Top critical review

After a while using these diffusers, which admittedly smell nice and wintery (if a little overpowering and synthetic), I noticed that after sleep I would wake up with phlegm and find it harder to breathe. After being advised by doctors and dermatologists, apparently due to chemical sensitivity, I had a slight reaction to the fumes diffused by this product.
Essentially, if you are okay with breathing in random chemicals and keep your window cracked to let some of the strong smell out, this is fine. Otherwise, get something with natural scents in essential oils for a slightly higher price. These seem like good value, but I'd probably say it's false economy.
