Bought two of these last week to take away on a long weekend and were pleasantly surprised! For such a small, portable speaker, the sound is brilliant! Unlike the speakers I had before, no batteries were required, which was one of the selling points for me. I could easily recharge it with the cable supplied...although we didn't have to even after three days of persistent use! We bought two so we could connect them up, and although I was suspect as to whether it would work...I was again thoroughly impressed. They really do boost the volume when connected with no decrease in quality. Would highly consider picking up some additional colours for the future! I would definitely recommend them and are much better value than more expensive alternatives.
