Since I reviewed the SuperTooth Disco, oh so long ago (I still had my Nexus One!), I've never found anything quite like it. It was loud, it was heavy, big, and frankly, a bit silly looking. It was also exceptionally good value for money. It's like that big, old pickup truck from the 70's - a modern substitute is really no substitute at all.
The Disco 2 has made some sacrifices when compared to its progenitor.
