By Igor Ermakov November 13, 2023 3 Min Read


In a market brimming with ergonomic solutions, the Nulea RT05A Wireless Ergonomic Keyboard stands out as a notable contender. This review delves deep into its features, functionality, and user experiences, with a particular focus on its standing as a "wireless split keyboard."

Design and Build Quality

The Nulea RT05A is ingeniously crafted with an ergonomic split design, aimed at reducing wrist strain and promoting a more natural typing posture. Users have praised the build quality, noting the solid feel and weight of the keyboard. The concave keys are a highlight, fitting the fingers comfortably. However, some professional users like programmers find the placement of certain keys like home, end, page up, and page down, which are not segregated into a dedicated block, to be a drawback. This design choice has been a dealbreaker for some, especially those accustomed to traditional key layouts.

Connectivity and Battery

The rechargeable battery is a significant advantage, reducing the need for constant battery replacements. However, some users have noted issues with the charging process and the duration of battery life, suggesting room for improvement in future iterations.

Key Layout and Functionality

The keyboardโ€™s layout receives mixed reviews. The ergonomic split and key spread are generally well-received, but the dual-purpose function keys, requiring the use of an Fn button to access F1, F5, etc., have been criticized. This feature, in particular, seems to alienate traditional Windows users who prefer direct access to function keys. The unusual positioning of the delete key also mirrors a Mac-style layout, which might not sit well with all users.

Lighting and Aesthetics

The backlit keys with adjustable colors and brightness add an aesthetic appeal to the Nulea RT05A. Users appreciate the option to customize the lighting, although some have mentioned the lights could be brighter for better visibility. The durability of the key lettering is a plus, with no concerns about them fading over time.

Ergonomics and Comfort
