Dimension comparison
Design and Comfort
The ProtoArc EM11 NL Ergonomic Mouse offers a sophisticated ergonomic design that promotes comfort during extended use. Its extended wrist rest supports a natural hand position, potentially reducing the risk of strain injuries. In contrast, the Logitech M171 Wireless Mouse features a compact, ambidextrous shape designed for mobility, making it easy to carry in a bag. While the M171 is comfortable for casual use, it does not emphasise ergonomic features to the same extent as the ProtoArc. The choice here largely depends on whether you prioritise ergonomics for long usage or portability for on-the-go tasks.
Connectivity Options
The ProtoArc EM11 NL excels with its advanced connectivity, allowing users to connect up to three devices using both Bluetooth 5.0 and 2.4G USB options. This versatility is beneficial for individuals who frequently switch between devices, making it a convenient choice for multitaskers. The Logitech M171, however, employs a straightforward plug-and-play connection using a USB receiver, establishing a reliable link in just three seconds. For those who need to manage multiple devices seamlessly, the ProtoArc's dual connection modes are superior, while the Logitech may suffice for simpler setups.
Battery Life
Battery longevity varies significantly between the two models. The ProtoArc EM11 NL features a rechargeable 500mAh Li-ion battery, designed to conserve power by entering sleep mode after 30 minutes of inactivity. Users are notified to recharge when the indicator flashes red. The Logitech M171 boasts an impressive 12-month battery life on a single AA battery, along with automatic sleep features, making it a low-maintenance option. If you prefer a long-lasting battery without the need for frequent charging, the Logitech M171 has a clear advantage in this area.
DPI and Sensitivity
The ProtoArc EM11 NL offers adjustable DPI settings at 1000, 1600, and 2400, providing flexibility for users who require precision for tasks like graphic design or gaming. This high sensitivity can enhance tracking accuracy on various surfaces. Conversely, the Logitech M171 does not specify adjustable DPI settings but is designed for smooth and accurate cursor control on almost any surface. For users who need precise movements, the ProtoArc's adjustable DPI can be a deciding factor, while the M171 serves well for general use without the need for such specifications.
Compatibility
In terms of compatibility, the ProtoArc EM11 NL supports a wide range of operating systems, including Windows 8, Windows 10, Mac OS X (10.12 or higher), and Android (4.3 or higher). This broad compatibility ensures that users can seamlessly integrate the mouse with various devices. The Logitech M171 also claims extensive compatibility with Windows, macOS, Linux, Chrome OS, iPadOS, and Android. Both mice cater to a diverse user base, but if you specifically need compatibility with Mac systems, the ProtoArc may offer a slight edge due to its more explicit support for Mac OS.
Price Point
Pricing is a notable differentiator between the two products. The ProtoArc EM11 NL is priced at £18.69, reflecting its ergonomic design and advanced features. In comparison, the Logitech M171 is more budget-friendly, retailing at £13.99. While the ProtoArc justifies its higher price with ergonomic benefits and multi-device connectivity, the M171 offers solid performance and reliability at a lower cost. Consumers will need to consider whether the additional features of the ProtoArc justify the extra £4.70 for their specific needs.
User Experience
The ProtoArc EM11 NL is recommended for users with medium to small hands, ensuring a comfortable fit for its target demographic. However, some users might experience discomfort initially as they adapt to the ergonomic design. The Logitech M171, with its ambidextrous design, is universally comfortable and friendly for both left and right-handed users, appealing to a broader audience. If you have smaller hands and prioritise ergonomic support, the ProtoArc may be ideal. In contrast, the M171 is suitable for users looking for a universally accommodating mouse.
Which should you buy?
Choosing between the ProtoArc EM11 NL Ergonomic Mouse and the Logitech M171 Wireless Mouse largely depends on your individual needs and preferences. If you prioritise ergonomic design, advanced connectivity, and adjustable DPI settings for precision, the ProtoArc is the way to go. However, if you prefer a budget-friendly option with long battery life and solid compatibility across various operating systems, the Logitech M171 offers great value. Ultimately, consider how you plan to use the mouse and which features will enhance your experience the most.
