Nice idea but nearly dysfunctional

Overall
* Almost dysfunctional due to sync errors
* Sync stops when file names are too long or files names include odd characters.
* Account management a pain

Advantages
+ Fast sync (when it works)
+ Good options for sharing files and folders
+ Good integration with MS Office 365. You can save directly to your OneDrive.
+ Shared presentations and text can be viewed online by people you shared them with

Disadvantages
- App crashes when file names are too long. 250 characters. Sounds like not a lot but happens more easily than you think.
- App does not sync files with odd characters in the name, like %#<>/|. What is worse is that you cannot look for these files. As soon as you open the log file the app freezes
- For business users the account management is for too complex. My IT hates the app.
