Many photographers poo poo these products as inferior but I haven't found this to be the case. For newer photographers on a budget getting their feet wet these are great filters.

The ad saying ultra slim profile I don’t see it being slim at all

Product very well packaged. The storage box is very practical. The product seems very solid, the ring rotates correctly, no optical deformation or coloring. I recommend

Perfect for my needs. I shoot a lot of video outdoors and since I can't change my shutter speed, photos are usually overexposed when I have my aperture wide open. I have used this Nd filter from minimum to maximum and the image is still clear and crisp. Fits my Sony 24-70 g master perfectly

Perfect, the adjustment is very progressive and practical, no chromatic aberration, the sharpness is preserved. In short, nothing to say, it is an essential and very versatile tool that is accessible to all. I recommend.

The filter does not modify the colors and there are no rare vignettes (the famous X). It has a stop at minimum and maximum and marks to fix the intensity, even at maximum does not produce vignetting. The filter is not very big but it is better to put the lens hood first on the lens.

I got this filter for doing long exposure photography, like shooting waterfalls and streams to slow shutter speed and smooth out rough waters. It worked very well. I also shot a very spectacular sunset with it and again it worked really well. The only small negative for me was a bluish color cast when shooting in water. This was easily removed in editing, so it's not that bad. I highly recommend this filter. Excellent value.

I like this filter ideal for photo and video. But at 10mm on my 80D crop sensor, it casts a shadow above. if I zoom in a bit like 14mm, it goes away. NO X, no color cast. Excellent filter... As advertised. and nice build...

It's a must-have item in your camera bag and for a fraction of the cost of other brands of variable ND filters. So far I've tested it with multiple lenses and 3 different cameras using step down rings in low light and full daylight, low ND2 down to DN32 and so far I haven't seen no X pattern. A huge problem with many variable ND filters, even the most expensive ones. Color cast is also insignificant but like ALL inferior ND filters there will be color cast, hell even a $500 will have some sort of color cast, again at a fraction of the cost to have a barely noticeable color cast, or at least one that cannot be easily corrected in LR Nowadays, I shoot with the Sony mirrorless system and every lens I shoot with on my full frame camera has a thread less than 77mm and vignetting is no longer an issue at any filter range and at any what focal length of the lens and i have been shooting the thing a LOT with my sony. Above are some of the photos I took with the filter, including my Canon 5D series and my Sony A7R series. The first 3 are from my Canon and the second 3 are my Sony lens and I've been shooting the thing A LOT with my Sony.

I love this filter! I have it on a 24-105 lens which I pretty much started using exclusively except for a few other lenses here and there. I used to shoot with a Sony FS5 all the time, and its ND filters were about that level. The first screenshot is somewhat color graded, and the other screenshot is ungraded and is from a different camera. I don't think you should compare the two. The important thing for me is to show the versatility you get with your images.
