I purchased one as well, did not work so well . I live at the beach in Hermosa ..alot of interference . I opted to build a signal booster designed for a solo 1 drone and made some mods ... works fantastic I have no more connection issues and it will out perform may battery . I also noticed I have much more control and it never wants to return unless the Battery is getting low. The Range pro is not powered ,so you are paying for a bunch of wires arranged in the head unit , you can do the same thing for very a lot less on amazon with a larger antenna . You will still have to make the attachment moods however you will notice a difference like you neve thought possible . Mine would want to return after 400 ft from lost connection , now I get thousands feet away and still no signal loss. Works like nothing else .. Very easy to set up!
