I scratched the original red filter on my GoPro Flip 3 filter beyond repair. So I purchased the new Flip 3.1 filter with the MacroMate Mini lens.
I have used the Macromate mini lens once and have decided that it is not for me, if I'm going to do macro I'm going to use my SLR.
So I have an original Flip 3 filter with Nightsea Filter (the filter is unused, unscratched and still wrapped in the protective paper.
I also have the MacroMate Mini lens and the 55mm threaded adapter.
After $50 for the Flip 3 plus the Nightsea filter.
After $90 for the MacroMate and Filter.
For people looking at getting both the MacroMate will only fit the Flip 3 if you buy a top flip.
