I am extremely happy with this speark. Not only is it a bluetooth, it lights up and becomes a great night light. This way me or the grandkids can listen to music and have a light to sleep by. This is portable because it is bluetooth, which makes it wireless.. Therfore I can take it camping or on a picnic or anywhere I go. The speaker has 5 different colors that it can change to and 2 different modes that i can use. One mode is a fast flash and the other is a slow fade. There is a purple, red, light blue, blue and green lights to use. It is touch activated and also this can support an SD card. You can use an Aux cord if you prefer. I would definitely recommend this to anyone looking for a good quality speaker and light combination! This one actually has it all!
