For the money this is a really good product! The audio quality is quite good and the range is decent. Installation was easy with several options. Unfortunately the manual doesn't give you much guidance in this area so you have to figure it out yourself. I had to replace the velcro on the microphones because the provided stuff didn't stay stuck on.
