It was working, but sometimes the Bluetooth connection was a little unstable. I also feel like the battery drains quickly. Simple operation was confirmed, but I do not guarantee its functionality, so please be aware. I cannot take responsibility after the item is handed over, so it will be treated as junk. Only what is shown in the photos is included. There are no instructions or USB-C cable. Also, considering the dirt and condition, the overall condition is considered poor. *Shipping will be via Yu-Packet Post.*
