Switch click durability: You mention “button durability: 10 million clicks”. Many brands claim 50 million or more. Make sure the spec says at least 10 million (or more) for the version you're buying.

Cable length, thickness, durability: “150 cm high‑speed USB PVC cable” with “3 mm diameter high strength data line” and “10 kg maximum pulling force” are quite specific. Usually sellers do not include pulling force or exact diameter. If possible, ask the seller/manufacturer for those data.

Key profile / long profile: If by “long‑profile keys” you mean tall keycaps or certain key cap profile, check pictures or ask. Also “double‑shot inject keycaps” or “double‑shot keycaps” are often listed, but ensure that the legends/key labels are truly double shot (so they don’t fade).

Win key disable: Many models have “Win key lock / disable” in gaming mode; verify that it's physical or software mode and that it works reliably.

Interchangeable WASD & arrow keys: Usually means the keycaps for WASD or arrows are colored differently or shaped similarly so you can swap; check if the keyboard includes extra keycaps or if they’re pre-installed
