I (Elizabeth) has been testing and using diffuser for at least 10 years. Some products were tested by other experts, and not exclusively by the site editor.
The views and opinions on this site are purely our own, unless I specifically note otherwise—for example, if I quote an expert or something. I am definitely not the mouthpiece or minion of a larger silent highly-capitalized corporate entity.
That said—any product claim, statistic, quote or other representation about a product or service should be verified with the manufacturer, provider, or party in question.
