Price Comparison
The ProtoArc Ergonomic Wireless Keyboard Mouse is priced at £84.99, while the Logitech MK850 Multi-Device Wireless Keyboard and Mouse Combo is slightly more affordable at £72.99. The price difference of £12 indicates that the Logitech option may provide a more budget-friendly choice for users seeking a reliable wireless keyboard and mouse setup. Both products offer significant features that justify their price points, but if cost is a primary concern, the Logitech MK850 presents a compelling case.
Design and Ergonomics
Both products are designed with user comfort in mind, but they take different approaches. The ProtoArc Ergonomic Wireless Keyboard Mouse features a full-size ergonomic design with a curved and split keyframe, promoting a natural wrist posture. This design aims to reduce strain during extended typing sessions. In contrast, the Logitech MK850 offers a cushioned palm rest and a familiar deep-profile key layout, also focusing on comfort for all-day use. While both have their strengths, the ProtoArc's dedicated ergonomic focus may appeal more to those specifically looking to alleviate wrist discomfort.
Multi-Device Connectivity
The ProtoArc Ergonomic Wireless Keyboard Mouse supports connection to up to three devices simultaneously, allowing users to switch easily between them with a single button press. This feature is particularly beneficial for those who use multiple devices regularly. The Logitech MK850 offers similar functionality, enabling users to pair with up to three devices via Bluetooth or USB receiver. Both products excel in this area, but the ease of switching with the ProtoArc may be a deciding factor for users who frequently alternate between devices.
Mouse Performance
When it comes to mouse control, the ProtoArc Ergonomic Wireless Mouse boasts a DPI setting of 2000, providing precise control for various tasks. It also includes forward and backward buttons for added convenience during web browsing. The Logitech MK850 features a contoured design that fits comfortably in the hand and includes a hyper-fast scrolling wheel, enhancing productivity when navigating through documents or web pages. While both mice are designed for comfort and efficiency, the ProtoArc's higher DPI may be more attractive to users who require finer precision.
Battery Life and Charging
The ProtoArc Ergonomic Wireless Keyboard Mouse has built-in 500mAh lithium batteries that are rechargeable via a Type-C cable, with an auto sleep mode that activates after 30 minutes of inactivity, conserving battery life. On the other hand, the Logitech MK850 operates on two AAA batteries with an impressive three-year lifespan, reducing the need for frequent battery replacements. Users who prefer a rechargeable option may lean towards the ProtoArc, while those who appreciate the longevity of disposable batteries might favour the Logitech MK850.
Software and Customisation
Both products offer opportunities for customisation, although the extent varies. The Logitech MK850 stands out with its Logitech Options software, allowing users to assign up to 12 keys and buttons for shortcuts, enhancing productivity. This feature is particularly useful for power users who rely on specific functions during their workflow. The ProtoArc, while ergonomic and functional, does not mention any software for customisation, making the Logitech a more versatile option for users who value tailored functionality.
Compatibility
The ProtoArc Ergonomic Wireless Keyboard Mouse is compatible with a range of operating systems, including Windows 7/8/10, Mac OS X 10.12, and Android 4.3 or higher. This wide compatibility ensures that it can be used with various devices without issues. Similarly, the Logitech MK850 supports Windows, Mac, ChromeOS, and Android, making it equally versatile. Both products cater to a broad audience, but users should verify compatibility with their specific devices to ensure seamless integration.
Which should you buy?
Choosing between the ProtoArc Ergonomic Wireless Keyboard Mouse and the Logitech MK850 Multi-Device Wireless Keyboard and Mouse Combo ultimately depends on your specific needs. If you prioritise ergonomic design and a higher DPI for precise control, the ProtoArc might be the better choice, albeit at a higher price of £84.99. Conversely, if you seek a well-rounded, budget-friendly option with extensive customisation capabilities, the Logitech MK850 at £72.99 presents a compelling alternative. Consider your primary usage scenarios, budget constraints, and ergonomic preferences to make the best decision for your keyboard and mouse combo needs.
