Dimension comparison
Design and Comfort
The Logitech M705 Marathon Wireless Mouse is designed for comfort with an ergonomic shape that fits naturally in your hand, while the ProtoArc EM11 NL Ergonomic Mouse takes comfort a step further with an extended wrist rest. The M705’s sculpted design ensures that controls are easily within reach, making it a great choice for extended use. Conversely, the ProtoArc’s design is specifically made to promote a more natural wrist position, reducing muscle tension and minimising the risk of injury from repetitive strain. This ergonomic focus makes it particularly suitable for users who spend long hours at the computer.
Connectivity Options
The connectivity features of these mice differ significantly. The Logitech M705 employs a tiny unifying receiver that allows you to connect up to six devices, creating a clutter-free workspace. It is compatible with various operating systems, including Windows and Mac. On the other hand, the ProtoArc EM11 offers dual connection modes with Bluetooth 5.0 and 2.4G USB, enabling it to connect to three devices simultaneously. This versatility makes switching between devices effortless, although it does not support RGB lighting. Users can appreciate the flexibility of the ProtoArc, especially if they utilise multiple devices.
Battery Life
Battery life is a standout feature of the Logitech M705, boasting an impressive three-year lifespan. This means you can use the mouse extensively without the hassle of frequent battery replacements. In comparison, the ProtoArc EM11 has a rechargeable 500mAh battery, which can be charged via a Type-C cable. While it does not specify the exact duration of use before needing a charge, it does have an energy-saving sleep mode that activates after 30 minutes of inactivity. Thus, if longevity is a priority, the M705 clearly holds the advantage in this category.
Sensitivity and Control
The Logitech M705 offers click-to-click scrolling, allowing for precise navigation through lists and documents, while also featuring forward and back thumb buttons for added productivity. The ProtoArc EM11, however, provides adjustable DPI settings of 1000, 1600, and 2400, which are higher than conventional optical mice and enable more precise optical tracking. This feature can be particularly beneficial for users who need enhanced sensitivity for design or gaming tasks. The whisper-quiet clicks of the ProtoArc also cater to those who prefer a quieter working environment, while the M705 focuses more on functionality.
Target Audience
The Logitech M705 is targeted towards users who value comfort and long-lasting battery life, making it suitable for professionals and casual users alike. Its ergonomic design and universal compatibility make it a versatile option. In contrast, the ProtoArc EM11 is specifically recommended for users with medium to small hands, as its design caters to a more niche audience. This mouse is ideal for individuals who are particularly concerned about wrist strain and prefer a more relaxed position while using their computer.
Aesthetics and Build Quality
In terms of aesthetics, the Logitech M705 presents a classic look that aligns with Logitech’s well-established branding, which appeals to a broad audience. The build quality feels robust and dependable. The ProtoArc EM11, meanwhile, has a more modern ergonomic design but is noted for its lack of RGB lighting, which may appeal less to gamers or those who prefer a more vibrant aesthetic. However, both mice are built for durability, with each focusing on providing a quality user experience rather than flashy designs.
Price Comparison
The Logitech M705 is priced at £22.99, while the ProtoArc EM11 is slightly more affordable at £18.69. Despite the price difference, both products offer features that justify their costs. The M705’s three-year battery life and extensive connectivity options offer value for users looking for longevity and flexibility. Meanwhile, the ProtoArc EM11’s ergonomic design and dual connectivity make it an appealing choice for those seeking comfort at a lower price point. Ultimately, the decision may come down to individual budget and feature preferences.
Which should you buy?
Choosing between the Logitech M705 Marathon Wireless Mouse and the ProtoArc EM11 NL Ergonomic Mouse ultimately depends on your personal needs and usage patterns. If you value a long battery life, extensive device connectivity, and a comfortable, classic design, the Logitech M705 is the superior choice. However, if you're seeking an ergonomic design that prioritises wrist comfort and the ability to connect to multiple devices seamlessly, the ProtoArc EM11 is an excellent alternative that is also more budget-friendly. Both mice cater to different preferences, ensuring that there is an option for a wide range of users.
