I've had one of these speakers for a year and a half, and they are seriously impressive!. First of all, the sound is pretty impressive considering the price, it's loud & as the name and look suggest it's deep and bassy. Battery life over all is pretty good, easily lasting me weeks off the charger with light usage. Also, while its not marketed as waterproof or anything like that, it will survive perfectly fine in the bath, shower or any wet environment, plus it floats ( and yes it still charges ). This speaker is also durable, I've lost count of how many times I've dropped it and it's still fine, over all a impressive speaker for the price
