Great little speaker!

Bought this for my son for his birthday. He loves it! He owned a previous version but it was stolen and he wanted to replace it with the same. He uses it at chess club at his university in a public space and it works well!

BOOMIN'

I like to move it, move it. I like to groove it, groove it. I'm big on shmoove it, shmoove it. The WONDERBOOM 4 brings the noise, boom-boom. It's a good radio replacement until I figure out how to install my car radio.
