Bought a Samson concert 88 system with an aeromic. Had it just over a month and the transmitter was going and cutting out the sound. In 30 years of teaching this has never happened! AV had me contact and work with Samson. It's been over 2 weeks since they've had my mic and after contacting them this week, I've heard nothing from them! I teach 6 days a week and need my mic back now! AV SHOULD HAVE SENT ME A REPLACEMENT ASAP SINCE THE MIC WAS JUST OVER A MONTH OLD!!! I've ordered mics over the years from AV. This is terrible. Don't think I'll ever order again or refer AV as I have over the years.
