After flying with the Crazed Pilot Bluetooth Adapter for several months, I'm very disappointed. It works well when the internal battery is fully charged, but the audio gets weaker after about an hour and goes away completely after two hours. The really bad thing is that as the audio from the iPad gets weaker, the audio from my COMM radio gets weaker along with it. I have to keep turning the COMM volume up to the point of distortion.
I tried charging it while flying, but doing so introduces unacceptably loud noise in the audio. All in all, I just don't feel like I can count on this unit to give me reliable alerts from ForeFlight. I'm going to dump it.
