I cannot say enough good things about this speaker. It is built like a Sherman tank and sounds great. This thing is indestructible. We strap it to the atv racks, lay it on a towel at the beach, bounce it around in a kayak and at the end of the day rinse it off and put it back on the shelf. It is an expensive item but worth every penny. We literally destroyed 4 different Bluetooth speakers that marketed themselves as “outdoor rated” before finding turtlebox.
