So, the extended landing legs by far are my favorite bit. Gives me quite a bit more room and landing options. Landing in grass, even short golf field trim can be a problem as the gimbal errors out if it can't reset properly or gets moved around. So I fly with the legs all the time now, even if I don't need the other accessories.
As for the drop system, it's nice and easy to use. Not complicated nor does it interfere with the downvision usually. A slight tug on the line and the payload is released. Just watch how much you try to lift with this. It's very easy to overload the drone, keep payloads generally under 1lb.
The light is also very good, I'm able to light up divers entering/exiting the water at night quite well hovering 50-75' above them. My only gripe, which is the same as some others is the position of the on-off button is annoying. You have to turn it on, then adjust the light angle. The other issue with the light is it does interfere with the downward sensors for landing, so you'll have to turn off obstacle avoidance to land easily.
Overall, happy I purchased.
