    X3 slim

    Fast shipment and packaged well. Item paired with my 2020 Mac mini with no issues. Construction of X3 was excellent. The tactile feel was spot on. The charging port was well placed. Ergonomics was excellent.

    Keyboard

    I love this Keyboard. The only issue I have is that it keeps losing the bluetooth connection.

    I'm using a MacBook Pro 2025
