Dimension comparison
Design and Comfort
The Logitech M240 Silent Bluetooth Mouse boasts a compact and travel-friendly design, while the ProtoArc EM11 NL Ergonomic Mouse prioritises ergonomic comfort. The M240 is small enough to fit comfortably into a bag, making it an ideal choice for those who are always on the go. On the other hand, the ProtoArc EM11 features an extended wrist rest that supports a natural hand position, alleviating strain during extended use. This ergonomic design is especially beneficial for users who spend lengthy hours working at a desk, as it promotes a relaxed position for the forearm and wrist, reducing muscle tension.
Connectivity Options
When it comes to connectivity, the ProtoArc EM11 excels with its ability to connect up to three devices simultaneously through both Bluetooth 5.0 and 2.4G USB modes. This feature allows for seamless switching between devices, enhancing user convenience. In contrast, the Logitech M240 utilises a straightforward Bluetooth connection, which, while reliable, does not offer multi-device capabilities. The flexibility offered by the ProtoArc EM11 makes it a preferable option for users who operate multiple devices at once.
Battery Life
Battery life is a critical factor in choosing a wireless mouse, and here the Logitech M240 stands out with an impressive battery life of up to 18 months. This extensive duration is supported by an energy-efficient auto sleep feature, allowing users to go longer without needing to change batteries. Conversely, the ProtoArc EM11 is equipped with a rechargeable 500mAh Li-ion battery, which can be charged via a Type-C cable. Though it does not specify a usage duration, it does feature a low battery indicator that alerts users when charging is necessary. For those prioritising longevity, the Logitech M240 is the more appealing choice.
Noise Levels
In terms of noise levels, the Logitech M240 is designed to create less disturbance during use. With a 90% reduction in click sound, it provides a quieter working environment, making it an excellent option for shared spaces or quiet settings. The ProtoArc EM11, while also featuring a whisper-quiet click, does not specifically quantify its noise reduction capabilities. For users who are sensitive to sound or work in noise-sensitive environments, the Logitech M240’s superior noise reduction makes it a clear winner.
Compatibility
Both mice offer broad compatibility across various operating systems, but the Logitech M240 has an edge with its extensive platform support. It works seamlessly with Windows, macOS, Linux, ChromeOS, iPadOS, and Android, and is certified to work with Chromebook devices. The ProtoArc EM11 also supports multiple platforms, including Windows and Mac OS, but it is limited to specific versions and does not provide the same level of universal compatibility. For users who utilise different operating systems, the Logitech M240 provides greater versatility.
Price Point
In terms of pricing, the Logitech M240 is currently available for £14.99, making it the more affordable option of the two. The ProtoArc EM11, priced at £18.69, offers additional features like ergonomic design and multi-device connectivity, which may justify the higher price for some users. However, for those looking for a reliable and quieter mouse at a lower cost, the Logitech M240 is undoubtedly the more budget-friendly choice.
User Experience
User experience can greatly influence the choice between these two mice. The Logitech M240 is praised for its ease of use, with a simple plug-and-play Bluetooth setup that connects in seconds. Its compact build is designed for portability, making it suitable for a range of users, from students to professionals. The ProtoArc EM11, aimed at those who require a more ergonomic option, may take some getting used to, especially for first-time users of vertical mice. While it provides enhanced comfort, some users may need time to adjust to its unique design.
Which should you buy?
Choosing between the Logitech M240 Silent Bluetooth Mouse and the ProtoArc EM11 NL Ergonomic Mouse ultimately depends on individual needs. If you prioritise a quiet, portable, and budget-friendly option, the Logitech M240 is the way to go with its extended battery life and broad compatibility. However, if ergonomic comfort and the ability to connect to multiple devices are more significant for your workflow, the ProtoArc EM11 may be worth the extra cost. Assess your primary requirements, and you’ll find the right fit for your computing needs.
