A great design concept which works really very well. The filters feel and look well made and the magnetic fixing fits firmly. The carry pouch is nicely made too which allows for easy access when on location. This is an awesome starter filter pack for a reasonable price.

The filter is mounted directly on the lens. You can always take it, it is not heavy and you will get great effects with it!
Practice & optical quality:

many voices will say, such inexpensive filters simply can not reach the quality of a brand filter and also I was until now someone who would have immediately affirmed this, so much I was convinced of my B&W, Rodenstock, Haida and Co. filters. But now the surprise, the K&F filters show no abnormalities. No unnatural color shifts, no clear loss of sharpness, hardly any flare and ghosting susceptibility, simply nothing where I would say at first glance that it would be a reason for exclusion. And I think this fact has opened my eyes. Either K&F has found a manufacturer here who also does this for the brand companies, or as I think, they have simply inserted a second layer in the factory and instead of the brand name, simply lasered K&F on the filters.

There is nothing to say about the quality, they are excellent for the price they have.

Very suitable for shooting silky water. High quality glass and threads are indispensable for any serious photographer.

They are amazing lenses

As a photographer, I use filters, but it's not always easy to put on or remove depending on the situation. But with this system, it becomes so simple that it is almost instantaneous.
The product is of very good construction quality and comes with a 4 pockets pouch very well made and resistant against possible blows. It can be attached to the belt thanks to a scratch. The kit consists of two screw rings, one UV and a vacuum on which you can attach the CPL filter or the ND1000.
I wanted to go and test this new product. First with the CPL filter alone and then with the CPL+ filter the ND1000 together. The results are just staggering. Here are the rendered with the CPL filter on the left and the CPL+ ND 1000 on the right. With the filters, there is no loss of dipping, and the color drift is almost zero. The CPL filter polarizes perfectly and the ND 1000 filter is very amazing by its performance, it is very thin which limits vignetting, a plus. Using both together, it is better to avoid the ultra-wide angle focal lengths, but from 16mm, no worries, we can add them up. In addition, they are compatible with my sun visor, I was able to put on and remove them without having to remove it very easily because the magnetic force is perfectly dosed.
Really very satisfied with this first release, I hope that other magnetic filters intermediate with this system will come out soon to complete the offer.
If there were magnetic lens caps, it would be great.
This is a very good investment and the price is more than correct given the quality and results obtained.

I love the fact that they are magnetic, because it's much quicker to change one for the other or remove them without having to screw them on.

I constantly wear the UV to protect the lens and at times when I want to subtract a couple of steps of light or there is water, I leave the CPL fixed.

They are good quality and reasonably priced.
I have tried the variable ones and there is no colour; these are much better, and I forget about vignetting.

The ND 1000 is also very good for long exposure.

I miss that the kit doesn't include the magnetic metal cap, in the end I bought a ND 64 filter loose, so I could have it and I love the speed to have the camera ready.

I love it, it's what it says, and it fulfills perfectly.Quality-price is the best kit on the market

First I must say that I am a Vine reviewer and I received these B08T24T25S Professional Magnetic Lens Filters Kit free as part of the Vine program. The vine program was dev eloped to generate review of new products. This kit includes A UV filter a Circular Polarizer and a Neutral Density 1000 filter as well as a magnetic adapter ring. It all comes in a nice waterproof zip filter case. This is a really nice system, I remember back in the film days there was soothing similar but not as good as this, it was an adaptor with square filters you slide in and out, it was fine except for vignetting with wider lenses. This system is just as convenient but will have no problems with vignetting. It comes with a very slim ring adaptor and the magnetic filters. You can simply keep the ring adaptor on all the time on your preferred lens. It works really well and you can change filters in seconds. In this set you get a UV for cutting down some haze and for lens protection. A CPL great for scenics, reflections etc., and a ND for long exposures, this one is ten stops. This is a great set, I highly recommend.

It’s a great set of mag filters, and they are relatively budget friendly too comparing to most competitors like Kase, Haida or manfrotto. The magnets are pretty strong and the stacking mechanism is a joy to use. Keeps the package slim and works way better than magnetic filter rings from competitors.

One big complaint, is that the filter kit doesn’t come with a magnetic lens cap. The filters themselves are really shallow and won’t hold a clip-style standard lens cap. So without a magnetic cap I won’t be able to cover my lens. Had to purchase a separate magnetic cap from Haida to use with this set of filters……
