Query: Mine broke too!

I used this product for about 6 months. It's worked well as a diffuser. Don't expect it to be a vaporizer, because it's not. The moisture it adds to the air is an added bonus, but not what it's built for. However, after about 6 months it just stopped working. It thought mine was as isolated incident, but after reading the other reviews, it seems to be a pattern.
