works fantastic. Connected to my audio video system & can play what I want all over my property and buildings. Purely entertainment for me. I did have one channel dropping out after 4 years of steady use. I took it apart and resoldered the main circuit board. Fixed my problem. The unit is very repairable and easy to work with way after the warranty.
