This lava lamp is the coolest thing I’ve owned in awhile. After plugging it in and turning it on, it did take a few hours for it to heat up enough for the lava to start floating. I love that it’s not only a lava lamp but also has a Bluetooth speaker. When switching it on, you can either choose to have it on with the Bluetooth to play music or without. I of course left mine on Bluetooth which was super easy to connect to my phone. The music sounded great and I could control from my phone the volume that I wanted.  The lava looked so cool and pretty and I enjoyed that I also got to listen to music.
