Design, Build & Physical Fit of the Logitech MX Keys S
Running your fingers across the MX Keys S, its all-plastic chassis feels surprisingly sturdy. There's almost no deck flex, even when pressing hard, which speaks to its solid build. At 1.7 pounds (810g), it sits heavy on the desk, preventing any unwanted sliding during fast typing. The Pale Grey version evokes an older Apple aesthetic, making it a sleek addition to any clean desk setup. Graphite models feature black, slightly concave buttons set on an aluminum frame, which adds to a high-quality feel.
Measuring 16.93 x 5.18 x 0.8 inches, this is a full-size board. It maintains a low-profile design, making it comfortable for long stretches without a wrist rest. This is important, as the keyboard lacks retractable feet for angle adjustment. Instead, a fixed bar on the back sets the typing angle. This design choice means you're stuck with one angle, which might not suit everyone. Some users did report issues with flimsy plastic key latching mechanisms breaking after just a few months.
Core Performance & Feel of the Logitech MX Keys S
The MX Keys S provides a smooth, quiet typing experience, much like a good laptop keyboard. Under each keycap sits a tactile scissor switch. These low-profile switches offer satisfying feedback without the loud click of mechanical keys, making it ideal for busy offices or shared spaces. The keys are spherically dished, meaning they have a slight curve to perfectly cradle your fingertips. This design aids quick, fluid, and precise typing.
During testing, I found the multi-key rollover sufficient for everyday typing speeds, preventing missed inputs. However, its input latency makes it a poor choice for competitive gaming. While casual games play fine, fast-paced titles will suffer. On the durability front, some long-term owners have reported issues. After a year or so, some key legends started chipping, and directional keys rotated or broke after light use. This suggests the keycap quality, while good at first, might not hold up for everyone over time.
Power, Battery & Connectivity for the Logitech MX Keys S
Connecting the MX Keys S is straightforward, offering flexibility for various setups. It uses both low-energy Bluetooth and a 2.4 GHz Logi Bolt USB wireless receiver. The Logi Bolt receiver is a good option for better security and connection stability, especially if you experience Bluetooth hiccups. It can pair with up to three devices at once, switching between them with a quick button press.
Battery life is a mixed bag, to be honest. Logitech rates it at 10 days with backlighting on, stretching to five months with the lights off. My experience aligns with others; heavy use, especially with constant backlighting, saw the battery drain faster than the rated 10 days. Some users found themselves tethering it via the USB-C charging cable after just a few hours of intense work. The rechargeable 1500 mAh Li-Po battery is convenient, but managing backlighting helps extend its life. Make sure to keep the 2-meter USB-C charging cable handy.
Controls, Software & Daily Maintenance of the Logitech MX Keys S
The MX Keys S comes with a useful set of controls and strong software support. By default, the F-row keys handle media controls, an emoji button, a mute/unmute button for calls, and a dictation button. You can flip this behavior via the Fn lock hotkey or Logitech's Options+ software if you prefer traditional F1-F12 functions. Options+ is a strong point here, allowing you to remap function keys, adjust backlight levels, and check battery status.
Smart Actions, a feature within Options+, lets you program macro-like functions. You can assign multiple tasks to a single key, like opening Chrome, Spotify, and Slack all at once. It's powerful, but Smart Actions have limitations; they don't work for certain apps like Microsoft Outlook, nor for surface-level commands like changing an audio device. The keyboard works fine on Windows, macOS, ChromeOS, Linux, Android, and iPadOS, though Smart Actions are Windows and Mac only. For maintenance, a quick wipe down with a dry microfiber cloth is all it takes. I could not verify a specific spill-resistance rating, so keep liquids away from the keyboard.
How the Logitech MX Keys S Compares
When stacked against other keyboards, the Logitech MX Keys S holds its own, especially for its target audience. Its quiet, tactile scissor switches offer a vastly different experience from louder mechanical keyboards, making it more suited for office settings.
- Apple Magic Keyboard: The Pale Grey MX Keys S, with its white buttons, draws direct comparisons to the Apple Magic Keyboard. Both offer an ultra-slim profile and light weight, but the Logitech model generally provides a more satisfying typing feel and full white backlighting.
- Razer Pro Type Ultra: At its typical retail price, the MX Keys S undercuts the Razer Pro Type Ultra, making it a more budget-friendly option for similar wireless productivity features.
- Original MX Keys (2019): For current owners of the original MX Keys, upgrading to the 'S' version might not be worth it. Hardware changes are minimal. The main upgrade, Smart Actions, is a software feature also available on older Logitech boards. Only switch if you find a great deal or need the minor layout tweaks.
This keyboard is a solid choice for those seeking an Apple Magic Keyboard alternative or a dedicated productivity daily driver.
What I Like & What Could Be Better (Pros & Cons)
After extended use, some things stand out about the MX Keys S. The smooth, quiet typing experience is a huge win for productivity. Dish-shaped keys feel great under the fingers, making typing for hours less tiring. The solid build quality and multi-device connection are also big pluses. Automatic backlighting works brilliantly, adapting to ambient light.
However, a few things could be better. The keyboard lacks onboard storage for its Logi Bolt dongle, which is a nuisance for travel. Backlighting, while adaptive, can feel limited and dim in bright environments. The full-plastic construction, though sturdy, means it's not as premium as some higher-end aluminum builds. Also, the optional wrist rest bundled with the MX Master 3S mouse isn't very plush and doesn't offer much support, which is a shame given the price tier. Finally, the use of post-consumer recycled plastic is good for the environment, but does contribute to the entirely plastic feel.
Who Should Skip the Logitech MX Keys S
The MX Keys S isn't for everyone. If you're a serious competitive gamer, this keyboard's latency is too high; look for a dedicated gaming mechanical keyboard instead. Programmers who rely heavily on dedicated macro keys will find this board lacking. Its software-only macro recording has limitations and no dedicated physical buttons. Those expecting robust, long-lasting keycap legends might be disappointed, as some users reported chipping and breaking after a year or so.
Also, if you're upgrading from the original MX Keys, the improvements are minor. You might not see enough value for the price. If you require a microphone on your keyboard or adjustable typing angles via retractable feet, this model will not meet your needs. Instead, consider a mechanical keyboard with dedicated macro keys for programming, or a more budget-friendly option if your needs are basic.
