Drone: Mini 3 Pro I haven't used this in any flight yet, so I couldn't speak about its performance. The build quality is first class. The orange CNC aluminum frame complements the tip of the drone propeller. There is no problem with it being too loose. The ND/PL fits tighter than the UV. Again, there is no problem with both configurations. The housing is basic, but the stock drone lens cover fits snugly, so I've heard this has been an issue with other filter housings. In addition, the bag fits in the inner side pocket of your Fly More bag. I asked a question here if there are markings for the vertical like Freewell did, but there aren't. There is one for Hoz. This doesn't mean you can't use it for Vertical, but you have to rotate the filter ring to get the best result. A few reasons why I chose Freewell. This brand has made filters for DSLR and other devices. The specification states that the weight of each ND/PL is 0.7g, which is also lighter than the Freewell. I don't have a scale to compare between the stock, UV and ND/PL. I'll update after a few runs. Until then, if you can get these for a good price then quality wise it wouldn't disappoint.
