Query: Claims to come with hanging hooks but doesn't

I'm not sure whether to return this product or not; it cost a pretty penny given how simple a mechanism it is--especially when it doesn't come with hanging hooks (in case the suction cup does not work) as it claims. Got some sunlight today (we live in upstate NY!) so I know it works but it doesn't seem to produce much in the way of little rainbows--also as it claims.
