I've been using it to clean fruits and vegetables. Had to put it outside though because of the strong smell. I've been using the cylinder shaped stone, but it also came with one shaped like a ball. Nothing in the instructions indicates what the difference is. Otherwise it's very simple to operate.
Bulbs were an exact fit and heater is now working like new.
