Tips:
Please DOUBLE confirm your lens size before purchase via checking your lens thread size instead of camera model name,Your camera's lens thread size will be marked somewhere on the lens barrel. This number is always preceded by a "Ø" (diameter) symbol. Eg. Ø55mm=55mm thread size; some buyers only check their camera model instead of lens model, which may purchase wrong size
Explanation of "X" cross issues: "X" cross on images is a common issue with wide angle lenses and variable ND filters. Physics limit the capabilities of variable ND filters on wide angle lenses. When you enter the edge of the max range,the "X" issue may appear on your image.due to the particular angle of the two polarizers when approaching max density
Color Shift The color of the image may vary between warm and cold. This is a common phenomenon of all variable ND filters. You need to adjust your white balance accordingly when set the ND filter to different ranges
When to use Auto (AWB) or Custom White Balance If you have mixed light sources, such as tungsten light inside and some daylight from a window,then select AWB (auto white balance) and it will do a pretty good job of balancing them. You can also choose to set a custom balance. The short description of how to do that is: take a photo of something neutral (a white paper or a grey card) and tell the camera "use this as neutral" using the custom White Balance settings. Each camera is different, once again you'll need to consult your manual on how to do custom white balance

Try an ND, or neutral density, filter. ND filters reduce the amount of light entering the lens. This makes it easier to achieve effects such as a shallower depth of field or blurred motion.

vignetting
I have hope for this filter to be good, but he have to much vignetting. I use this just one tine when I buy and never again.

I think the 37mm K&F Concept ND Filter is good.
I had never heard of K&F before, so I was a little worried, but there were no problems with the image quality.

Before I bought it, I had read reviews about other manufacturers' variable NDs that showed strange patterns when the ND value was increased, but there were no problems with the Olympus 45mmF1.8. (Is it because it's telephoto?)
As expected, the highest ND value changes the color, but since it's just the color, I wonder if I can correct it as much as I want later.
At this price, I think it's a good product.

It will be shipped from Hong Kong, so it will take some time to arrive.
I think it would be better to order early.

I like the thin one, but I wonder if it's thin.
Then the filter diameter will change. 37mm → 40mm (probably)

Considering the price, I think it's totally worth it.

Good but not that good
I’ve been using it for some time now but I realised when it’s time to take that perfect photo I tend to remove it from the lens because there’s a very slight change in colour with the K&F Concept filter on.

Great and info
For the price it is great, perfect for beginners or someone on a budget. If you are wondering what size to get look the your camera lens and there should be a 2 digit number. That’s the size you need. Works great on my a6400

Would be better if the filter stopped at max and min
The K&F Concept ND Filter does not have a stop, it will continue to spin all the way around. Though it does spin freely, taking the camer in and out of a bag/case may change the filter intensity. Otherwise it allows for much lower f stop. I use this while filming outdoor shots.

From 1-5 stops, there will be a slight X cross for lens under 24mm. An X cross will appear at the highest stop and can be removed by rotating the filter ring, which is a normal situation instead of a quality issue. 
A
Tested with Nikon Z 7 and Nikor 14-30mm Sline, dark corners are not obvious for 14mm and no dark corners for 16mm.

As K&F Concept ND2-ND400 filters adjusts the amount of light that can pass through with polarizing glass, a colour cast can't be avoided for all the variable ND filters on the market. However, K&F Concept variable ND filters are made by the best coating technology, which reduces the effect of the polarizing film on image color. *Based on our professional test, the colour cast of K&F Concept ND2-ND400 filters is around 290k while the industry standard is 500k. 
A
To avoid dark corners, K&F Concept ND2-ND400 filters are designed in ultra-wide construction so the front side of the ND filter is one size larger than the camera lens. It is recommended to use a lens hood of a larger size. 
A
First, K&F Concept ND2-ND400 lens filter allows changing shutter speed based on the effect you want with the best sensibility and the same aperture. Second, K&F Concept ND2-ND400 lens filter allows creating a blurred background with a large aperture while the shutter speed remains the same. Third, K&F Concept ND2-ND400 lens filter is designed to prevent overexposure and maintain image purity and quality at the same time. *Like a zoom lens, the variable nd filters are suitable for multiple shooting situations. If you're looking for perfect image quality, a fixed ND filter is recommended.
