Received my speaker a few days ago. The battery is satisfying: i've been using it for about 2 hours a day not even charging it for the first time. I'm still listening to music now and haven't charged it yet hahahaha So i suggest you all to buy it, it has a very nice sound for his dimensions.
about the bluetooth is not that good about the distance, probably because there were walls in between ( sorry for my bad english, I'm italian hhaha)
