Like many, I was unable to get the DJI filter due to it being forever out of stock. I took a chance on this one and am glad I did. I see reports of the DJI not being able to close, which does create a bit of a hassle for a product that is supposed to be all about ease and quickness. This filter solves that problem by allowing the Pocket 3 to close with the filter attached. See pic.

It seems to be maybe 1/8 strength filter.... it SEEMS a little bit less diffused than reviews of the DJI that I have seen (not in person though). It definitely works, but maybe just not as strong as the DJI which may be a plus or a minus depending on your needs. I didn't see any loss of quality that was not associated with mist filters in general. It did create a beautiful glow for backlit sunny areas and didn't seem to affect colors at all. Really rounded out the sharpened digital look of these small sensor cameras.

I leave this filter on 100% of the time, unless I am using an ND for a more manual exposure. I was able to order a DJI filter as I write this, so I will edit this review if there are any significant differences.

Love being able to just leave this thing on. I can now carry the mist filter attached, and by removing the wide angle lens, I can leave an ND16 and ND64 in the magnetic locations for the WA lens and the Mist filter. Has me covered for 99% of anything I do with this thing. 100% recommend.

Pros:
Cheaper than DJI
Available (DJI is in constant backorder it seems)
Allows the Pocket 3 to close with filter attached
No noticeable color cast or fringing
Doesn't seem quite as strong as DJI

Cons:
Doesn't seem quite as strong of diffusion as DJI
Thin bezel makes it hard to NOT leave fingerprints on it when you remove/replace it
You almost HAVE to have nails to remove it due to the thin bezel
