Price Comparison
The ProtoArc Bluetooth Wireless Keyboard and Mouse is priced at £29.99, significantly lower than the Logitech MK850 Multi-Device Wireless Keyboard and Mouse Combo, which retails for £72.99. This £43 price difference highlights a substantial budget-friendly option in the ProtoArc, making it an attractive choice for users who want to save money while still obtaining a functional keyboard and mouse set. The price of the Logitech may be justified by its additional features and enhanced design, appealing to those willing to invest more for added comfort and functionality.
Design and Ergonomics
In terms of design, both the ProtoArc and the Logitech MK850 offer ergonomic features, but they cater to different preferences. The ProtoArc features a non-detachable wrist support, which is designed for stability and comfort during long typing sessions. It also has adjustable tilt legs that provide a comfortable typing angle of 7°. On the other hand, the Logitech MK850 includes an oversized cushioned palm rest and a curved key frame, designed for all-day typing comfort. Users may prefer the ProtoArc's adjustable typing angle or the Logitech's cushioned support depending on their personal comfort needs.
Device Compatibility
Device compatibility is another crucial factor where the two products differ. The ProtoArc supports connections via 2.4GHz and dual Bluetooth, allowing users to easily switch between three devices, including laptops, tablets, and PCs. It is compatible with various operating systems, including Windows, Mac, and Android. Conversely, the Logitech MK850 also allows seamless switching between three devices but specifically highlights its compatibility with Windows, Mac, ChromeOS, and Android. This flexibility in device pairing makes both products versatile, but the ProtoArc's dual connection method may provide an edge for users who frequently switch between device types.
Battery Life
Battery life is a critical consideration, especially for wireless devices. The ProtoArc boasts a rechargeable set with built-in lithium batteries, claiming a lifespan of up to 45 days under typical use. This feature is complemented by a Type-C charging capability, enhancing convenience. In contrast, the Logitech MK850 operates on two AAA batteries, offering an impressive three-year lifespan. While the ProtoArc's rechargeable feature may appeal to users looking for sustainability, the extended battery life of the Logitech could be a deciding factor for those who prefer minimal maintenance.
Typing Experience
When it comes to typing experience, the ProtoArc features scissor-switch keys that provide a smooth, quiet typing sensation aimed at reducing finger fatigue. It also includes 13 multimedia keys for quick access to essential functions, making it efficient for tasks such as document creation and data entry. On the other hand, the Logitech MK850's deep-profile keys are designed for comfort and quiet operation, enhancing productivity with its versatile key functions. The choice between these two typing experiences may depend on personal preferences regarding key feel and the importance of additional multimedia functionality.
Mouse Features
The mouse included in the ProtoArc set is designed specifically for right-handed users, featuring silent clicking and adjustable DPI settings (1000/1600/2400). This adaptability is ideal for precise control in office settings. In contrast, the Logitech MK850's contoured mouse has a soft rubber surface for comfort and includes a hyper-fast scrolling wheel, making it suitable for navigating through documents and webpages quickly. Users who prioritise mouse ergonomics may find the Logitech's design more appealing, while those focused on precision might favour the ProtoArc's adjustable DPI.
Additional Software and Functionality
The Logitech MK850 distinguishes itself with additional software support through Logitech Options, allowing users to assign 12 custom shortcuts to keys and buttons, enhancing productivity. This feature can be a game-changer for professionals who rely on quick access to frequently used functions. The ProtoArc lacks such software integration, which may limit its customisation options. Users who value enhanced functionality and personalisation may lean towards the Logitech MK850 for its superior software capabilities.
Which should you buy?
Choosing between the ProtoArc Bluetooth Wireless Keyboard and Mouse and the Logitech MK850 Multi-Device Wireless Keyboard and Mouse Combo ultimately depends on individual needs and preferences. The ProtoArc is a budget-friendly option with ergonomic features and a rechargeable design, making it ideal for those seeking functionality without a significant financial investment. Conversely, the Logitech MK850 offers advanced features such as extended battery life, customisable software, and superior comfort, justifying its higher price for users who prioritise these aspects. Consider your specific requirements in terms of comfort, device compatibility, and productivity features to make the best choice for your workspace.
