Worked great with my large Photos library
I ran through the filters several times, broadening the scope for searching and comparing with each round, shaved several gigs off my old and very bloated library.
Well worth the ten dollars considering how valueable pictures can be. Many free/lower cost comparable apps frightened me off, seeing users complaining about corrupting files and losing images in large libraries. Get what you pay for these days I suppose.
