Peace be upon you, an optical device for sale, original from Al-Faleh in Khamis Mushait, with its packaging. Little used, by God. The original purchase price was 1600 riyals. The reason for selling is lack of use and it sitting in its place for a long time, and perhaps someone needs it. The price is negotiable and for face-to-face meeting. You can inspect the device if we meet. Its specifications include a full screen and handles that show your heart rate, your speed, how much you've covered, how much you've burned, and many other things on the screen.
