Crashes, Useless – Contact Cleaner - Delete duplicates, merge contacts, sync with Facebook, and backup address book Review

My first time using crashed 3 times. When it didn't crash the interface is useless and clunky when evaluating duplicates. Should be able to see them side by side but instead you have to click into each one and remember which one is correct. Don't waste your time.
