I bought this from Amazon a couple years ago. It still works great and I enjoy it very much. It is one of my favorite things. Seeing those rainbows in the early morning (I have it in an east window) brightens the beginning of the day.I would think these rainbow makers would also be great for people who are bedridden or don't get around much. Several elderly people I know have taken great delight in watching the rainbows move about their room.
