What We Think

Previously, we liked what Corsair was doing with its products, but with the release of Corsair Ironclaw wireless, we were genuinely impressed. If we talk about the comfort level, this mouse easily wins the game. It has a more robust and sturdy build and comes with a palm grip. 

Thanks to the wireless aspect, the mouse won’t bother you with any dangling wires apart from recharging every 50 hours. The mouse is made for right-handers, and you’ll know why when we dive into the design, but Corsair Ironclaw wireless does an impressive job for what is advertised.


Here are some features of the Corsair Ironclaw wireless to help you get a better idea of what you’ll be getting.

Technical Specifications

The Corsair Ironclaw wireless has flawless connectivity, all thanks to the hyper-fast, sub-1ms 2.4GHz SLIPSTREAM. It also has 4.2 Bluetooth + LE and a USA Type-A USB port for wired connections. In addition, it has an impressive endurance of 50 million clicks and 3 RGB LED zones.

The optical sensor is the Pixart PMW3391 with 100-18,000 DPI sensitivity. The maximum speed of the sensor goes up to 400 IPS. The polling rate can go from 125 Hz to 1000 Hz. Moreover, the 2.4 Hz band allows you to charge your mouse while playing if connected via Bluetooth or USB to the PC.

The battery lasts about 16 hours if you use it with standard lighting, or up to 50 hours if used without any backlights. If we talk about the weight and size, the Corsair Ironclaw wireless is 5.5 x 3 x 1.6 inches, weighs about 130 grams, and has a right-handed design.


Apart from comfort, the Corsair Ironclaw wireless comes with 18,000 DPI sensitivity and a 400 IPS tracking speed. This ensures maximum precision and a fast pointer that you can adjust as per your preferences. The polling rate goes up to 1000 Hz, which can be seen in the performance. The Bluetooth also works well, and we didn’t face any lags during use.

The Slipstream technology that the Corsair Ironclaw wireless comes with ensures seamless connectivity without any lag, thanks to this top-tier feature. Apart from this, the optical technology detects the mouse’s movements regarding the surface beneath it to give you fair accuracy and overall performance.

The Corsair Ironclaw wireless is compatible with Windows and is designed for First-person Shooting (FPS) and Multiplayer Online Battle Arena (MOBA) game genres. The 18,000 DPI sensitivity again aids in accuracy and precision during the game. The mouse also comes with ten programmable buttons, offering various functionalities that you can customize to suit the game you are playing.  


Corsair Ironclaw Wireless MouseThe design and its grip were the first things that impressed us. The Corsair Ironclaw wireless feels sturdy and comfortable in your hand. The palm grip lets your hand sit and relax on the body. The button placement is also well within reach, making the experience flawless.

  • Size 

The Corsair Ironclaw wireless is undoubtedly a bit heavier, but with good reason. The 50-hour battery has made this model somewhat chunky, but on the plus side, it’s probably one of the best if you have larger hands or are looking for something with some extra room. You also get an impressive battery life, especially if you don’t use it with the backlight!

  • Form and Feel

The Corsair Ironclaw wireless has a soft-touch matte body. The contoured shape and the button placement optimize comfort and help your palm rest without hindering your game performance. The thumb grip on the side is finished with a rubber finish that ensures a good grip without causing too much friction. We liked the overall finish of the mouse, including the buttons that were robust but easy to click. The same goes for the scroll wheel.

  • Programmable Buttons

The left side of the mouse has five buttons, two of which are macro similar to the original Corsair Ironclaw. The third button is a bumper button that has three DPI settings. Many more programmable buttons are convenient once you learn to customize them according to your preferences.

Two CPI switches allow you to switch between three CPI settings—the two standard buttons behind the scroll wheel and the scroll wheel itself use a 50 million click rate. You can set up as many profiles as you want, and that’s another advantage of programmable buttons.

  • Lighting Zones 

If we talk about the lighting zones, the Corsair Ironclaw wireless comes with three, all of which are customizable. First, you get a Corsair logo at the back. Next up, we have a light below the scroll wheel and a set of three indicators on the left. The three lights show the DPI preset and give you information about the wireless connectivity. You can customize the RGB colors with the iCUE software. The Corsair Ironclaw wireless weighs 130 grams and is 126 mm long. Most people will take this as a chunky mouse, and it is. However, the design and the curves ensure that the hand conveniently reaches all the buttons and feels supported.


Once you have installed the iCUE software, you can get started with the customization. Customizing the lighting is a no-brainer, but you might need to spend some time programming the buttons. Since you get access to the iCUE software when you buy the Corsair Ironclaw wireless, you can sync all of your peripherals as well.

We specifically enjoyed creating and switching between all the different profiles on iCUE for various games. Not only this, but every profile you create is saved in the mouse itself, and you can access it even if you don’t have the iCUE software at any point.


Corsair Ironclaw Wireless MouseCorsair Ironclaw wireless’ performance is as flawless as it gets. There were no connectivity issues thanks to its slipstream technology. The optical sensor was also smooth and glided across multiple surfaces quite effortlessly. We also liked that the buttons were fast and consistent. There was no lagging whatsoever, which is a huge win if we compare it with other mice in the same price range on the market.

