If you're looking to buy one of these just know sound wise they're not the best, but the functionality is great!! If you keep it at a moderate volume level it's a nice little speaker. It's not a great performer at higher volume's though, and distortion is pretty obvious. If you're looking for premium sound quality throughout all volume levels keep looking, but that's not something I really care about with the roll2 and I'm an audiophile. That's not to say it's a bad sounding speaker, because when not pushed too hard it delivers nice clear sound. I bought mine before a trip to FL, and I am so glad I bought it. Great for beach adventures, or just anything where you're moving. Overall I'd highly recommend!
