Pros below: excellent quality, even at night you can see from the phone that it's night and from it it's like twilight. excellent option, compact and well holds height and in a strong wind. Convenient charging for 3 batteries and compact. Has cons: there is not enough wire a little longer to connect with the bodies. when flying in the forest area and lowering the height near the trees, the signal is lost, you need to be careful to find the device later. there are not enough interference sensors on the sides.
