Buying a wireless mouse: what matters for ergonomics, connectivity and precision

A wireless mouse can keep your desk tidier and make it easier to switch between a laptop, PC and Mac. However, wireless mice vary considerably in connectivity, sensor, button layout and power supply. A high DPI figure alone, for example, says little about how practical a mouse is for everyday use.

Before buying, you should pay particular attention to three common pitfalls:

  • Unclear connectivity details: “Wireless” can mean Bluetooth, 2.4 GHz wireless, a proprietary receiver or a combination of these. Not every laptop has Bluetooth, and not every USB receiver can be plugged directly into modern devices with a USB-C port.
  • Exaggerated DPI figures: A mouse with a high DPI setting can be moved very quickly. For office work or image editing, however, a lower setting may be easier to control precisely. Sensor quality, tracking performance and the ability to adjust sensitivity are more important.
  • Unsuitable shape and range: An ergonomic mouse needs to suit your hand size, grip and working hours. A large right-handed mouse is not automatically suitable for smaller hands or left-handed use.

The most important criteria for a wireless mouse

1. Connectivity: Bluetooth, wireless receiver or three operating modes

A Bluetooth mouse can usually be paired with compatible laptops, tablets or Macs without an additional receiver. This saves a USB port. For desktop PCs without Bluetooth, a 2.4 GHz receiver is practical instead. This connection is often established directly via a nano receiver.

A multi-device mouse can be paired with several devices. Check how many devices it supports and how switching between them works. On some models, a button on the underside is all that is needed; others offer software-assisted switching.

A mouse with three operating modes usually combines 2.4 GHz wireless, Bluetooth and USB-C wired operation. This is useful if you switch between gaming, working from home and several devices. Also check whether the configuration software is available for Windows and macOS. According to the product details, the software for the ET model is intended for Windows only and can only be used in wired mode.

2. Understanding sensors and DPI correctly

DPI describes how many pixels the mouse pointer moves across the screen for a given physical movement. Moderate settings are often sufficient for classic office tasks. Creative applications benefit from finely tuned sensitivity, while gamers should also consider polling rate, latency and smooth tracking.

A gaming mouse with 8,000, 24,000 or 44,000 DPI offers a wide adjustment range. However, this does not automatically mean greater precision in every situation. The following details are more relevant when choosing a mouse:

  • Sensor type: Optical sensors are widely used in gaming mice; depending on the model, laser sensors may also work on certain smooth surfaces.
  • Polling rate: Figures of up to 1,000 Hz or 8,000 Hz indicate how often the mouse reports its position to the computer. The actual effect also depends on the game, system and display.
  • Surface: Even a good sensor may respond differently on glass, highly reflective surfaces or dirty surfaces. According to the manufacturer, the Logitech MX Master 4 features an 8K DPI Darkfield laser sensor designed to work on glass with a minimum thickness of 4 mm.

3. Battery, charging and materials

A rechargeable mouse avoids the need to replace batteries regularly. Important factors include the stated battery life, charging port and whether you can continue working while the mouse is charging. USB-C is convenient, but check whether a charging cable is included.

The Logitech MX Master 4 is stated to offer up to 70 days of battery life; according to the product data, a one-minute charge should provide up to three hours of use. However, the supplied USB-C cable is not included with the variants mentioned. The Logitech G PRO X SUPERLIGHT 2 is specified with up to 95 hours of battery life and USB-C charging.

The usual safety rules apply to lithium-ion batteries: do not open them, do not expose them to excessive heat and only use suitable or certified charging sources. A mouse should also feel comfortable in your hand. Weight, width, thumb rest and button position are practical factors that product images alone cannot fully show.

Frequently asked questions about wireless mice

How do you connect a wireless mouse to a PC or Mac?

For Bluetooth models, open your computer’s Bluetooth settings and select the mouse to pair it. For 2.4 GHz models, plug in the USB receiver and switch on the mouse. If a device only has USB-C ports, you will need a suitable receiver or a mouse with a USB-C connection. Some models also support wired operation.

How long does the battery of a rechargeable mouse last?

Battery life depends on the sensor, lighting, polling rate and usage. Manufacturer claims such as “up to 50”, “70” or “95 hours”, or several weeks, are comparison figures measured under specific conditions. RGB lighting and high polling rates can increase power consumption. So also check whether the mouse can be used while charging.

Is a mouse with a high DPI automatically more precise?

No. DPI primarily refers to sensitivity. For precise work, smooth tracking, a suitable surface, a stable connection and finely adjustable software are important. Choose the DPI setting based on your screen resolution and personal working style, rather than simply choosing the highest advertised figure.
