I adore my Tzumi Lava Speaker. I liKe the green flow of lava with blue liquid. It is easy to set up with my phone’s blue tooth and the speaker sounds pretty good. Sometimes I just enjoy watching the lava since I had a lamp as a kid, so love the nostalgia of this. The wavy design of the glass lamp with speaker gives it a big upgrade from the lamps in my day. This plugs in and the lava takes a little time to get going with first use. It’s pretty in the dark and my kids love this lamp too! We have ours in the family room for everyone to enjoy the lamp and music. I received this product complimentary for testing purposes.
