Not too long ago, I have bought diffuser oil from Natures Garden, 1 sample of FO and the reeds (Diffuser kit with box and glass too). You need to mix it the way they state on on their website. I only bought 1 diffuser kit and absolutely loved it and the whole room was filled with fragrance for 3 months at least. I only turned the reeds once a week. I will certainly be happy with results like that when I start making mine!!!
