Works Well But Be Warned...

I followed the instructions and it worked as promised. You do have to follow all the steps though. WARNING: If you’ve duplicated a picture and edited it (straightened, cropped, etc.), it still considers these duplicates and you can’t tell which one is which in the preview window, so you may be deleting the one you edited. Be careful. Other than that, it is a great product. Deleted over 1G of duplicate photos.
