I was on a lookout for a quality diffuser for a while. I read all kind of reviews, bought and tossed some poorly working models, but have not encountered a keeper. Until now. The Zen has a clean, modern look, is easy to use, and most importantly, it mists really well - not too much and not too little. The container has a sufficiently large capacity so one filling can perfume the house for quite a long time. So far, I am very happy with it.
