K and F has really started upping the game.

This filter is clearly high quality and if you're looking for this "look" you've got a winner here.

Pros
-high quality
-included micro-fiber cloths

Cons
-Packaging?
-The filter ring isn't the heaviest I've used (compared to Tiffen for Example), but what does that matter? It either stay on the lens or in the box. I suppose after 10,000 threads on and off you miiight see wear and tear.

So yea, not any real cons.

Another 5 stars from K and F.

They keep making products that give the "professional gear" companies a serious run for their money.

Keep it coming K and F. We're lovin' it.

**update** added a couple pics showing effect on sequins - I may have had a 1/8th black diffusion filter on some as well I'm not certain.
This is a very enjoyable filter whose star tails are far less destructive / invasive than the standard starburst filters. Excellent for direct lines of sight for small scattered LED's, they also add tails to flares from shimmer walls and such, though less organized and pronounced. Comes with multiple microfiber cloths for keeping your whole kit clean this is a good deal for a very functional and effective filter. I don't want to share any of my current images but will try to shoot some just for this review shortly. If you have say a LED strip light with many diodes, like a grow light as an example, the effect is overpowering. For a string of spread out fairy lights it's much more whimsical.

When I photographed my home this spring with a regular starpoint my landscaping lights just turned into a full frame flare-spectacle in a way that was quite distracting, I'm looking forward to redoing that image now with this and it should have a much more quaint feel.

I got the 77mm for use on my 5dmii and have been shooting with my 24-105mm F4.
I will continue to experiment and update this review with more nuance and images soon.

This 62mm variable star lens filter delivers nicely on those starburst patterns around bright lights. It handles both still photos and video without any issues, giving a subtle sparkle that can really elevate night scenes or sunny highlights. The construction is solid, made from optical glass with an 18 layer coating to cut down on glare, and the rotating outer ring lets you dial in the exact look you want. It even includes three handy cleaning cloths in the package. For the price, its a reliable quality filter that adds some fun to my photography without overcomplicating things.

Great Brand And Premium Quality Filter, 4 Point Cross Star Effect Works Awesome, Lens Fits Perfect On My Canon DSLR, Comes With Cleaning Cloths To Keep It Dust Free, Its Own Case Too Protecting It When Not In Use.

The filter is very nicely machined, and has a great matt finish. The ring rotates with a bit of a drag, as it should, and stays firmly in a position that you choose. There is large knurling on the moving ring, for a great grip.

Rotating the ring rotates the 4-line stars.

The filter did not impede my DSLR's auto focusing, although it does cause a bit of loss of sharpness and contrast, it's not dramatic.

The main question is how often you are going to use this filter. It's a novelty filter for a novelty effect. But it can add a touch of magic to a shot with strong highlights.
