be adjusted in increments of 100. Its smaller size is best suited for a fingertip grip, but small and medium-sized hands will find it comfortable with a palm and claw grip. If you prefer a wired design, the Corsair KATAR PRO XT has the same size and shape, and it performs better. We've heard some reports of Bluetooth connectivity issues with newer M1 Macs, but this isn't something we test for. Let us know in the discussions if you've had the same issues.

Compared To Other Mice
The Corsair KATAR PRO Wireless is a good wireless gaming mouse, especially for its price point. Its click latency is very low, and it has a wide CPI range, although the sensitivity can't be adjusted as precisely as other gaming mice on the market. Also, it's somewhat heavy for its size. For other options, check out our recommendations for the best wireless gaming mouse, the best FPS mouse, and the best Corsair mouse.
The Corsair KATAR PRO Wireless and the Logitech G305 LIGHTSPEED are both good gaming mice. The Logitech feels better built, its CPI range is wide, and you can adjust the set CPI more precisely. On the other hand, the Corsair’s click latency with its receiver is slightly lower, and it has Bluetooth support.
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 is better than the Corsair KATAR PRO Wireless. The Razer feels better built, has more programmable buttons, and has a lower lift-off distance than the Corsair. However, the Corsair has wireless capabilities, its sensor is more consistent, and the Corsair iCUE software has better compatibility.
The Logitech G603 LIGHTSPEED is better than the Corsair KATAR PRO Wireless. The Logitech feels better built and more comfortable. Its bigger size is better suited for a palm grip, while the Corsair is better for a fingertip grip. Also, the Logitech's CPI range is wider and more precisely adjustable. However, the Corsair's click latency is lower, and its sensor is more consistent.
The Corsair KATAR PRO Wireless is better than the Razer Atheris. The Corsair's slightly bigger size makes it useable with more grip types, and its CPI range is wider and more consistent. Its click latency is also much lower. On the other hand, the Razer is better for travel since it's smaller.
The Razer Viper Ultimate is a slightly better gaming mouse than the Corsair KATAR PRO Wireless. The Razer feels better built, has a wider and more adjustable CPI range, and more programmable buttons. However, the Corsair has Bluetooth support, uses one AA battery, and its software is compatible with macOS, although it's less user-friendly.
Test Results
The Corsair KATAR PRO Wireless is a low-profile mouse with an ambidextrous design and two side buttons on its left side. The sides are slightly textured to help with grip. Its body is matte black, but its side buttons, CPI buttons, and the area surrounding the scroll wheel are glossy. It has no lighting zones, except for the CPI switch which lights up green, red, or white to let you know which CPI you're set to, and blue when in Bluetooth pairing mode.
The Corsair KATAR PRO Wireless is very good for travel since it's small and wireless, meaning you don't need to worry about a cable. It should fit into most laptop cases, and it also has space in its battery compartment to store the receiver.
It has good build quality. Overall, its plastic feels solid and there are no squeaking sounds when pressing the buttons. However, there's a slight rattling that seems to come from the right clicker when it's shaken. The top back cover feels a little loose, and it has some flex when you lightly press down on it, but it isn't too noticeable while using the mouse.
The mouse feels comfortable. Although there aren't any grips, there's a slightly textured pattern on each side to help prevent slipping. The side buttons are well-placed, and all hand sizes should have no problem reaching them with a fingertip grip. Due to its small size, larger hands will struggle to use it with a palm grip and extra-large hands with a claw grip.
Due to the mouse's small size, people with large or extra-large hands might struggle to comfortably reach the scroll wheel and side buttons with a palm grip. Small and medium hands should feel comfortable with this grip.
Due to the mouse's small size, people with extra-large hands may feel this mouse is too small to be used with a claw grip. All other hand sizes should feel comfortable.
Any hand size should be comfortable using it with a fingertip grip.
The Corsair KATAR PRO Wireless has fantastic wireless connectivity options. It requires a single AA battery which Corsair claims lasts up to 135 hours, though we haven't tested this. The CPI switch light also indicates battery life when powering on. If you prefer a wired option, the Corsair KATAR PRO XT is nearly identical to the KATAR PRO Wireless but it performs better.
Note: We've heard some reports of Bluetooth connectivity issues with newer M1 Macs, but this isn't something we test for. Let us know in the discussions if you've had the same issues.
This is a wireless-only mouse that uses a battery, so it doesn't come with a cable.
The feet on the Corsair KATAR PRO Wireless are good. Despite having two sharp edges, the feet glide well both on a mousepad and directly on a desk.
It has a decent amount of buttons. All of the buttons are programmable through the iCUE software, except for the up and down scrolls.
It has excellent click latency. It's a little higher over Bluetooth, but it should still be low enough to feel responsive while gaming.
While the Corsair KATAR PRO Wireless has a wide CPI range, the sensitivity can only be set in increments of 100, which isn't as precise as some other options. The sensor is very consistent, and it doesn't tend to undershoot the set CPI by much. You can choose between four polling rates: 125Hz, 250Hz, 500Hz, and 1000Hz. Unfortunately, its lift-off distance is quite high, so the sensor might track your movement when repositioning your mouse.
The scroll wheel is a textured rubber that feels grippy, and the steps are pronounced. There's no L/R tilt and it can't be unlocked for infinite scrolling.
The Corsair KATAR PRO Wireless is quiet and shouldn't bother those around you.
The Corsair KATAR PRO Wireless has outstanding companion software. The Corsair iCUE is compatible with both Windows and macOS, and you can customize every aspect of the mouse. However, the task of assigning macros and saving to the on-board memory isn't very user-friendly.
