Supersonic Portable Bluetooth Speaker

I bought this speaker so I could use it for presentations at work. To a group of about 40-50 people it works great. I was able to pair it with my iPad and iPhone 4S. When I first bought it, I was able to use Bluetooth to stream music from my MacBook Pro, but recently, that not has been working. I have been using the audio cable to stream music from my computer. It may be an issue with my computer, since Apple has been doing a lot of updates recently. Once in a while, there is small hiccup in the sound when I stream my music (not sure why though). The only thing with the speaker is that you cannot tell your battery level. Overall, I am satisfied.
