"I ordered and recieved a "Maycom AR 108AE Scanner" to use to monitor ATC transmissions as a part of my flight training. This scanner worked for about two months, then then next time I tried it it was dead. The website advertises a "risk free 1-year 100% total satisfaction guarantee", so I tried to contact them. The won't return any of my calls, and the only email contact I've had is a promise to "get back to me". That was three weeks ago, and I haven't heard a thing from them."
