Corsair M55 Wireless review: entry-level device with battery operation

Corsair, one of the best-known manufacturers of gaming peripherals, is launching a new wireless mouse on the market. The M55 Wireless has a symmetrical shape and uses Corsair’s low-latency Slipstream technology. As the mouse is intended as an entry-level device, it does not have a battery. You can read more about this in our test.

Design and processing

If you look at the portfolio of gaming mice, you can definitely see similarities to Corsair’s general design idea. Plain, simple housing in black with the typical triangles on the thumb rest. The case itself is in matt black, while the three extra keys are in high-gloss. The Corsair logo on the palm rest area in silver is an eye-catcher.

Two of the extra keys are located on the left-hand side. There are none on the right side, despite the symmetrical, ambidextrous shape. The third additional button is located behind the clickable mouse wheel. In the standard settings, this is intended for switching DPI, but each button can be freely configured. The compartment for the AA battery is also located on the top.

On the underside, we find two large PTFE sliding pads and a slot for the USB receiver. Next to the sensor is a switch that can be used to turn the mouse on or off. The button is also used to switch the reception mode. Corsair has thought about the M55 Wireless and it can be used with the receiver stowed away, as it fits in perfectly.

Features and battery life

Given the price, it is not surprising that this is an entry-level device from Corsair. Accordingly, not too much can be expected from the M55 Wireless in terms of features. Despite this, the technical details sound promising.

Unfortunately, the sensor in question is not specified. However, it delivers between 200 and 24,000 DPI and can be adjusted in 100 DPI steps. The tracking speed of 300 IPS (inches per second) and a maximum speed of up to 35 G at least suggests a higher-quality sensor.

Almost all available buttons can be freely configured via Corsair iCUE. Only the left mouse button cannot be configured to our liking. Both thumb buttons are easy to reach and, like all other buttons, have a pleasant and clear pressure point.

Corsair does not specify which switches are used for the keys. However, the Corsair M55 Wireless is advertised as having a lifespan of 60 million clicks. Just like the thumb buttons, the mouse buttons have a good pressure point. Compared to the Mountain Makalu Max(test), the volume of the key press is slightly louder. The scroll wheel is just as easy to turn and has a clearly perceptible grid.

Sensor and practical test

Corsair is definitely no stranger to the gaming market. Unfortunately, the M55 Wireless does not tell us which sensor has been installed. However, the mouse is very easy to use.

The wide DPI range (200 to 24,000 DPI) is advantageous for operation. We can move freely within this range and adapt the mouse to our needs. The sensor works precisely and reliably and did not let us down even in demanding situations.

The large PTFE gliding feet under the mouse also do their job. It does a particularly good job on fabric mouse pads. The AA battery takes some getting used to. Although the mouse is not heavy, a large part of the battery is at the back, which is noticeable. If you are coming from a wired mouse or one with a rechargeable battery, you will definitely have to get used to this.

Using Slipstream, 185 hours should be possible with an AA battery. With a Bluetooth connection, even 400 hours are possible.

Software

Corsair’s iCUE software has a lot of functions in addition to those that would be necessary for the M55 Wireless. The interface is logically structured and it is easy to see what needs to be customized.

You can customize all buttons except for the left click and assign your own function to them. There are basically no limits here. Whether keyboard keys, macros or changing the profile can be assigned to another key.

You can also choose where your profiles should be saved. You can decide for yourself whether they are saved in the iCUE software or directly on the mouse. The latter allows you to use the mouse with your settings on the go.

Conclusion

The Corsair M55 Wireless is a very interesting entry-level mouse on the market. As always with Corsair, the workmanship is very good. All gap dimensions fit and the USB receiver can be stowed perfectly in the mouse.

The mouse’s price makes it an entry-level device. This is partly due to the requirement of an AA battery. Although the mouse has a good battery life, the additional weight at the back is definitely noticeable.

However, Corsair makes up for this with the good features, such as Slipstream Wireless and the great customization options via the iCUE software.
