Pro:
What I find very beautiful, the individual filter discs come in two practical, padded cases / bags. These are there well protected from dust and damage. The accompanying microfiber towels, although very simple quality, are a practical bonus quantity.
Cons:
What bothers me a bit is the very cheap processing the filter mount. Also in my eyes very annoying, that's much too easy the filter holder on the adapter ring. Here I would have like to have a desired locking. The whole construction rattles something. But good, do you do with something like that even now no action shots. The accompanying "lens hoods" not really deserve the name because it is the be placed on the record it is very narrow plastic frame.
I use the filter set mainly on two lenses with 77mm thread. Everything fits easily.
Conclusion: All in all, a very good price / performance ratio. Man gets 12 filters for a variety of occasions, two beautiful cases to and some microfiber cloths for the care. In the price range hardly Whats better.
