Fun! I did not expect the features of this lamp, thinking I'd ordered something more plain. The solid side illuminates in a circle and the tone is adjusted by a toggle switch on the cord. The switch is a double switch, one for the solid lamp and one for the kaleidoscope side. They can be used individually or at the same time with this switch. The lamp is sturdy. It was a little clunky to put together, I recommend doing so on a soft surface like a couch or bed to protect the lamp. It is relaxing to watch the moving side of the lamp. Like being underwater or in bubbles. There were color change attachments provided although I did not try them. The lamp is well built. It's a little tricky getting the cord through the tubes, you'll need to take out the threaded part each time, but it goes back easily.