The Pixart PMW3391 optical sensor is a higher-end sensor that goes from 100 CPI to 18,000 CPI. You can, of course, change this to suit your preferences. The refresh rate was also notable and went from 125 Hz to 1000 Hz. All of this has made the Corsair Ironclaw wireless quite similar to more higher-end mice.

The battery claims to last 50 hours, and it does when you use the mouse without any backlight. If you use the standard light options, you can squeeze in a good 16 hours or even 24 hours with a few tweaks. But if you want to maximize the period, you will have to give up the lighting.

A thing that we love about the Corsair Ironclaw wireless is that you can charge it while playing your game. With most mice, you have to wait for it to charge before you start playing. But with the Corsair Ironclaw wireless, you get a micro USB so you can keep playing while the mouse is charging.

Is the Corsair Ironclaw Wireless Worth It? 

From all the mice we have tried during the past few months, the Corsair Ironclaw wireless is our favorite. The wireless connectivity is unmatchable. The build is robust and comfortable for most hand shapes, not to mention the customizable buttons that have been a huge game-changer.

Considering the price range, the Corsair Ironclaw wireless is a good deal. It has a fantastic battery life, and if you minimize other features like lighting, you can easily get the maximum without compromising the performance. Although the mouse doesn’t have wireless charging, you can still play while charging without affecting the performance.

Another thing most people will find great about this mouse is the Bluetooth connectivity. The Corsair Ironclaw wireless comes with Bluetooth 4 + LT that gives a flawless connection and doesn’t cause any lagging whatsoever.

The design and shape are something that can vary from one person to another. We read up on past clients’ reviews to see what people think about the shape. The general consensus was that this mouse is definitely on the chunkier side, but most people, including us, seem to enjoy that. It feels solid and sturdy in your hands. Despite being a heavy, larger mouse, the design gives your hands enough support, and the buttons are well within reach. 

Apart from this, the exterior of the Corsair Ironclaw wireless also seems high-end, just like most of its features. The soft-touch matte-black is a dream of many, especially when it comes with robust yet soft buttons. We also appreciated the scroll wheel, but some people think it could be better as it was a little heavy.

Overall, after comparing the Corsair Ironclaw wireless with others on the market, it is safe to say that this purchase won’t disappoint you. It is still missing one or two significant features like wireless charging, but we can easily let it go for the price. Apart from that, the Corsair Ironclaw wireless features are pretty high-end and well worth your money.


1. Is an optical sensor better than a laser sensor?

The main difference between laser and optical sensors is how they perform on different surfaces. A laser mouse can work on almost any surface as it can penetrate through the material. An optical sensor, on the other hand, works on selection. As a result, the performance between the two varies greatly.

A laser sensor usually has a low DPI rating and may be a tad jittery. An optical sensor, however, has high sensitivity thanks to its high DPI rating. So, an optical mouse sensor will give you better accuracy and tracking when compared with a laser sensor mouse.

Apart from this, an optical sensor will have a better consistency as there are no random movements or jitters. A laser sensor picks up all the useless curves, crevices, details, and movements on the surface, resulting in an inconsistent performance. 

So, if you are looking for a smooth and seamless gaming experience, a mouse with an optical sensor might be a better choice. However, if you think you can manage the inconsistency by optimizing a flat surface, then a laser sensor mouse can work equally as well.

2. What difference does DPI make for your mouse?

DPI (Dots per inch) measures how sensitive a mouse is. If your mouse has a higher DPI rating, the performance will be more accurate. This means that the mouse will pick up more details and detect smaller movements. However, a super high DPI rating isn’t always good. Sometimes, it can make your cursor super fast, hence hindering your game performance.

For this reason, most mice come with a variable DPI rating, so you can adjust it according to what you are doing. For instance, the Corsair Ironclaw wireless can go from 100 DPI to 18,000 DPI, which is great for multiple purposes. 

3. Why is a variable polling rate important?

The polling rate is the measure of the time your mouse reports to the computer. The higher the polling rate, the more inputs will be taken by the mouse from the computer. This also means less lagging and fast or consistent responses.

When we talked about the DPI rating, we saw that, at times, a low rating might be more helpful. However, in the case of the polling rate, the higher it is, the better.

An excellent quality mouse usually comes with a variable polling rate ranging between 125 to 1000 Hz. A setting above 125 Hz to 500 Hz is good, but if you have a good CPU, you can go up to a 1000 Hz rating. However, the difference between a 500 Hz rating and a 1000 Hz rating isn’t too drastic.


If you are looking for a practical gaming mouse with top-tier features, good battery life, and optimum comfort, the Corsair Ironclaw wireless might be the best choice for you.

But before you head on to buying anything, make sure you have done your research. Make a draft of what and how you’ll be using the mouse. Then take a closer look at the design and specs. Once you have done that, make sure you read the customer reviews and experiences to get a better idea of what you’ll be getting.
