Summary:
I love the portability of the speaker. It is fast and easy to set up and bring with me everywhere. I am constantly taking back and forth between home and school. The carry case is great.
However, the worst thing about the speaker system is the ringing that comes from the power supply. It is so bad I almost don't want to use the thing. Mine is not just a flawed product either because I exchanged the whole speaker system at a store in a different state, but the new one rings incessantly as well. I assume all of them ring and it is really hard on the ears.

Pros:
good sound (enough for me) portability carrying case ease of setup

Cons:
Horribly annoying ring that doesn't go away.
