AI Verdict
This is a 2.49-pound full-size low-profile mechanical keyboard with Bluetooth and Logi Bolt connectivity, designed for multi-device productivity across Windows, macOS, Linux, iOS, and Android.
This keyboard is a strong contender for productivity users who need multi-device connectivity and appreciate low-profile mechanical keys. However, the lack of a true wired mode and potential software restrictions on work machines make it a situational fit rather than a universal recommendation.
If you need a more robust typing experience or gaming performance, look for keyboards with dedicated wired connectivity and higher-quality PBT keycaps.

Watch Out For
- The keyboard's 'clicky' switches might not deliver the expected satisfying, audible click, with some users describing the sound as 'falling flat somewhere in the middle'.
- Fast typers might experience a 'double caps' issue, where the shift key's effect extends to the subsequent letter, like 'ANd this'.

What Buyers Say
The quick sleep mode, activating after just 3-4 seconds of inactivity, is a recurring complaint, causing a noticeable 1-2 second delay to wake the keyboard up. Many users praise the seamless multi-device switching and the convenience of the Logi Options+ software, especially the Flow feature for cross-computer control. However, the ABS keycaps are a common point of contention, as they quickly show finger oils and don't feel as premium as some expect. The 'clicky' switches, while mechanical, are sometimes described as not having a truly satisfying click. The lack of a true wired mode is also a frequent disappointment, as the USB-C port is for charging only.
“Man, this keyboard is almost perfect for my work setup, but those ABS keycaps are a fingerprint magnet and the sleep mode is so annoying when I just pause for a second, it's like it forgets I'm here!”
Common Praise
- Switches quickly and reliably between up to three paired devices via Bluetooth or Logi Bolt.
- Logi Options+ software enables useful features like Flow and customizable Fn keys.
- Smart backlighting that activates upon hand proximity and adjusts to light conditions is a battery-saving feature.
- The low-profile mechanical switches provide a comfortable typing experience for extended periods.
- USB-C charging and long battery life (15 days with backlight, 10 months off) are highly valued.
- The aluminum top plate contributes to a solid and premium feel.
Common Complaints
- ABS keycaps get shiny and oily fast, making them feel less premium and look smudged.
- No true wired mode; the USB-C port is only for charging, limiting options for consistent connection.

- The 'clicky' switches are not as audibly satisfying or pronounced as some users expect from a clicky mechanical keyboard.
- Logi Options+ software can be blocked on work computers, preventing access to customization and Flow features.
Ownership Tips
- The battery life is genuinely long, especially with the smart backlighting managing power efficiently.
- Switching between devices is quick enough that it doesn't interrupt workflow, even across different operating systems.
- The low-profile design feels more like a laptop keyboard than a traditional mechanical, which some users prefer for ergonomics.
- The weight of 2.49 pounds makes it stable on a desk but less ideal for frequent travel.
- The 8-degree typing angle, provided by the adjustable feet, is the only ergonomic adjustment available.

Buying Guide
When you're looking at a mechanical keyboard like this, you need to think about how you type and what you're connecting it to. 'Clicky' switches mean you'll hear and feel each keypress, which some love for typing speed and feedback. Wireless connectivity is super convenient for a clean desk, but make sure it supports all your devices and that you don't need a wired backup for critical tasks. Also, consider the keycap material; ABS can get shiny fast, while PBT is more durable.
Mechanical Switches (Clicky)
Unlike membrane keyboards, mechanical switches use individual springs and housings for each key, providing a distinct tactile bump and an audible 'click' sound with each press. This gives you clear feedback that a key has registered, which can improve typing speed and accuracy for some users.
Bluetooth & Logi Bolt Connectivity
This means you can connect wirelessly to multiple devices (like your laptop, tablet, and phone) without needing to plug and unplug cables. Bluetooth is standard, while Logi Bolt uses a dedicated USB receiver for a potentially more stable and secure connection, especially in busy wireless environments.
Low-Profile Keys
These keys are shorter than traditional mechanical keys, resulting in a flatter keyboard profile. This can feel more natural and comfortable for some, reducing wrist strain over long typing sessions, similar to a laptop keyboard but with the benefits of mechanical switches.
Smart Illumination
The backlighting automatically turns on when your hands get close and adjusts its brightness based on the room's lighting. This saves battery life by only lighting up when needed and ensures you can always see the keys clearly, whether in a bright office or a dim room.
Alternatives
If this keyboard doesn't quite fit, look for models with PBT keycaps for better durability, dedicated wired connectivity for gaming or critical work, or a more compact form factor if portability is a priority.
