Only issue I have with them is I wish the cases were more compact for the smaller filters as opposed to being a one-size-fits-all. But the filters themselves are great.

Was recently able to use both the circular polarizer and the nd64 on a shoot. Thoroughly liked the results from both, especially the CPL, which was used on the shot shown. As with most filters, be careful not to tighten them down to tightly.
