Handcraft Basil Essential Oil - 100 Pure and Natural - Premium Therapeutic Grade Essential Oil for Diffuser and Aromatherapy - 0.33 Fl Oz - Pack of 2 First impressions: Nice bottles of basil scented oil. The fragrance is very strong with no chemical after smell. Installationsetup: Use in a diffuser, in lotions, candles, and the like. Final thoughts: I used this on a pumice stone and put it in my bathroom. I use pumice stones and switch them out. They are cheaper than a diffuser and I can use whichever one I like, I just put them in a vacuum sealer bag when I want to change them out. I like this and Im glad I got it. 1 star - I don't recommend it at all, poor quality. 2 stars - I don't recommend it, it has multiple faults, or a very high price. 3 stars - It's passable, It has some faults but the quality is ok for what it is. 4 stars - Product quite acceptable, it does what it promises. 5 stars - Product that I totally recommend.
