A very high quality filter that fits perfectly on the Osmo Pocket 3. It comes in a storage case with a single cutout for the filter, high quality but oversized for a single filter. Either that case should be smaller or more cutouts available. You also get a screen protector which I will assume works well and is the same as the one I already have from K&F. The magnet is strong enough to work through a glass lens protector by K&F and wouldn't fall off unless you drop the camera which you might have bigger problems if that happens. You will have to take the filter off for each use however as it will interfere when the camera turns on and off, this doesn't occur if you don't have a lens protector installed.

In terms of usage, due to the size of the filter, it can be difficult to put it on and take it off without getting fingerprints on it, moreso without a lens protector. This is more of an issue with filters for this camera and its family and no specific to this one. For cutting light pollution, it does seem to work. It does obviously take some of the light away but you can tell that some of the orange light is removed for a more cooler sometimes more natural look.
