Review on WinBridge Amplifier Microphone Loudspeaker Waterproof by Tres Carmon

Not a bad product, but the battery life is not as long as advertised when using a microphone. About 8 hours is the best obtained intravenously. If the power drops between 60 and 50%, the speaker will start ticking, which can be corrected by turning down the volume. That loud volume when you first turn it on is annoying when the mic is plugged in and covered. Feedback is brutal. On the plus side. When used as a blue speaker, it lasts more than 13 hours. Its sound is crystal clear. It survives an 8 foot drop from a roof onto concrete with no chassis impact. My 4 year old loves to sing karaoke with him. He likes the included headset. I play the flute and it picks up sounds very well.
