Dimension comparison
Design and Ergonomics
The design and ergonomics of the Perixx Periduo-605 and Rii Keyboard and Mouse Set differ significantly, targeting different user needs. The Periduo-605 features an advanced split-key design that reduces wrist strain by positioning keys optimally for each hand, promoting a natural wrist position with its built-in plastic wrist rest. This ergonomic aspect is essential for users who spend long hours typing, as it enhances comfort and reduces the risk of repetitive strain injuries. In contrast, the Rii Keyboard and Mouse Set offers a standard wired design that is lightweight and portable, appealing to users who prefer a space-saving solution. The ergonomic features, while present, are basic compared to the Periduo-605, making it less suited for extensive use.
Performance and Functionality
When it comes to performance, the Perixx Periduo-605 excels with its adjustable DPI settings of 1000, 1500, and 2000, allowing for precise control during use. This feature is particularly beneficial for users who require accuracy, such as gamers or graphic designers. The Rii Keyboard and Mouse Set operates with a standard optical 1000 cursor speed precision sensor, which is adequate for general tasks but lacks the advanced options of the Periduo-605. The Periduo-605 also utilises a 2-in-1 USB Nano Receiver for connectivity, offering an impressive 30-foot operating range, whereas the Rii set is a wired combination, limiting mobility.
Compatibility
Compatibility is another area where the two products differ. The Perixx Periduo-605 is compatible with Windows 7, 8, and 10, and offers a hassle-free Plug and Play installation, which simplifies setup for most users. Additionally, the package includes a 12-month UK warranty for added peace of mind. On the other hand, the Rii Keyboard and Mouse Set boasts a broader compatibility range, working with Windows, Mac OS, Chrome OS, and Linux OS. This makes it a versatile choice for users with different operating systems, but it does not provide the same level of ergonomic support or advanced features found in the Periduo-605.
Build Quality and Durability
Build quality and durability are crucial factors to consider when choosing between these two products. The Perixx Periduo-605 is designed for long-term use, with a focus on comfort and support. Its features, such as the low-profile keys and durable wrist rest, cater to users who prioritise ergonomics. The Rii Keyboard and Mouse Set, while described as robust, primarily focuses on a classic design that is wear-resistant and splash-proof. It claims to withstand up to 5 million keystrokes, which is commendable for a budget option. However, the overall build quality of the Periduo-605 is likely to be superior, given its ergonomic design and intended use for extensive typing.
Price and Value
Price is a significant factor when comparing the Perixx Periduo-605 and Rii Keyboard and Mouse Set. The Periduo-605 is priced at £49.99, reflecting its advanced ergonomic features and build quality. This higher price point may be justified for users who require a comfortable and supportive typing experience. Conversely, the Rii Keyboard and Mouse Set is available at just £14.98, making it an attractive option for budget-conscious consumers. While it offers basic functionality and portability, the value it provides is fundamentally different compared to the more specialised Periduo-605.
User Experience
User experience plays a vital role in determining which product is better suited to individual needs. The Perixx Periduo-605 is designed for those who prioritise ergonomic considerations, making it an excellent choice for users who spend extended periods at their desks. The comfort of the built-in wrist rest and the split-key layout can significantly enhance typing ease and reduce fatigue. In contrast, the Rii Keyboard and Mouse Set, while functional, may not provide the same level of comfort over prolonged use, particularly due to its standard design and lack of advanced ergonomic features. Users seeking a simple, no-fuss setup may appreciate the Rii set, but those with specific ergonomic needs will likely favour the Periduo-605.
Which should you buy?
Choosing between the Perixx Periduo-605 and the Rii Keyboard and Mouse Set ultimately depends on your specific needs and budget. If you prioritise ergonomic design, advanced features, and long-term comfort, the Periduo-605 is a superior choice at £49.99. However, if you are looking for a basic, budget-friendly option for casual use, the Rii set at £14.98 offers a good balance of functionality and portability. Consider how you plan to use the keyboard and mouse, as this will guide you towards the option that best fits your requirements.
