We love this diffuser! It is completely silent and the moderate heat diffuses just the right amount of oil. Don't worry about unplugging the diffuser-it produces no more heat than an average plug (UL approved - 120V, 5W, and 60 hz). Drop 5-10 drops directly onto the diffuser pad (for best results, use one pad exclusively for each blend) and plug into electrical outlet.

The strength and duration of the scent is controlled by increasing/decreasing the amount of essential oil used. With the simple design and 4 diffuser pads, essential oil blends can be changed easily to suit your needs without messy or complicated cleanups. Grandparents, moms and dads, and teachers report that they find this diffuser indispensable.
