Switching from the K500 to the MX Keys S feels like going from a basic commuter car to a luxury ride. The difference is immediate. The keys have a smooth, precise feel with just the right amount of travel, and the typing experience is noticeably quieter and more refined. The backlighting is smart and responsive, something the K500 never offered, and it makes late‑night work so much easier.
The build quality is excellent — solid, premium, and surprisingly comfortable even during long typing sessions. Paired with the MX Palm Rest, it's easily the most comfortable setup I've ever used. Connectivity is flawless, and switching between devices is instant.
If you're upgrading from an entry‑level keyboard like the K500, the MX Keys S will feel like a massive leap forward in quality, comfort, and performance. Absolutely recommend it.
