Price Comparison

When considering budget, the ProtoArc Foldable Keyboard and Mouse is priced at £60.95, whereas the Logitech MK850 comes in at a higher £72.99. This represents a £12.04 difference, with the ProtoArc option being more economical for those looking to save. Both products offer excellent features, but if cost is the primary concern, the ProtoArc holds an advantage, making it a suitable choice for cost-conscious consumers without sacrificing essential functionalities.

Design and Portability

The ProtoArc Foldable Keyboard and Mouse is designed for on-the-go productivity. Its ultra-slim profile and foldable mechanism make it highly portable, ideal for frequent travellers. The inclusion of a carrying hard case ensures that it can be easily transported alongside your devices. On the other hand, the Logitech MK850 focuses on comfort and ergonomics with a cushioned palm rest and adjustable tilt legs, prioritising comfort for extended use. While the MK850 provides a solid and comfortable typing experience, it lacks the same level of portability as the ProtoArc, making the latter a better choice for those who travel frequently.

Functionality and Performance

The ProtoArc Foldable Keyboard and Mouse offers a full-size 105-key layout with dedicated function and number pads, which enhances productivity for tasks like spreadsheets and coding. Its ability to connect seamlessly to three devices via Bluetooth and a 2.4G connection allows for flexibility across different platforms. In contrast, the Logitech MK850 also supports multi-device connectivity, allowing users to switch between three devices effortlessly. However, the MK850 boasts additional features, such as the Logitech Options software that enables users to customise 12 keys and buttons for shortcuts, enhancing overall productivity. Thus, while both products perform well, the MK850 has a slight edge in customisation capabilities.

User Experience

With the ProtoArc, users benefit from whisper-quiet scissor switches and low-profile keys, providing a noise-reducing experience that makes it suitable for quiet environments like libraries or cafes. The included precision mouse operates at three adjustable DPI settings, ensuring adaptability for various tasks. In comparison, the Logitech MK850 is designed for comfort over extended periods, with its deep-profile keys and contoured mouse designed to fit comfortably in the palm. The MK850 also features hyper-fast scrolling, allowing users to navigate through documents and web pages smoothly. This distinction highlights that while ProtoArc prioritises quiet operation, the MK850 emphasises comfort and ease of use.

Battery Life and Power Management

The ProtoArc Foldable Keyboard and Mouse excels in battery management, with the keyboard boasting a standby time of up to 150 days and the mouse up to 200 days, both rechargeable via a Type-C cable. This long battery life reduces the frequency of recharging, making it convenient for users. In contrast, the Logitech MK850 utilises two AAA batteries that can last up to three years, providing an impressive lifespan without the need for frequent replacements. While both options offer effective power solutions, the MK850's long battery life without the need for recharging may appeal more to users who prefer a low-maintenance device.

Compatibility

The ProtoArc Foldable Keyboard and Mouse supports multiple operating systems, including Windows, macOS, Chrome OS, iPadOS, and Android, making it versatile for a range of devices. It can connect with up to three devices, facilitating easy transitions between them. The Logitech MK850 also prides itself on its compatibility, working with Windows, Mac, ChromeOS, and Android, and similarly allows users to pair with up to three devices. However, the MK850's dedicated Logitech Options software allows for additional functionality and customisation, enhancing its usability across devices. Thus, while both products are compatible with a wide range of systems, the MK850 may offer a more tailored experience.

Target Audience

The ProtoArc Foldable Keyboard and Mouse is particularly well-suited for frequent travellers and professionals who need a portable solution without compromising on functionality. Its focus on portability, quiet operation, and multi-device connectivity makes it an attractive option for those who work in varied environments. The Logitech MK850, in contrast, targets users who prioritise comfort and customisation in their typing experience, making it ideal for office workers or anyone who spends long hours at a desk. Each product caters to distinct user needs, with ProtoArc appealing to mobility-focused individuals and MK850 to those valuing comfort and productivity.

Which should you buy?

Deciding between the ProtoArc Foldable Keyboard and Mouse and the Logitech MK850 depends on your specific needs. If you seek a more affordable, portable option that provides essential functionality for on-the-go productivity, the ProtoArc is an excellent choice at £60.95. However, if your priority is comfort for extended use, coupled with customisation features that enhance productivity, the Logitech MK850 at £72.99 may be worth the investment. Ultimately, each product offers unique advantages, so your choice should align with your lifestyle and usage preferences.
