Review on Amazon Exclusive Dusk - Ultimate Ears MEGABOOM 3 Portable Waterproof Bluetooth Speaker by Michael Kosack

Very annoying from the start. When it arrived I wanted to turn it on and start listening to music but it completely died. As soon as I turned it on, it immediately started repeating "Battery critical, please charge." over and over again. Even plugged in and charging it kept making that annoying noise and I couldn't listen to music while charging. It was almost impossible to turn it off. There is only 1 button but you have to hold it for about 10 seconds to turn it off. Overall it was a really annoying experience and the fact that I had to turn it off to charge and couldn't hear it while charging really killed the mood. I wouldn't buy it again
