Build quality 5 starsthis thing is sturdy and could easily take a drop and still functionbattery life 45 hours of battery life is great it would be nice if it didnt take 5 hours to charge itoverall volume 5 i was blown away by how loud this tiny speaker could be we had to turn it down because it could be heard through the entire housesound quality 4for a 15 speaker you can not ask for much more for the sound quality the tone breakdown below is based on the 15 price tag highs 5 i expected the highs to overpower all of the other sounds which is common in low end speakers but this speaker did not do that

Bottom line if you are looking for a bluetooth speaker look no further
