I bought this a while ago, but I haven't used it at all. I don't remember when I bought it. I didn't know how to initialize it, so I deleted all the files manually. I don't think anything is left, but if there are any files remaining, you can delete them. The memory is probably around 2GB, and the remaining recording time was displayed as about 23 hours. Please check the photos for the condition of the product. As shown in the last photo, one of the tabs on the battery cover is missing. It broke when I opened it to check the operation. However, it closes without any problems. I was able to confirm normal operation, including recording and deleting files, although it was for a short time.
