It's OK and seems to find duplicates accurately but needs a way to set default KEEP / DELETE options. Reversing the defaults by hand is impossible with 100s or 1000s of duplicates.

You can set which duplicates you prefer to delete in the options: first found, unread etc.
You can also reverse the search direction.
Just experiment a bit, there probably is a setting that matches your preferences.
