- Very good result. It helps a lot in preventing colors from "burning" in strong sunlight and playing with shutter speeds during the day.
- Very nice packaging with foam inside and a magnetic clip.
- It could cost less.
- The placement on the drone's camera is a bit strange, it takes a little time to find it and it definitely helps to place it while the drone is still closed

Although a bit pricey for what it is, 4 very small nd filters, they are good .... they come with a cleaning cloth, a hard case with a magnetic cap, they fit very well and do not affect the image at all. Just be careful when putting the filters on the lens, because due to the size of the drone, its gimbal is tiny and sensitive
