Bests & Worsts Reviews from Amazon

I bought this product looking for a cheap solution for diluting my essential oils. This seemed to work well, but over the last year and a half, I have noticed a lot of "junk" in the bottoms of my vials. I don't know exactly what to call this process, but it has alerted me to the fact that this is not as high a quality of oil as the one I can get from the same company that I get my oils from. Well, that's what you get for purchasing cheap!
