Bests & Worsts Reviews from Amazon

I was really excited about this product when I ordered it. "Made in USA" with a 25-year warranty. It arrived in a nice box similar to Apple iPhone. Unfortunately the performance is disappointing. Whenever I buy this type of filter I do a simple test, shooting against a strong light source and looking for flares/reflections. I ended up having to buy another filter from a brand I was already familiar with (B+W XS-Pro). The B+W XS-Pro costs 2x as much but performs 10x better. I attached 3 photos to this review... Left: taken with this product (X1), Right: taken with B+W XS-Pro, Middle: Taken with no filter.
