[This review was collected as part of a promotion.] First the box is an amazing bluetooth speaker that sounds really good by itself. The light feature is nice especially if your outside at night and gathered around the pool. For small get togethers or parties it is a conversation piece and for the brave singers the mic is awesome. Volume for the mic is adjustable and it has an echo effect that is nice. You can plug in a guitar and attempt to play along with your favorite song. Overall this is a nice piece and I recommend it for anyone looking for a bluetooth box that has a lot of extras. Battery life is great I haven't had any issues with using it for an entire night and it still has life.
