Buying a Corsair M55 gaming mouse: what should you consider before ordering?

A gaming mouse may seem simple at first glance: plug it in, set the DPI and start playing. Yet many PC users buy a model that feels less suitable for their playing style after just a few weeks. Sensitivity that is too high can make precise aiming difficult, a flat battery can interrupt an online session and a wireless mouse does not always work in the way you expect.

The Corsair M55 gaming mouse is designed for right-handed gamers and users who want flexibility. The model supports 2.4GHz RF wireless, Bluetooth and USB Type-A. According to the product specifications, it also features an optical sensor with up to 24,000 DPI, six programmable buttons and a weight of 85 grams without the battery. Below, we explain which features you should really check and what type of user this mouse is suited to.

Three gaming mouse buying pitfalls

1. Looking only at the maximum DPI figure

A gaming mouse with 24,000 DPI sounds impressive, but a high maximum DPI is not automatically necessary. DPI determines how far the cursor moves with the same hand movement. For everyday use and many games, players often choose a lower setting. What matters more is that the sensor supports multiple speeds and that you can adjust them easily.

The Corsair M55 offers multiple DPI speed settings. This makes the mouse suitable for both fast movements and more precise aiming. Treat the maximum value primarily as part of the specification, rather than a guarantee of better performance.

2. Confusing “wireless” with a single connection type

A wireless gaming mouse can work via a USB receiver or Bluetooth. These are different connection methods. A 2.4GHz receiver is practical for a dedicated gaming PC, while Bluetooth can be useful for a laptop or a device without a spare USB port.

The Corsair M55 wireless mouse supports both options. Using the included USB receiver, you get an RF connection with a stated range of up to 10 metres. For productivity on the go, Bluetooth may be a practical choice. However, check in advance whether your computer supports Bluetooth and whether you would prefer to use a USB receiver when gaming.

3. Failing to factor battery use into your comparison

The Corsair M55 uses one replaceable AA battery. According to the product specifications, the battery is not rechargeable and is not included. This keeps the initial purchase price down, but it does mean that you will need to buy a spare battery yourself. The mouse has a battery indicator, allowing you to monitor the battery level.

If you are specifically looking for a rechargeable gaming mouse, you may be better off with another model. The M55 can also be used via the USB cable, but check what usage mode you want when ordering and whether the cable is long enough for your setup.

Key specifications explained

Optical sensor and 24,000 DPI

The Corsair M55 is an optical gaming mouse with an adjustable tracking resolution of up to 24,000 DPI. An optical sensor uses light to detect movement across a surface. For best results, use the mouse on an even, suitable desk surface or a mouse mat. The product specifications do not state that the mouse works on glass, so do not assume that it does.

For competitive gaming, stable tracking is more important than simply having the highest DPI figure. For example, set a lower DPI for shooters and a higher setting for navigation or large screens. You can further adjust the settings through Corsair iCUE, provided that your operating system and software version are supported.

Six programmable buttons

The mouse has six programmable buttons. This is useful when you want to keep shortcuts, browser functions or in-game commands within easy reach. Consider your grip and the position of your index finger and thumb beforehand. More buttons are not always more convenient if you frequently press a side button by accident.

For productivity, the extra buttons could be assigned to functions such as going back, going forwards or activating a frequently used shortcut. In games, their usefulness depends on the genre and your personal layout.

Connections and compatibility

According to the product information, the Corsair M55 works with Windows and macOS. You can choose from:

  • 2.4GHz RF wireless via a USB receiver;
  • Bluetooth for compatible laptops and PCs;
  • USB Type-A via the included 1.8-metre cable.

The cable is useful when the battery is flat or when you want to use a wired connection. Check that your computer has a USB Type-A port. If your laptop only has USB-C, you may need a suitable adapter; this is not listed as an included accessory.
