They have twice had my money while I waited for products. Twice, upon my request, I was refunded. I will not pre-order from them again. I have seen some of their founders comments. So, yeah, combative. That said, the filters are great, as you can see in Bryan's review. My experience is the same, I prefer the Breakthrough ND filters over my B+W filters, but not so much that I replaced all my B+W filters. I am about 50/50 at this point. But, when I saw color cast in the Canon variable ND filter, I wanted to see if Breakthrough can do better.
