I am so disappointed.  This worked really well for about a week then it just stopped putting out the mist and aroma. I keep it in the hopes of it starting again, in fact just this morning I cleaned it, put in fresh water only and it gave a huge puff and then just quit. Everything else works just fine. But I love my aroma and sadly I don't get it. This is really a piece of garbage now sitting by my beside.  I hope you will be able to improve this product so that it lasts for those of us who want to use it. I am super saddened by this product and can safely say. DO NOT PUT YOUR MONEY INTO THIS PARTICULAR PRODUCT.
