Lenses arrived but the ND4 filter was cracked. I reached out to the company to ask for a replacement and they shipped out a whole new set for the trouble. I was impressed with the response speed and their willingness to make things right. The lenses are decent quality as well. I've used the circular polorizing filter to take some great shots of river otters, using the filter to eliminate glare off the water surface. If you don't know the filter is meant to be turned while you look on your screen to find the best angle of rotation for glare reduction since this is variable. While it won't kill it completely, it will reduce glare significantly and improve the picture quality. The UV filter is great quality for the money and I took pics with and without and saw no reduction in quality with the extra glass in front of my lense. I have not used their ND4 lense yet but I did purchase their Nano ND1000 lense to take some long exposure shots and the nano line is even better quality glass and worked perfectly. While I did see a slight color shift I was able to fix in post without much effort. Pretty much par for the course when it come to heavy ND lenses based off my research in the matter. Overall, I feel this is a good buy for the beginner photographer like myself that wants to dabble with lenses and not spend a small fortune. I will say you need to spend a minute cleaning these lenses once you get em since they have some fibers and smudges on them. I would assume this is standard practice at this price point.
