One of my favourite purchases of all time, I think. I've always liked lava lamps but never seen one of such size (within affordability anyway).
Being of such a size, they do require a high voltage light bulb which uses a large amount of electricity. Also, the lamps do take more than two hours to heat up and flow properly. But I think they're well worth the wait.
They only come in two colour options: purple/red and blue/green. They could do with having more colours but I have the red and purple one in my room and it is a brilliant talking point to any visitors that come around.
I paid £40 I think and that is a great bargain, specially compared to the Mathmos 'Astro' I think it's called.
