I bought this used from a friend. After I got it, I realized it wasn’t compatible with my Garmin fénix 6 watch, so I really only used the computer to monitor my speed 🤷‍♀️ I used it for two summers. Still in good working condition. Garmin Edge 530 GPS will come with box, manual, computer, and plastic mount (as seen in photo on my tri bars).
