Some comments about this we saw on the web:

* /u/The–Strike on /r/BurningMan We used an EcoXGear Boulder and it was flawless. Battery lasted forever, it was loud enough to drown out music from other camps, and it’s water and dust proof. Seriously so happy I picked it up. It also floats, so you can just toss it in a pool or lake and have music!
