After receiving additional information about the product, I am changing my review of this product. This is a great price, the lights are cool to look at at night. I have been informed that although the instructions state that you can remove the center piece to add an aromatherapy pill, this is no longer the case because people have lost the center piece. I've been told that you can put a drop of aromatherapy on the button and still get the same effect. Great product, wherever I go, people just love it.
