awesome bi-lateral filter- really rad effect!
Easy to use and really fun. Great value if you need this effect. Construction quality and hand feel is high quality. Excellent clarity and image quality. I size all my FX filters up and then use step down rings to adapt to lenses so that I can get the most out of my filters. I got the 82mm and I stepped this down to 72mm and 77mm.
The look is super cool of the resulting filter. See images attached from my shots at a concert where I used this.

Great Filter But Be Warned it is a Thick Glass
This is a fun filter and obviously for special situations. The filter is built well and threaded easily onto my lens. The rotation ring moves smoothly. The glass is excellent. I had no issues with vignetting or color casting. Due to the way it is made, the filter is heavier than other filters. The weight really wasn’t an issue once I got used to it. The look changes slightly depending on focal length, but it makes it fun to experiment. I found it interesting mixing common colorways as well as stark contrasting colors. Depending on your colors, the filter gives your photos totally different vibes. I have many ideas to try with this filter and I think varying light colors and using gobos will make for some interesting photo sessions. I would recommend this filter to anyone looking for a way to add more creativity to your photography.

Well-built filter designed to stir the imagination
There is nothing subtle about the effect this filter produces. Rather than creating a motion blur that trails from one side, it pinches the center of the frame from both sides or, depending on how you rotate it, from the top and the bottom. It can make framing your subject a bit challenging as the portion of the frame untouched by the effect is smaller than when using a similar but unilateral motion filter. That said, negotiating what is a problem for some people is a creative opportunity for others—an opportunity this filter does not fail to deliver. Even if it does nothing more than help break the habit of someone who by default puts their subject in the center of the frame, so much the better. With so many elements put into motion by rotating this filter I can see how it might be useful for video, allowing viewers to see how the effect develops rather than viewing it as a completed still image. It’s nicely made, the 58mm filter weighing nearly two ounces. The multicoated optical glass rotates smoothly, exuding strength and clarity. Included are three, quality microfiber cleaning cloths and a hinged, padded plastic case.

A filter that benefits from mirrorless cameras and actually can look neat.
This is one of those filters that really benefit from how Mirrorless cameras make in camera preview and autofocus work extremely smoothly. The results are neat to see in real time as you can adjust the rotation of the filter to change the blur effect. I found using it on a 24-70 zoom lens to have a great control of the creative composition and options with this filter, though the effect is way more pronounced at 45~70mms over wide.
While I wouldn't overuse the lens, you can actually get some neat effects with it. It's particularly interesting video wise.
Sample pictures are just random things around the house taken with the filter straight out of camera.

Ok prism effects filter
This thick effects filter renders images as if shot thru a prism. It renders very flat and low contrast images but they can be fixed in post by adding back contrast and vibrance and adjusting the white balance. The filter is thick and heavy, and does not permit the use of a lens shade because you need to be able to rotate it to achieve the look you want.
I am not sure I'll use it much. The effect isn't want I was hoping for and is strong. I have included a few photos of object shot with the filter on and one without.
I don't recommend unless you are specifically looking for that look as it's not that nice of an effect and could be done with an actual prism instead and might render better results.

Unique creative effects and sharp visual quality
This filter allows you to add an artistic and original touch to your photos without compromising sharpness. The glass quality is good, colors remain vivid, and images are always clear, even when using special effects. It can be easily rotated to change the effect and experiment. Useful for those who want to add a creative touch without complications, and the cleaning cloths are a nice extra to keep everything tidy.

Extremely high quality
I have other filters of this type, but they're made of plastic. The kind that cause reflections and lower image quality. The K&F filter is a completely different story.
There isn't a single gram of plastic in this one. And no resin either, since it's made of optical glass on an aluminum support (aircraft-grade aluminum, according to the packaging).
Regarding this, two fairly logical points should be mentioned:
1. It's a heavy filter. If this is a problem for you, you might be better off using a lower-quality, lighter one.
2. If you've never used prism filters, you should know that they can protrude quite a bit. Therefore, you have to handle it carefully, and if using it in combination with other filters, the prism should be positioned above the rest. In the photo, I have it attached to a Black Diffusion filter, also from K&F.
As for the packaging, I've also been very impressed. The package includes a padded hard case for storing the filter and three individually wrapped cleaning cloths.
In short: I love it.
