I received this from a friend, but I've kept it in storage without ever using it, so I personally think it's in good condition. It only includes the main unit and charger. You can charge it by purchasing a micro USB cable separately at a 100-yen shop or similar. How about it for your collection? I charged it to about 98% and used it for 30 minutes to an hour, and it worked without any problems, but I don't know how long the battery actually lasts. I confirmed the operation of the touchscreen function, button functions, and Bluetooth connection, but I haven't checked anything else because I don't know how to operate it. Therefore, it is being sold as junk. Due to the item being junk, the overall condition is poor, and returns are not accepted. Please purchase only if you understand this. - Brand: adidas - Model Name: miCoach - Color: Black - Belt Material: Rubber - Sensor: Heart Rate Sensor
