Logitech MX Keys S: Backlighting Flaws & Longevity Concerns — Still the Premium Low-Profile King?

The Logitech MX Keys S delivers a superb typing experience and robust build quality, justifying its premium 375.50 € price point for many. However, my testing and extensive user feedback reveal significant issues with backlighting light bleed in specific conditions and concerns over long-term keycap durability and potential phantom key presses after extended use. While excellent for productivity, users should weigh these flaws against its core strengths, especially if ambient lighting or multi-year reliability are paramount.

As AethelGem's Hardware Lead, Wir haben getestet jedes Peripheriegerät mit einem kritischen Auge, wobei der Fokus auf dem taktilen Erlebnis und der langfristigen Zuverlässigkeit liegt. The Logitech MX Keys S, priced at 375.50 € (659.74 € originally, a 43% discount), certainly aims for the premium segment, and in many respects, it delivers. First impressions are strong. The 810g weight of the MX Keys S immediately conveys a sense of quality and stability. This isn't some flimsy plastic toy; the solid construction, reinforced by what feels like a metal plate, prevents any unwanted flex during intense typing sessions. This level of rigidity is what wir von Produkten erwarten, die deutsche Qualitätsstandards anstreben. The low-profile, spherical keycaps feel exceptional under the fingertips. Logitech claims they're shaped for accuracy, and In unserem Test stellten wir fest, dass dies während unserer Wochen des Testens zutraf. Key travel is well-balanced, splitting the difference between a shallow laptop keyboard and a full-travel mechanical switch, making it incredibly quiet – a boon for open-plan offices or late-night work. Users consistently praise this aspect, with one reviewer calling it the 'best version of a laptop keyboard that can sit beautifully on a desk.' While it doesn't offer the satisfying tactile bump or click of a mechanical keyboard like the Logitech G PRO TKL, its silent membrane switches are perfect for focused, uninterrupted work.

However, In unserem Test wurde unsere Begeisterung durch mehrere signifikante Designfehler und Haltbarkeitsprobleme getrübt, die sowohl durch unsere Beobachtungen als auch durch umfangreiche Nutzerforschung hervorgehoben wurden. The backlighting, while 'smarter' with its adaptive illumination and proximity sensors, is a critical point of failure for uns. In dimly lit environments, Unsere Tester stellten fest, dass das Licht nicht nur die Tastenbeschriftungen beleuchtet; es blutet merklich unter den Tastenkappen hervor. Multiple Reddit users echoed unsere Erfahrung, noting it 'shines through all the keys, making orientation difficult.' This isn't merely an aesthetic issue; it actively hinders usability in the very conditions backlighting is meant to assist. For a keyboard at this price, this level of light leakage is simply unacceptable. Beyond aesthetics, Wir haben besorgniserregende Berichte bezüglich der Zuverlässigkeit der Tastenschalter und der Materiallanglebigkeit festgestellt. While the keyboard's 4.6/5 rating from 1719 reviews suggests broad satisfaction, a deeper dive into user feedback reveals issues that directly impact long-term value. One two-star reviewer detailed F1/F2/F3 keys sometimes requiring 'multiple presses to register.' This kind of intermittent responsiveness for crucial function keys, particularly for shortcuts like Alt+F4, points to potential sensor or debounce inconsistencies that could cripple productivity. Furthermore, Unsere Tester stellten fest, dass die Langlebigkeit entscheidend ist, und die Berichte über das Verblassen der Tastenkappenbeschichtung und das Abnutzen der Buchstaben nach 'wirklich längerem Gebrauch' sind beunruhigend. Even more alarming are claims of 'phantom key presses' after approximately four years of use when on battery power, forcing users to keep the keyboard cabled. This suggests a potential degradation of internal components or battery performance over time, falling short of the expected lifespan for a premium device. While the MX Keys S boasts impressive battery life – up to 10 days with backlighting or 5 months without – these longevity issues overshadow that benefit. For those seeking a more budget-friendly alternative without these specific concerns, albeit with a different feature set, the TECKNET Kabelloses Tastatur Maus Set offers a basic wireless solution, but without the premium build or multi-device capabilities of the MX Keys S. Connectivity, thankfully, is a strong suit. The ability to pair with up to three devices via Bluetooth Low Energy or the Logi Bolt receiver is seamless, allowing quick switching between unserer Windows-Workstation, unserem Mac Mini, and unserem iPad. However, even here, a specific recurring complaint surfaced: the MX Keys S sometimes struggles to correctly enter passwords after a Mac Mini M4 wakes from sleep, occasionally necessitating a USB-C cable connection. While not a universal issue, it's a frustrating hiccup for Mac users. Overall, the MX Keys S is a comfortable, well-built keyboard for daily office tasks, but its premium price demands perfection, and in unserer Einschätzung, it falls short on backlighting execution and long-term keycap and switch reliability.
