For a lefty searching for the best gaming mouse, this is a tough place to be. Though symmetrical in shape does not equate to true ambidextrousness, there are many excellent symmetrical gaming mice available, such as the Logitech G Pro X Superlight 2 and the Razer Cobra Pro. Although their shape allows left-handed users to theoretically use them, both of those mice are still intended for right-handed users because they only have thumb buttons on the left side.
Yet the most recent symmetrical mouse from Corsair is actually ambidextrous: The Corsair M75 has thumb buttons on both sides and can be used wirelessly or wiredly. The thumb buttons can be replaced with flat buttons, allowing you to avoid feeling the buttons when not in use. Both the wired and wireless Corsair M75 mice were provided by Corsair for review; however, due to their close resemblance, this review will mostly address the Corsair M75 Wireless model. The M75 is priced at $129.99 for the wireless version (which comes in both black and white) and $79.99 for the wired version (which comes in black only).
Corsair M75 Wireless
The Corsair M75 Wireless mouse has a symmetrical design and is genuinely ambidextrous, with movable thumb buttons on both sides. It has a smooth, light-weight plastic shell with two thin lighting stripes that taper down toward the bottom, where Corsair’s ship logo also illuminates. It comes in black and white.
With the thumb buttons elevated on the left side, the mouse is initially set up for use by the right hand. Four additional thumb buttons are included in the box; you can switch them out as needed. There are two raised buttons for the right side and two flat buttons for the left. Although Corsair refers to the button options as “raised” or “smooth, non-clickable buttons,” the flat buttons are actually very clickable and function as intended even after being switched in. They are flat and flush with the mouse’s surface.
Of course, Corsair’s iCue peripheral software allows you to disable them.
There’s a toggle to turn off the left-side and right-side buttons, respectively, when in right-handed mode. There’s also a toggle to turn on all buttons, but you’ll have to manually turn off the side buttons if you want to. However, in case you were wondering if replacing the flat buttons would somehow stop those side buttons from working, the answer is no. Unlike some mice with swappable buttons (like the Glorious Model I 2 Wireless), these are not button deletes.
The side buttons are simple to replace and are magnetic. No tools are required; all you need to do is press the button’s interior until it pops out.
Corsair M75 Air
At 5.04 inches (128 mm) in length, 2.56 inches (64.6 mm) in width, and 1.64 inches (42 mm) in height at its thickest point, the M75 Wireless is a rather large mouse. Its shape is rather generic, tapering toward the front and slightly curved for grip. With a weight of 3.14 oz (89 g), the Corsair M75 Wireless is a bit too bulky to be categorized as an ultra-lightweight mouse (the wired model weighs 2.61 oz, or 74 g). The Corsair M75 Air, which weighs 2.12 oz (60 g) and resembles the Corsair M75 Wireless in appearance, is another extremely light mouse offered by Corsair; however, it lacks the thumb buttons on the right for lefties.
If you count the clickable scroll wheel, the mouse has nine buttons, six of which can be programmed. Although Corsair doesn’t let you reprogram the primary click the left button in right-handed mode and the right button in left-handed mode technically, seven of them are programmable. Although it’s a little stiffer than he would like, the notched and sturdy scroll wheel didn’t bother me too much during my testing.
A PTFE strip encircling the sensor and two sizable PTFE strips along the top and bottom edges are located on the mouse’s underside. There are two triangle buttons on either side of the sensor: one for power and toggling between Bluetooth and 2.4GHz wireless, and another for switching between DPI steps that can be adjusted in iCue. Additionally, and always a nice touch, there’s a hollowed-out storage area for the mouse’s 2.4GHz wireless USB-A dongle.
The M75 Wireless comes with an extra set of buttons, a 2.4GHz wireless dongle, and a 6-foot (1.8-meter) braided USB-C to USB-A cable for charging. The cable is of a respectable quality, but it’s not as ultra-flexible as some companies’ (like Razer’s “SpeedFlex” cables) low-drag cables; if you use the M75 Wireless while charging, cable drag will occur. Though it’s not too severe, you will undoubtedly feel it. The cable that comes with the wired Corsair M75 is also quite stiff; if you want a wired mouse that is lightweight and doesn’t drag, he suggest the HyperX Pulsefire Haste 2.
M75 Corsair
The Corsair Marksman 26K optical sensor, featured in the Corsair M75 Wireless, has a maximum sensitivity of 26,000 DPI, a maximum speed of 650 IPS, and the ability to withstand accelerations of up to 50 G’s. With no lag between the buttons and their switches, it features optical left- and right-click switches that allow for quick, forceful clicks. The buttons are a little noisy, but they provide a good amount of tactile feedback and clickiness without being overly rigid.
