Bests & Worsts Reviews from Amazon

So I am very "new" to Essential Oils and was looking to duplicate a "spa like" pure EO blend I purchased in London. My tendency is to look at the # of Amazon reviews for a product before reading them because if the numbers are high, then it's obviously a best seller.... right? In this case, I wondered why the prices were soooo vastly all over the board so I was puzzled.... I was just about to buy an assortment of EO's from a "best-seller" but I started reading the negative reviews first. I came across a reviewer who said that most of these companies that claim they sell 100% pure EO's are misleadingly claiming so. While I took that with a grain of salt (hey maybe it was a competitor review?) this person suggested watching a video on YouTube called "Scamazon". WOW did I learn a lot! The video is of an absolute expert in the field of EO's and who scientifically tests them for additives. He exposes several companies on Amazon that are making false claims about their products as well as a few reputable ones. Now from what I understand, having chemical additives isn't necessarily a bad thing but it depends on the application you are using it for. Sometimes an EO "fragrance" is perfectly ok. I am nebulizing mine and I also have pets so I really wanted pure oils. It turns out that for any of these companies to claim that their oil is 100% pure, only a very very small percentage of pure oil (less than 10% if I remember right) is required and the rest can be chemical additives. This particular company was one of the ones tested that did not mislead and did not have "filler" chemicals so that's why I personally made my purchase. Decide for yourself but decide informed! Who knew? I am in NO WAY SHAPE or FORM affiliated with anybody in this industry or in this review... just wanted to pass on my own personal experience....
