Thank you for viewing. This is the CASIO Motion Sensor Runmetrix ASICS CMT-S20R-AS. The data obtained can be used with the app to analyze your running style objectively, which is very helpful. It was likely returned as a new product in April 2023 as a product replacement repair, and I used it about 5 times after that. Then, I injured my foot and haven't used it since. The warranty has expired, but it is in a clean condition. The protective rubber for the main unit cover is slightly dirty. It's visible in the fourth photo. The outer box is also partially torn. I have lost the charging cord and it is not included. I apologize for the inconvenience. The USB cable is an external connection terminal: Micro USB terminal (USB charging). The photos are everything. Please understand that this is a used item. [Product Description] Equipped with GPS function + 9-axis sensor, it can measure the movement of the body during running in detail without a smartphone. By wearing it on your clothes and running, you can measure over 20 running metrics, including pitch, stride, vertical oscillation, and lateral tilt.
