Does what it says it will

It founds lots of errors and duplicates. The automatic fixes it proposes for classes of problems could use some work. For example, I had dozens of contacts where there was no area code listed. I had to insert the area code into each one, instead of it asking if I wanted to use that area code for all of this type of error. All in all, worth the money.
