This is my first mathmos lamp. It lost about an inch and a half of liquid in shipping, but I topped it off with distilled water. I am absolutely amazed by the way this lamp flows, and by how vibrant the colors are. I can't capture it on video. I still have to get parts to rewire the base, but it is also of exceptional quality. The only problem is, now I want more mathmos lamps, and they are difficult to get in the US!
