Review on Expand Your iPhone and iPad Storage with SanDisk iXpand Flash Drive Go - 256GB Capacity by Kurt Ferguson

This usb drive might work fine but I will never know if it's worth $70 because the iOS app required to use it is a lot too far away is slow to be useful and also riddled with bugs in the most basic functions. The application makes the drive pretty much unusable. The backup on my iPhone XS failed a few times and when the backup appeared to be in progress the tag counters would not load. The application crashed when trying to download the user manual. The supposedly backed up files were nowhere to be found. And my iPhone XS IOS is fully updated.
