Inexpensive, usable
Apparently, K&F Concept is a Chinese manufacturer of optical components, comparable to eg Hoya in Japan. According to my previous impression, the products are by no means trash, but rather high-quality goods. There are different filters from the manufacturer, tripod, camera backpack...
Compared to the competition, the price is very attractive.
The processing is impressive. I didn't notice any burrs, the threads run smoothly, the glass plates are clean and evenly coated. There are no visible inclusions, scratches or streaks in the glass or in the coating: on the outside, the filters look absolutely perfect.
Conclusion: anyone who, like me, considers anti-reflective treatment to be dispensable, especially with ND filters, can access this without hesitation. The delivery in a set provides flexibility, the reduction values are quite close to the specified values, the processing is good to very good, the color fidelity is satisfactory to good and the price-performance ratio is excellent.
