Good sound from a little speaker Review by gmoney
Haven't actually tried the speaker out in the pool yet, but tested it out in the house and it sounds pretty good. After reading the instructions, it suggest not to submerge the speaker in water as this may damage the electronic components. I guess its not "completely waterproof" as it says in the product description.
