I've been buying all these bluetooth speakers for cheapness because I'm constantly broke but I've had no success with them cause I need one that can get really loud to use at work and none of them got loud enough. This one I finally bit the bullet and spent the extra money to buy it and I was overly surprised and satisfied with it. It has amazing sound and gets really loud. It weighs nothing and is easy to carry around. It also has a radio feature for fm radio stations, which is awesome. The only downfall of this speaker is it only has a 3 hour play time. I opened it up and it only has one tiny rechargable battery on the inside which is garbage considering how big the cabinet is it could easily fit a bigger better battery. So I am going to buy a aftermarket battery to add to it. Other then the weak battery that's in it, this thing is amazing and I would encourage people to buy it. It's definitely the best bluetooth speaker I've seen used or heard that I and friends and family have.
