Design and Features
The design of the Logitech Signature Slim Solar+ K980 reflects the aesthetic established by the MX Keys series, featuring a minimalist gray finish, a slim profile, and gently rounded corners. While the solar panel along the top edge slightly alters its sleek appearance, the keyboard remains an elegant addition to both sophisticated office environments and gaming setups, albeit perhaps lacking the flair of RGB-lit counterparts.
However, one notable absence is the backlighting, which differentiates this model from the MX Keys series. In well-lit conditions, usability remains unaffected, but in dimly lit spaces, the lack of illumination may hinder visibility—a potential drawback for gamers who prefer a darker ambiance.
The legends on the keys are screen-printed, a common method for this type of keyboard, but this may lead to wear over time. In contrast, many modern gaming keyboards utilize more durable methods for key legends, such as double-shot or dye-sublimated techniques.
With a thickness of under 10mm, except for a slightly thicker 16mm section at the back for an improved typing angle, the keyboard’s low-profile design is complemented by six rubber feet that prevent slipping. Notably, the absence of a USB port for charging eliminates the need for a battery compartment, contributing to a seamless chassis design. Logitech claims the rechargeable battery can last up to 10 years, minimizing concerns about maintenance.
The keyboard features a full-size layout, specifically in a UK ISO configuration, along with four dedicated keys for quick access to functions such as calendar, microphone mute, camera off, and PC lock. Additionally, it can connect to three Bluetooth devices simultaneously, allowing for effortless switching between devices, which is particularly useful for users who alternate between a Mac and a PC.
Performance
The overall build quality of the K980 is commendable. While it exhibits some flex when lifted from the ends, the design ensures stability during typing. The keys provide a crisp and responsive feel, striking a balance between resistance and ease of use.
Utilizing a laptop-like scissor switch, this keyboard may not match the durability of mechanical counterparts, but it generally outlasts traditional rubber dome switches found in budget keyboards. However, heavy typists may find that the keys begin to lose responsiveness sooner than the advertised battery life suggests. Logitech has yet to disclose the lifespan of the switches, but for moderate users, this should not pose a significant issue.
Battery Life
Logitech confidently asserts that the K980 can last up to four months in total darkness. When exposed to light, the solar panel continuously charges the battery, potentially extending its lifespan to an impressive 10 years or more.
For those curious about the light requirements, Logitech indicates that charging begins at 200 lux. Practically, a small desk lamp or a ceiling light can easily provide sufficient illumination for charging, while even minimal sunlight can keep the keyboard powered.
Price
The Logitech Signature Slim Solar+ K980 is priced at .99 / £99.99, positioning it as a premium yet reasonably priced option. Given its unique solar-charging capabilities and extended battery life, the price reflects its value. However, the absence of backlighting and the use of screen-printed legends may slightly detract from its overall appeal.
