Pros

Allows you to see pictures side by side, and some fuzzy logic in comparison, to compare edited versions with those not yet edited (instead of seeing onlly the non-edited with non-edited, and edited with edited) in case you no longer want originals.

Cons

Forces you to rename all your files. All I wanted to do was find duplicates, can't do that without the renaming part kicking in. Renaming wizard starts upon launch and defaults to start upon program start.

Summary

The side-by-side comparison is great. I was able to see pictures that were not 100% alike, because something had been edited, but they looked similar enough that they might be duplicates. The problem was I don't know how safe the deleting is because that is locked (will it really move them to my play it safe folder for further evaluation). My big issue is, however, I am happy with the names I have given my files. I rename according to events (J'sB-day for instance). I don't remember the day it happened, just the name of the event. It doesn't give you the option to leave names intact, and you to put everything into a new folder that it creates. I have a file structure I am happy with. I just want to find the duplicates that are eating my hard drive space.

In short, look for something else. I know I am.
