Affordable product, amazing customer service!
I have 4 of these diffusers all over my house and I love them.  My kids love the color changing light and I love that they are quiet, reasonably priced, and most importantly, diffuse my essential oils.  One of them did stop working after about 3 months.  However,I called Now Foods to tell them about the issue and they were incredibly easy to work with and shipped me a brand new one free of charge.
