This controller transmitter enhances my DRONE camera's functionality so much... The quality of my aerial cinematography videos has improved dramatically since my purchase. Its blueprint is intuitive and responsive never glitches or drops out. The range is above-average, allowing me to get shots from angles that I never could before. The lightweight, compact design makes it easy to travel with when I'm on location. The only con is the hefty price tag, but it`s worth it for the quality. I highly recommend this for anyone interested in video electronics..
