Simple, easy to use. Potentially a great spacesaver.
I can't trust it so very time consuming
This is great for de-cluttering and removing screenshots and blurred photos etc. But I found that for 'similar' photos, it chose the best one for deletion too often. As it found over 2000 similar photos, I would have lost a lot of time checking every one of its choices.
In the end, I cancelled my trial and deleted it.
