Fact-based:
- I launched the backup on my phone (Samsung with USB C port).
- For 8 gigs it took 5 hours.
- I have to stop it 2 times as it was draining my battery.
- The second time I arrived too late, the phone shut down.
- When you are backing up you can't stop your phone, the screen as to be always on.
- As it uses the USB port you can't charge your phone when you do your backup.
- On top of that when you go on the USB key with your PC this is impossible to find your files, they are all renamed in many folders with numbers.
Length of Use: Less than 3 months
Bottom Line: No, I would not recommend this to a friend
