Terrible product. Waste of time. – Duplicate Remover and Merger for Contacts doubles and Address cleanup Review

I searched "contact dup remover", this is the only product coming up. I tried it and it ran for hours, I do have a over 10,000 dups, then it crashed. I googled the same keyword search, I found "clean up duplicate contact", I ran for over an hour, but with a clear clock-like progress bar, so I know it is working. Finally I got my contacts all clean up. I do not mean to advertise for another product, which I wrote a 5 star review on it yesterday. Now I know why so many people wrote negative review on this product. What a waite of time.
