The diffuser was intended as a gift for my grandmother (with Amazon Prime 30). The problem as described elsewhere, is the cumbersome opening mechanism by which presumably not just older people who are ungeschcktere problems. Therefore, the handling is really very awkward, not to say annoying. As device is relatively small and the wood translucent plastic in wood effect, also not to be expected as such a price but different. The lighting is a nice gimmick, but that just at dusk After visible. It is only possible to use fragrance oils. Salt solutions work only in very small doses. The handling is a bit more comfortable than normal tea lights, but the fragrance is for not heated. Too bad, I was hoping for a little more. Because it works in principle, 4 stars.
