I was sold 5yrs Knowhow Cloud storage when I bought a top of the range Android tablet, specifically because I was concerned about storage capacity for Word files and pdfs on the tablet. Installed the KH App, wasted 4 hrs trying to backup the doc files on the tablet. First call to helpline suggested uninstalling and reinstalling app. No luck. Then I noticed that most items on main support page had info for Windows, Mac, iPhone and Android, but for backup only Windows and Mac Phoned helpline for comment on this and was told Knowhow Cloud will auto back up only photos and videos from Android devices, not Word files etc! THERE WAS NO MENTION OF THIS WHEN I BOUGHT THE 5YR STORAGE. Apparently files can be backed up individually to the briefcase but this is cumbersome, and I assume the briefcase has much less storage than the 2TB l bought. Not impressed.
