Really well designed
I had been hesitating for a while 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 whole thing seems sturdy and easy to store.
The case, quite pretty, has 5 compartments, 3 of which, for square ND filters, are lifted by means of a ribbon. On the back of the case, there is a ring to pass a strap and a belt passage. I would have liked a slightly more spacious compartment to accommodate the adapter rings with the CPL filter when it is dismantled.
The assembly (or disassembly) of the elements is well explained in instructions in several languages, including French.
Main positive points:
No color cast, nor loss of sharpness on the first tests carried out.
The plastic frame with its tabs to handle the ND filters.
The system for placing the CPL filter on the filter holder.
the knurled knob for mounting the adapter ring and the rotating housing of the filter holder.
The very accessible wheel for controlling the polarizing filter.
The strong hold of the square filter on the filter holder.
The robustness of the metal filter holder.

Good product
I honestly don't know anything about photography, and I knew that my partner wanted some filters for her camera. I did some research and they recommended these to me.
Well, I was right, she's delighted... the bad thing is that now she only takes me to see waterfalls

Good value & Quality.
Excellent value for money. Well though out, made and engineered, comes in a nice box, all very well presented. Complete with adaptor rings to fit most lenses. No colour cast that I can see. Im very pleased with the filter kit and have produced good images. Would recommend K&F Concept Pro Square filter set to anyone not prepared to pay silly money for other brands.

PERFECT FOR MY NEEDS...
I purchased the K&F X-PRO Square system. I've used other filter "systems" and most work as expected. These filters fit for all of my Nikon lens filter of diameter up to 77mm (or actually 95mm on the mount). The material and construction is exceptionally well manufactured and well thought out in its design. The included manual is clear and well written for we English speaking/written folks at least. The adapting rings offer "just enough" purchase for screw mount to the lens, so be patience and carefully on the mounting them... could use a few more threads, I suppose. Mounting the 95mm polarizing (CP) is a snap - insuring you position the proper direction. Of course, you have two different ways to rotate the CP - using the handy knurled thumb wheel or to lighten the locking the full frame and/or from the full frame assemble.
Now, since I did not give you ALL of this products 5-stars for a silly reason. The package and the "Storage Case" is over killing! Beautifully packaged, thoughtfully planned for the full system with space for growth. I/most have their own storage and transport camera cases(s) and most do not fill this beautiful storage case! I would rather have had another filter or a more spartan case for individual filter cases for my camera bag... as a trade for the case! For me, I found another small & padded case, for my new K&F bracket + the CP perfectly for my camera bag. AND I had hoped that the K&F offered properly protected for individual square lens w/frame separately purchased - but not with success.
SO - it's not Perfect for my needs - though almost! Although this is my "first K&F product, I strongly recommend based on my first purchase!

Works fine throughout the range on my 10-20 wide angle lens on a cropped sensor. Although I suspect that 10mm would be the absolute limit, any wider and I think vignetting would occur. I don't use the extreme 10mm end that often however I was expecting some vignetting but I seem to have been lucky and gotten away with it. This is a really nice set of filters. Hope this helps.
