I had my reservations about this item as I'd heard awful quality sound from similarly sized units owned by others. I was surprised at how well it was built: it's really solid & quite heavy for its size (which is good because you don't want it to move around on the table). The sound is actually excellent, with decent base & no distortion even when you turn the volume up - a huge improvement on my tablet's speakers (but don't expect to fill a stadium with sound!). I was dubious about the battery life but that was dispelled after several hours continuous use. The only down side it's that one can only charge the battery via USB, but if you spend many hours in front of your computer (as I have to) anyway, that's not a problem.
