How reliable is Mover.io for syncing data from Dropbox to SharePoint Document Libraries?

I've recently used it for a migration of about 2k OneDrive to OneDrive migrations and it was very reliable and reporting was good. The modified date and user was retained for files with no issue however I have not tested for Dropbox yet unfortunately.

It's pretty quick/easy to set up so I'd say give it a test before ruling out other tools.
