Rated 4 out of 5 stars

Excelent idea, but I think it has to perform the test in batch. In the present is very slow and takes a long time.
I have many Eric Lee (...example...) in my contacts, and the process request my continuos attention - skip skip skip...
The best: find out all the duplicates in batch and manage them in a second step.
