I always get filters with non-slip design when it's available. It makes a big difference. I compared it to Hoya HD2. I shot this on Canon M50 with Nikon 35-70mm f/2.8 AF ZOOM-NIKKOR.
1) No filter. 2) K&F. 3) Hoya HD2.
Sure it's not a great test but I can't tell any difference between all 3. The Hoya was visually as good as K&F except it was so static I had to return it. I also didn't like that it wasn't non-slip. The K&F is not static at all and very easy to clean. If there is no reflection, it looks like there is no glass in the ring. A bit like magic. It's very well done.
I use it on my Zeiss 50mm f/1.5 Sonnar T* ZM. There is no play and it fits perfectly. Very happy with the purchase.

I'm usually against UV/haze filters due to concerns about their impact on image quality. However, I plan to use my Sigma 150-600 DG DN Sport (Sony E-mount) in fairly harsh conditions such as shorebird photography, surf photography and sports. So I gave in and bought this filter to protect the front element of the lens.
In view of the fact that this K&F filter would probably be classified in the "middle class" in terms of price, I wanted to test whether it actually had an effect on the image quality. The attached image of a $20 bill was taken in exactly the same circumstances - 600mm at ISO 100, tripod with no OS. As you can see from the screenshot taken in the comparison view of my image editing software, the image on the right (with filter) is significantly sharper and has higher contrast.
I am shocked! I fully expected to remove the filter if I wanted a better picture. Now I can leave it on 100% of the time and just wipe away any spills or dust without worrying about scratching the front panel. Strong recommendation!

I have a Black Mist Pro 1/8 filter that I use quite a bit, but wanted to try a 1/4 for a more pronounced "bloom" in conjunction with a dream sequence I was shooting. I've seen the K&F 1/4 Black Diffusion Filter for about 20% less than the cost of a Black Mist Pro so thought I'd give it a try. I have used K&F filters before and have always been happy with them, although some "professionals" perceive them as lower quality filters. I'm happy to say that the K&F 1/4 Black Diffuser performs every bit as well as the Black Mist Pro equivalent, producing exactly the effect I was looking for with no distortion or color cast. And if you consider the magnetic docking system, I would say that it's even better than the Black Mist Pro filter (this is the first magnetic filter I've used and I'm hooked). This filer is excellent value for money.

Screwing and unscrewing works easily. Used as a protection, even if there is disagreement about whether this makes sense or not. Since I don't want any accidental scratches on my lens, I put a UV filter on everything. Of course, that extra glass takes away some light, but it's very little. This is hardly noticeable in everyday photography. Am satisfied.

I use it on my Canon 24-70 f2.8 II and can't really tell the difference in terms of image quality. So that's the point of buying it and it does its job. The processing quality is good.

Great UV filter that adds nothing to your photos. No color shift, no bluish cast, no blurring... nothing. Just a crystal clear UV filter so you can rest assured your lens is protected. The slim design is nice because it doesn't produce vignetting. This quality is unbeatable!

It is a high quality UV filter, very good construction and the original Canon lens cap fits perfectly.
