I'm amazed at the quality, everything you need is there and for the price it's great. The only drawback is that the filter holder sits a little loosely on the adapter ring, but that's complaining at the highest level. The moss lip on the ring gets an extra plus point, so no light can enter from the side. The function is given, which would be nice to have an additional slot for a third filter that you can screw on if necessary

Anyone who expects a perfect fit will be disappointed. The adapter rings wobble in the filter holder. The material makes a valuable impression. Since this filter holder will only rarely be used by me, I will not be sending it back. There are only 3 stars because of the 6 adapter rings supplied

Well made, great value!

All in all a very good filter system - the price is also okay! The holder is practical & the glass filters are great - I find them better than plastic filters! A larger bag would be practical & K&F could actually change that, but other manufacturers don't supply a bag at all, hence all the points in the end!

I've been using the filter for a while now. What strikes me is that the build quality is very good. The graduated filter sits tight in the guide. So far I haven't had any problems with the system and have been able to take good pictures

CONCLUSION: The only bad point is that there aren't enough adapter rings. Otherwise a good product. In terms of costs, it is also in a good range. That's why I would like to give 4.5 stars because the quality is right

Advantages: large, 92 mm polarizing filter, easy to rotate in the filter holder, filters come with plastic frames with grip lip, practical filter pocket, unfortunately only for the square filters, polarizing filter and holder, graduated filter too large. Disadvantages: Filter does not seal the light on the holder properly, there is a gap of 0.5 mm, only 2 sliding filter inserts, filter holder has some play and rattles a bit.
The ND 1000 has a magenta color cast and is easy to correct in image editing. All in all, the advantages outweigh the benefits, I can only recommend it. At Rico Best “filter photographer”, you can buy a plastic protection, “filter guard”, there are different sizes, order the right one.

If you don't want to spend a lot of money, take this set.
Bag for the holder unnecessary (environment), because you need another bag for the filters anyway.
Very high quality processed.
All in all very recommendable.

For a while I had been hesitating between several brands to choose a filter holder for ND and GND filters. I took advantage of a flash sale to buy this kit. I am not disappointed.
The set seems sturdy and easy to store.
The case, quite pretty, has 5 compartments, 3 of which, for square ND filters, are raised via a ribbon. On the back of the case, there is a belt loop and a belt loop. I would have liked a slightly more spacious compartment to house the adapter rings with the CPL filter when it is removed.
The assembly (or disassembly) of the elements is well explained in instructions in several languages, including French.

Main positive points:
No dominant color, nor loss of sharpness on the first tests carried out.
The plastic frame with its tabs to handle ND filters.
The system for installing the PLC filter on the filter holder.
the knurled button for mounting the adapter ring and for rotating blocking the filter holder.
The very accessible wheel to control the polarizing filter.
The sturdy holding of the square filter on the filter holder.
The robustness of the metal filter holder.

If you have to find slightly negative points: Keeping
the square filter a little too sturdy in the filter holder.
The click too loud to lock the CPL filter in the filter holder.
No pouch to independently protect the CPL filter in the case.
No protective cover for the CPL when the set is installed on the lens.

My favorite is the polarizer as I like removing reflections from windows and water etc. But once it's on, I tend to leave it on for a while, so overall usage speed doesn't make much of a difference. I would still have the ease of use and speed sooner though :)

Very easy-to-use system
Top product
I've never regretted the purchase.
A great concept in all.
