I have used K&F filters for my DSLR and they have always offered high quality, reliable filter solutions. This kit is no exception. According to the listing, the kit I received included:

1 x ND2-32 filter,
1 x ND32-512 filter,
1 x tempered screen film
All in a protective plastic case.

Undoubtedly, you are aware of the function of neutral density filters when you look at this product. These do this job perfectly. I didn't notice any difference in color balance and offer you a total of 9 stops of light reduction to achieve shallow depth of field or smooth motion effects in bright light.

I'm not sure I need the full range of the ND32-512 filter, but it's nice to have it in the kit.

Attaching the filters is quick and easy, however they run a bit close when the Osmo is closed, but it closes properly.

Changing the stop position is hassle-free, but if you have big fingers it can be a bit fiddly on the device. I noticed that it is also inevitable that fingerprints will appear on the periphery of the lens. This isn't a fault of the product, it's just the nature of such a compact camera head, which is why I didn't deduct any points for it.

Definitely worth 5 stars
