Have 4 of these in 77mm, a 67mm & a 86mm. For the price, they're good, no noticible image quality issues, easy to wipe water off of. They do scratch fairly easy so depending on your usage you may need to replace yearly, and when used without a lens hood in sunlight or directly into sunlight you get blue ghosting (could be worse, but I remove it when shooting towards sun).
But quality vs cost, these are definitely the best option.

Both lenses are Sigma lenses with 2 different brands of UV filters on them. The lens on the left is my 150-500mm with a filter made by another brand. The right is my 150-600mm lens with the K&F filter. The lens on the left looks a little hazy, while the K&F filter does not.
Does not decrease image quality that I can tell. You can feel that it is weather sealed, but I'm not testing it to see if it truly is.
Comes in a plastic case
So far, no complaints.

K&F makes some of the finest UV Filters for the price. The ring also includes grooves so you can take off the filter easily. I would definitely recommend it to people who have expensive lenses and want a peace of mind.

I’ve always used B+W filters but decided to give this one a try because of the price and was pleasantly surprised by the quality of this filter. The optical quality and fit and finish of the filter is on par with the more expensive filters from Germany.

This filter just helps keep the gunk off the front element. This protection helps keep the lens from slowly getting micro scratches and ruining the whole lens. Easier to replace a filter then a lens.

I bought it for my Canon EF 24–105mm f/4L IS II USM to protect the lens, it threads on and off rather easily and I haven't even noticed it being on. If it does degrade the image, it's not enough to be readily noticed.
