I like this boothtooth speaker after I finally got it setup and working. I was frustrated at first. It is still charging or at least the red light is still on after hours of charging I'm not sure if it turns off or not. You have to hold the power button on and it makes a bunch of noise and then a blue light comes on. This lets you know it's on and working. The sound is alright. It connects pretty well. The audio cable doesn't seem to work very well. I haven't tried it underwater yet. I will try it in the sink for now. I am looking forward to using this outside and/or around the house when cleaning so I don't have to carry my cell phone around and drain it's battery.
