Terrible system. For the entire two hours, the microphone volume fluctuated between soft and loud. Worse, the speaker kept making a sharp siren noise; I'm not sure if the room was too small. We entered the room a few minutes after 9 pm because the staff was cleaning. However, our time stopped five minutes before 11 pm. We could have still sung a song if Teo Heng at Canberra hadn't shortchanged me and my girlfriend. Lousy system and bad service.
