Crutchfield Customer Review (What's this?)
I ordered two of these, did not find any problems with flaws in the glass. These are older design filters and Hoya has a newer model. There are a few Web reviews of filters and the Hoya HMC is near the top in them. I would only consider the Marumi DHG and the Vue filters as better. My only negative is that these are not extra slim.
