An email from James( kuching) after using the SuperMas sound few month ago:-
Wow!! your Supermas sound really working, man. Today morning I was going to check whether all speaker are working well, the time I walk in the entrance with light, Wow!! so many swiftlet that I never have before, round 80 of them flying around the main hall , I was so shock and happy after I saw so many bird shit on the floor. Please recommend few more good sound that I must have.
