## Before you buy

- The connection details are inconsistent: the specifications field lists Bluetooth, USB-C and Wi-Fi, while the feature description identifies 2.4GHz wireless, Bluetooth and wired USB-C, confirm the connection options for the selected listing.

The listing describes the Mercury K1 Pro as hot-swappable and identifies its switches as GravaStar x Kailh Speedy Mint linear switches.
