Premium Pine & Metal Bluetooth Speaker - Wireless Portable Speaker with Rich Bass, 12H Playtime - Perfect for Outdoor, Travel, Home & Party Use

I will say first off I did not buy this from Amazon but did check Amazon reviews when I went to buy it on a whim at a cheap discount store (I could have gotten for less on Amazon). There was only one review at the time, one star, saying it had a small amount of battery time. Fortunately I decided to buy it anyway. After fully charging it up I use it to work out with and already have over 3 hours of play time and going strong....I am sure I will have to charge it up soon but more then adequate for what I need it for and has great sound!
