This speaker is awesome! It lasts all day at work and is really powerful. I work in a very loud environment and I can still hear the music. It's really easy to pair, just turn it on and scan for bluetooth devices with your phone. The while light changes brightness by touching the top of the speaker, and to change the multicolored light color you do the same. The pause and skip song buttons work perfectly with my Samsung Note 8 while using Pandora, Sirius, or the native music player. Will update review if any problems develop.
