My husband and I love our room scented nicely. We bought an aromatherapy burner, candles, and oils. At the store where we bought our set, they were selling the KingKing line of Potpourri Oil. I think in all, they have like 20 something scents available. But so far, we have tried Water, Sunflower, Citronella, Sunflower, Lavender and Eucalyptus because of their supposed effect on our general well-being.
We love them! Aside from making our room smell good, I think it does wonders for us. Citronella for instance drives mosquitoes away while Lavender does make for relaxing sleep. One time we needed Eucalyptus because my baby had colds, but the store no longer had stock. We went to another mall selling another brand and my goodness, I almost emptied the bottle and it did not even perfume the room. We went to the drugstore and found yet another brand, but it was worse.
With KingKing oils, we use about 25 ml of water and then 5-8 drops of the oil. We then burn a tealight candle and when the candle is halfway burned, we blow it out. The room would still stay scented for hours. It is real value for money. KingKing oils cost about the same with other brands but it only takes a few drops to liven up a regular room.
