Dimension comparison
Price Comparison
When considering price, the Rii Dual Mode Wireless Keyboard with Touchpad Mouse is significantly more affordable at £21.98, compared to the Perixx Periduo-605, which is priced at £49.99. This means that the Perixx is over twice the cost of the Rii, making it a substantial investment for users on a budget. The Rii keyboard not only offers a lower price point, but it also provides a variety of features that are appealing to users who require a portable solution. In contrast, the Perixx, while more expensive, may appeal to those looking for an ergonomic design, though the cost difference is notable.
Ergonomics and Comfort
The Perixx Periduo-605 stands out in terms of ergonomic design, featuring a split-key layout and a built-in wrist rest that promotes a natural wrist position. This is essential for users who spend long hours typing, as it helps reduce wrist strain and enhances overall comfort. The adjustable DPI settings of 1000, 1500, and 2000 offer precision control, catering to various user preferences. Conversely, the Rii Dual Mode Wireless Keyboard, while portable and equipped with a touchpad, does not prioritise ergonomic features to the same extent. Its compact design may sacrifice comfort for convenience, making the Perixx the better choice for ergonomics.
Connectivity Options
Connectivity is another area where these two products differ significantly. The Rii Dual Mode Wireless Keyboard offers dual-mode connectivity, allowing users to switch seamlessly between Bluetooth and 2.4G modes. This versatility is ideal for those who use multiple devices and need a reliable connection. Meanwhile, the Perixx Periduo-605 utilises a 2-in-1 USB Nano Receiver for connectivity, which is straightforward but lacks the flexibility of Bluetooth. With a 30-foot operating range, the Perixx provides ample freedom of movement, but it may not match the convenience offered by the Rii's dual connectivity.
Battery Life and Power
Battery life is a critical factor for wireless keyboards, and the Rii has a rechargeable lithium battery that can last up to 10 hours with the backlight on and 46 hours without it. This is a significant advantage for users who prefer a backlit keyboard for low-light conditions. In contrast, the Perixx Periduo-605 requires four AAA batteries (not included), which can be inconvenient as users will need to replace them periodically. While the Perixx offers a reliable performance, the Rii’s rechargeable feature makes it a more convenient option for users who wish to avoid the hassle of battery replacements.
Design and Portability
In terms of design, the Rii Dual Mode Wireless Keyboard is compact and lightweight, making it easy to carry around. Its integrated touchpad reduces the need for a separate mouse, enhancing portability for users who are often on the go. The Perixx Periduo-605, with its full-size keyboard and vertical mouse, is designed more for a stationary setup and may not be as travel-friendly. The ergonomic features of the Perixx may appeal to home-office users, but for those needing a keyboard that is easy to transport, the Rii's design is more suited to that purpose.
User Experience and Features
The user experience offered by the Perixx Periduo-605 focuses on comfort and ease of use, thanks to its advanced split-key design and wrist support. The low-profile keys reduce travel distance, making typing less strenuous. On the other hand, the Rii Dual Mode Wireless Keyboard focuses on functionality, providing backlit keys for low-light use and a unique scroll wheel for easier navigation. Both keyboards cater to different user needs; the Perixx is ideal for long typing sessions, while the Rii is better suited for casual use and multitasking across devices.
Compatibility
Both keyboards boast compatibility with a range of operating systems, including various versions of Windows and Linux. The Perixx Periduo-605 is compatible with Windows 7, 8, and 10, ensuring that it can be used with most modern devices. The Rii Dual Mode Wireless Keyboard expands its compatibility further by supporting Bluetooth connections, making it accessible to tablets and smartphones as well. This wider range of compatibility could be a deciding factor for users who utilise multiple devices.
Which should you buy?
In conclusion, the decision between the Perixx Periduo-605 and the Rii Dual Mode Wireless Keyboard ultimately depends on your specific needs. If ergonomic design and comfort during prolonged use are your top priorities and you don’t mind spending £49.99, the Perixx is a strong choice. However, if you are looking for a budget-friendly option with versatile connectivity and portability for just £21.98, the Rii keyboard is an excellent alternative. Your choice should align with whether you favour ergonomics and comfort or portability and affordability.