The Corsair M75 Wireless performed as expected: He had no problems with lag, connectivity, or latency, and the mouse felt accurate and responsive all the time, even when it was running low on batteries or waking up from sleep. Its sensor tracked on a variety of surfaces, including wood, paper, carpet, concrete, and different mouse pads, including a glass mouse pad.
Although it is not the lightest mouse available, its pure PTFE feet and relatively light weight allow it to glide smoothly over most surfaces. Its slightly tapered shape prevented it from slipping through my fingers, so he had no trouble flicking or swiping quickly. However, it is still noticeably heavier than mice that are incredibly light, like the Logitech G Pro X Superlight 2. Despite its somewhat generic-looking shape, the mouse is overall very comfortable, and most gamers won’t likely find the slightly heavier weight to be an issue if they don’t plan on picking it up too often.
Although the Corsair M75 Wireless boasts four programmable side buttons, you’ll probably only use two of them frequently. He can only presume that the right-side buttons are similarly positioned and simple to click as the left-side buttons (he use my right hand) are. As previously mentioned, you will inadvertently press the buttons if they are activated, even though the flat buttons you can swap in don’t truly stop the buttons from functioning. But since they’re disabled by default the left buttons by default if you’re using the mouse with your left hand; the right buttons by default this shouldn’t be too big of a problem.
M75 Wireless’s Software and Features
With Corsair’s iCue software, the Corsair M75 Wireless can be customized. Six programmable buttons on the mouse are programmable with iCue: the scroll wheel click, all four thumb buttons, and the right mouse button (or left mouse button in left-handed mode). Additionally, you can adjust the RGB lighting and DPI steps of the mouse, as well as the key assignments and lighting for the mouse’s single onboard profile.
Additionally, iCue has a Device Settings menu where you can modify the RGB lighting brightness of the mouse, enable all side buttons or switch to left-handed mode, and tweak other settings like angle snapping and button response optimization in addition to raising or lowering the lift-off height. The polling rate of the mouse is fixed at “up to” 2,000 Hz using Corsair’s “Slipstream” wireless polling rate, which cannot be changed.
The Corsair M75 Wireless features two distinct RGB lighting zones: the underglow, which runs along the mouse’s back edge, and the logo and two stripes along its side. He don’t think this is the best way to use RGB since it prevents the beautiful color blending between zones that you can see on the Logitech G502 X Plus.
Each zone can be programmed separately, and there isn’t much interaction between them. This underglow section is so boring that he his not sure why it’s even here. Although you get some underglow when you turn the RGB lighting brightness up to 100%, it’s not nearly as bright or vibrant as what you’ll get from something like Razer’s Cobra Pro.
The M75 Wireless’s wireless experience and battery life
Three types of connectivity are available with the Corsair M75 Wireless: Bluetooth, wired (through USB-C), and low-latency 2.4GHz wireless. “Slipstream” is the name Corsair gives to its 2.4GHz wireless technology, which it claims can poll at up to 2,000 Hz, cutting down on latency from 1 ms to 0.5 ms for a 1,000 Hz polling rate. Most players won’t notice this difference, but in first-person shooter games, where speed is crucial, it may be significant. (Of course, compared to most FPS-focused mice, the M75 Wireless is a little heavier.)
The Corsair M75 Wireless’s maximum polling rate is 2,000 Hz, while the wired mouse’s is 8,000 Hz. While most gamers may not notice, an 8,000 Hz polling rate reduces latency to 0.125 ms
With the RGB lighting off, Corsair estimates that the Corsair M75 Wireless will last 105 hours on 2.4GHz wireless, which is about what he would anticipate from a mouse this size and weight. In comparison, the M75 Wireless boasts 65 hours of battery life when the lighting is turned on (we’ll assume that’s at 50% brightness, not 100%), while the 80g Logitech G Pro Wireless, which also has both left and right thumb buttons, only manages 60 hours.
In summary
Left-handed gamers may prefer Corsair’s M75 Wireless, the only mouse with thumb buttons. A reliable, lightweight gaming mouse with a symmetrical shape that looks generic but is surprisingly comfortable, a decent battery life, and a 2,000 Hz polling rate great features but nothing special
Symmetrical mice are plentiful, but right-side thumb buttons are rare. Only the Logitech G Pro Wireless, the outdated Razer Viper, and the wired and wireless Corsair M75 are available.
