I've used it for video recording and it's great. It has very good quality and I haven't found any vignetting or X marks. I recommend it.

The filter comes with the magnetic adapter to screw onto your lens, but I bought it to add it to my UV filter (obviously magnetic) of the same brand so without needing the adapter in the package. I was afraid it couldn't be added to the UV filter as it doesn't have the same grooves as the adapter (to grip the ring of the variable ND filter so as to allow it to rotate), instead it can be used perfectly even like this.
Fully satisfied.

The K&F Concept 82mm Magnetic Variable ND2-ND32 Lens Filter has some noteworthy features but falls short in a few aspects. Firstly, the magnet quality could be improved for a more secure fit. The noticeable hue-magenta shift, while not a deal-breaker, is something to be mindful of during use. My biggest surprise was the absence of lens caps, a basic accessory that one would expect. Despite these drawbacks, the adjustable ND feature and waterproof build offer functionality. A solid choice with room for enhancement. ⚖️

The product came in nice packaging and with a handy case that can store various filter sizes. The filter looks nice and doesn't glare. I took several photos that look wonderful. I haven't explored many lighting situations yet, but since my main reason for using the filter is to protect the lens, I'm happy.

Great filter! There's no sign of any vignetting anywhere. The magnet is strong and holds perfectly on my 67mm SmallRig adapter for the iPhone 13 Pro.
I think some people leave the included magnetic adapter on and are surprised that the filter doesn't stick properly xD

I never found I needed ND filters of stills photography (I've had a few in my bag for years and never taken them out of their cases to actually use). That's not to say they couldn’t have been used for some shots, just that I've never really needed them for mine. However, when starting to get into video, I'd read that ND filters are a necessity when recording outdoors (especially in daylight)! There are some cheap ones available, as well as some very expensive ones - both fixed and variable density. I toyed with getting a set of fixed ones but thought I'd test the need with an ND, and one in the middle of the price range. I also opted of the magnetic mount as it seemed a useful alternative to having to screw it on.
I've found that ND filters really are needed for video (especially with a camera that works best set at "ISO400") and this one has done the job for me. Variable NDs can suffer from an X pattern at their densest setting - I've not needed to use this one at its darkest but it doesn't appear to suffer from that flaw (well, not noticeable to me). And the magnetic mount is great (a magnetic lens cap was dearer than I'd have liked, but worth it for the convenience).

The filter is good with no 'X' effect at maximum ND. It is larger than 67 at front to avoid vignetting on wide-angles so no attachment for more 67mm filters (eg CPL). They go behind. No lens cap either. It does have a dedicated, marked, rotation ring but the base must be secured with the supplied magnetic adapter as it contains raised portions to prevent rotation of the rear part of the VND filter. It fits other adapters but you have to set the ND value first really as its impossible to keep the base still. No problem if you know what you are doing ;-) but maybe problem for videography. No vignetting on my Sony 20mm f1.8 on an A7R3 so I am not sure what other reviewers are using.

I think that some people have left the magnet adapter (which is included) on and are then surprised that the filter doesn't hold properly xD

I have no complaints about these filters. I run them on all of my portable lenses that are carried. Flare resistance is very good thanks to the coatings, and it's rare that I have to make an adjustment in a shot due to flare. The only exception was when I was taking photos in a museum, pointing out objects near bright lights. But other than that, they clean up well and allow me to walk around without a lens cap for those spontaneous shots.

Fits my SEL100400GM while the lens hood is in place. Granted you'll have to install the magnetic ring first then the hood and then place the filter inside the hood but it does connect to the magnet and since this lens has a handy little slide door(wank wank) I can adjust the variable ND filter...lol..
I'd look to another review of your asking about quality. I'm happy but I'm just a amatuer... if not beginner.
