Ok, if you are looking for a boom box, don't get this and be disappointed. It is meant for local listening around a pool or at the beach. Once you try and crank the music it tends to distort, but if you keep it reasonable, it sounds pretty good. Reasonable base, but not exactly a subwoofer. It does appear to be durable and can take some roughing up a bit. Keep the blue tooth device relatively close and it is alright, but like most of these devices, walk away and it will drop off. If you are using the USB or connecting via audio cable, you loose the weather proofing. These are hidden under a waterproof door, so you have to open it and expose the insides. Understandable, but a pain anyway. Also, pay attention to the size. If you are looking for something to hide in your purse or something like that, it is too big. But, it does perform better than those tiny little things you can hide away.
