Very good finish
It attaches easily and does not allow direct light to enter between support and lens, I am delighted with it, very easy to put on and remove and the filters are of very good quality.
I recommend it for people who are demanding in photography, very good quality.

Excellent value!
Takes a bit of getting used to but the value of a top quality holder, ND filter and a circular polariser complete with several adaptor rings makes this a bit of a bargain. I can even use it on my 14-30 NIKon Z Len’s at 14mm without vignetting once positioned correctly. Pretty impressive bit of kit. The ND is excellent and neutral. Recommended!

K&F Concept Nano-X Pro
I mounted the kit on a lens with the 72 mm ring and it fits perfectly. It's easy to assemble and its operation is very simple, it doesn't require reading the instructions (I'd say it's better not to read them) just seeing the illustrations is enough. As for the quality of the product, it seems to be made with good materials and the finish is excellent; the polarizing filter holder is very effective, placing the filter well and with care and you don't touch it at all. There are two compartments for the square filters that I hope to get the most out of, I'm happy.
As for the optical quality of the filters, I can't comment because I haven't used them yet.

Top!!! Rectangular filter at an affordable price
bought the rectangular filter set directly from K&F. Since I have worked with screw filters in the past and had the problem with vignetting when screwing several filters on top of each other, I have wanted to buy a rectangular filter set for a long time. Since the sets from NISI, Haida and other well-known manufacturers are very, very expensive, as a hobby photographer I was looking for a cheaper alternative. When I saw several reviews on YouTube, I decided on the K&F set, which is half the price of Haida and CO. I have absolutely no regrets about my decision. The filter holder is very valuable and well thought out. I particularly like how the polarizing filter is attached to the holder and how it can be adjusted using the small wheel. The filters themselves are made of optical glass and show no color cast and are also well coated. Another positive aspect is that the filters have a plastic frame with a tab. This allows the filters to be inserted and removed without annoying fingerprints. A bag is included to store and transport the holder and the filters in it. Also included are various adapter rings for different filter thread diameters. As a landscape hobby photographer, I no longer want to do without the advantages over screw-on filters. I give a clear purchase recommendation for amateur photographers and professionals too! I wasn't expecting such excellent quality for this price. It's amazing what K&F delivers here.

Super Filter System in version 2 from K&F
After many reviews that I looked at on Youtube, I decided on the new K&F filter holder and have not regretted it so far. It is easy to use and makes a very high-quality impression. The use of the CPL filter is a great solution. Lever up, put it in and lever down again, done. Adjusting the wheel is also buttery smooth. In contrast to the first K&F filter holder, the filters, which now have a frame, can now be pushed in very easily. Not too easy and not too heavy either. A clear buy recommendation.

The adaptor rings that attach directly to your lens are metal. The filter holder that attaches to the adaptor ring is metal. The frame around the CPL is metal. The detachable frames around the square filters are molded plastic.

This is possible if you don't have a suitable adapter ring. However, caution is advised when reducing larger lens diameters because of possible vignetting.

Unfortunately, only 100 mm wide filters made of glass or plastic with a thickness of 2 mm fit into the holder. I use ND filters 100 x 100 mm and graduated filters 100 x 150 mm.
