I don't really need another application. I just need cool hardware to connect, I can upload files and then back them up somewhere else. I don't want cloud BS, I don't want your application to restrict file permission. I just want to share my raw data. This PNY DUO thing works, but I still have to use an application that, with all my data practices, compromises the accuracy of my files. It does not perform any archiving of data transfer in any way. Perhaps this is normal for your child's phone, but not recommended for professional iOS device backups without the risk of data manipulation (overwriting of image files, hence lossy JPEG artifacts) and possible exposure to malicious entities or cloud storage negligence it prompts the user for configuration.
