I just bought this. And the top that goes over the chamber is stuck and won't come off. So I cannot use it. I didn't keep my receipt because I thought this company made good products. I am so disappointed as I saved for 6 months to get it. I have insomnia and lavender helps. So a one-day-old product broken. I am disabled so I had to get a ride to get it and it breaks in less than 24 hours. Since I don't drive I want it replaced. I bought this one because I like Better Homes and Gardens and I thought the product would be excellent. Just the stress of writing this letter is too much. My number [protected]. And you have no site to troubleshoot problems on this product and it was not cheap. Barbara Long
