Dimension comparison
Design and Comfort
The Rii RK209 Silent Wireless Keyboard and Mouse Set offers a full-size keyboard with a slight tilt for ergonomic comfort, while the Logitech MK850 prioritises all-day typing comfort with its cushioned palm rest and deep-profile keys. The ergonomic design of the Rii set reduces wrist strain during extended use, making it suitable for both office and home environments. In contrast, the MK850’s oversized palm rest and adjustable tilt legs cater to individuals who spend long hours typing, ensuring a comfortable experience.
Wireless Connectivity
Both the Rii RK209 and Logitech MK850 feature reliable wireless connectivity, but they utilise different methods. The Rii RK209 employs a 2.4G wireless connection with a range of up to 10 meters, ensuring minimal delays or dropouts. It also uses a single receiver for both devices, simplifying setup. On the other hand, the MK850 allows for seamless switching between three devices, supporting multiple platforms including Windows, Mac, and Android via Bluetooth or USB receiver. This makes the MK850 particularly versatile for users who work across several devices.
Battery Life
In terms of battery longevity, the Rii RK209 boasts impressive lifespan capabilities, delivering up to 15 months of use for the keyboard and 12 months for the mouse with just one AA battery each. This power-saving design with independent switches helps minimise frequent battery replacements. Conversely, the Logitech MK850 uses two AAA batteries, which can last up to three years, thus providing an even longer duration before needing replacements. The extended battery life of the MK850 could be advantageous for users who prefer a hassle-free experience.
Functionality and Productivity Features
The Logitech MK850 is designed with enhanced productivity in mind, offering software options that allow users to customise 12 keys and buttons for shortcuts. This feature can significantly streamline workflows for those who rely on specific software applications. Meanwhile, the Rii RK209 focuses on providing a silent typing experience, making it ideal for environments where noise is a concern. Its high-precision sensor with five sensitivity levels (up to 5000 DPI) ensures precise tracking, which can be beneficial for gamers or graphic designers.
Compatibility
Both the Rii RK209 and Logitech MK850 demonstrate wide compatibility across various operating systems. The Rii RK209 supports Windows XP/Vista/7/8/10, Mac OS, Chrome OS, and Linux, making it a versatile option for diverse users. Similarly, the MK850 is compatible with Windows, Mac, ChromeOS, and Android, allowing users to connect it to multiple devices seamlessly. However, the MK850’s ability to switch between three devices instantly provides an edge for users who frequently alternate between different systems.
Price Comparison
When considering price, the Rii RK209 is significantly more affordable at £14.99 compared to the Logitech MK850, which is priced at £72.99. This substantial price difference may appeal to budget-conscious consumers looking for a basic wireless keyboard and mouse combo. However, the higher price of the MK850 is justified by its additional features and enhanced comfort, making it a worthwhile investment for professionals seeking productivity and ergonomics.
User Experience
The user experience with the Rii RK209 is characterised by its quiet operation, making it particularly suitable for shared workspaces. The full-size keyboard and mouse are designed for comfort, ensuring that users can work without disturbing those around them. Meanwhile, the Logitech MK850 enhances the user experience with customisable functionality through Logitech Options software, allowing for tailored shortcuts that improve efficiency. Additionally, its contoured mouse design fits comfortably in the hand, further enhancing usability during extended periods.
Which should you buy?
Choosing between the Rii RK209 Silent Wireless Keyboard and Mouse Set and the Logitech MK850 Multi-Device Wireless Keyboard and Mouse Combo largely depends on your specific needs and budget. If you are looking for an economical, noise-reducing option suitable for casual use, the Rii RK209 is an excellent choice at £14.99. However, if you require advanced features, superior comfort for long typing sessions, and the ability to switch between multiple devices, the Logitech MK850 at £72.99 is worth the investment. Ultimately, your decision should align with your work habits and the importance of the additional features offered by the MK850.
