I have two of these K&F black mist filters -- the 1/2 and the 1/4. I like using these while shooting urban landscapes at night. I know people also use these to make their digital photography less sharp and more analog-like, which seems like a strange step back to me. I have several different photography accessories from this brand, and I've always been pleased with their performance to cost ratio. The filters screw on and off of my step up rings easily; the threads are flawless. The filter comes with some dry, disposable clothes which I find useless and a plastic case which is fine if you don't have another carrying option. The effect of the filter is consistent and very pleasant looking. There appears to be no shift in color from what I can tell. I'm no youtube camera reviewer, but I've tried to include some sample images of with and without the filter. BTW, a pro tip I found online is to buy all filters at 82mm and to use step-up rings for smaller lenses. The larger filters cost more, but all filters perform best in the middle. Plus, if you have large filters, they will always fit any lens when you inevitably upgrade to another lens.
