A lovely item to grace your quirky environment. I have to say that putting in a battery and having a tiny bead of light didn't appeal … and I'm glad we didn't do it: for a start, the cones I'm using leak a gluey black substance that would invade the battery housing in the bottom and cause heck knows what. There also seems to be no on-off switch. But I love the way the smoke trickles thickly down the steps into the various basins. It's the year of the dragon, so this item is very welcome.
