Logitech has recently introduced the Signature Slim keyboard, emphasizing functionality, sustainability, and a smooth user experience. We at senses have had the opportunity to evaluate it in a combined package with the Signature Plus M750 mouse.
We have previously reviewed several Logitech products at senses. This evaluation will focus on the new features and how these accessories compare to existing models from the same manufacturer.

Slim Signature Keyboard K950 – A Familiar Design
The keyboard, designated the Slim Signature Keyboard K950, is also available separately in black and white. It shares many similarities with the well-regarded MX Keys S, with a few key distinctions. Visually, the designs are nearly identical. The Slim Signature is slightly thinner than the MX Keys S, a difference noticeable only when placed side-by-side. The primary focus of the Signature series is sustainability, with components reportedly manufactured using a significant amount of recycled plastic. Logitech also offers a comprehensive exchange program for damaged keycaps, alongside solutions for responsibly recycling accessories at the end of their lifespan. The Slim offers a similar feel and minimal sound output to the MX Keys S. A key difference lies in the Slim’s lack of backlighting and its reliance on two AAA batteries (included) for power. This design choice feels like a step back, particularly considering the emphasis on sustainability. A rechargeable, integrated battery would have been a more efficient solution, even with the option to use rechargeable batteries. Compared to the MX Mechanical Mini, which offers other distinct advantages, we appreciate the enhanced precision offered by the Slim Signature.
Logitech’s Logi Options+ provides a streamlined user interface, offering a comprehensive overview and settings for all compatible Logitech devices. Firmware updates are executed with a single click, and users can customize the function keys via Smart Actions. One notable feature is the “Social Media Break,” a macro designed to open four social media windows incrementally, facilitating periodic breaks during the workday. However, a minor translation error exists in the Swedish version, which could be clarified. The software is intuitive and well-designed, serving as a prime example of effective software presentation.

The Signature Plus M750 mouse offers a comparable user experience to the MX Master 3S, albeit without some of the higher-end features. The mouse operates quietly; the clicks are tactile but produce minimal audible sound. The scroll wheel offers variable speed settings for different functionalities. Programmable side buttons allow users to assign functions such as forward and back navigation (or customize them per application). The main drawback of the mouse, besides its reliance on a single AAA battery (which offers a projected lifespan of one to two years), is its relatively compact size. This may be a consideration for users with larger hands.

Both the mouse and keyboard feature buttons for seamless switching between three paired devices. The package also includes a USB dongle for Logi Bolt connectivity.
The keyboard is available separately for approximately 1000 SEK (the mouse is not currently sold separately), while the combo package is priced around 1300 SEK. The kit’s size makes it suitable for mobile use, although full-size keyboards are not always ideal for travel. It also functions effectively as a stationary solution in a home or office environment. The package offers considerable value for its price point; however, users with larger budgets may consider the MX Keys S and a mouse from the Master Series for an enhanced experience.
