Very good quality
I read various reviews before buying this kit and I must say I did not encounter the problems mentioned by other customers. But one of the ND filters I received was unfortunately broken during shipping. I contacted their customer service and they shipped me the new filter for free within two days! Good customer service! After several months of testing, I am very satisfied with these filters, and using them I can't find any degradation in my images. Each filter is packed in a very beautiful black pouch. The filter holder is sturdy and durable. I would like to recommend this product to my friends!
