I've also heard mixed reviews. I bought a 50ml jug of Enan, which I then immediately started reading exclusively bad reviews about.
Next I bought some 10ml vials from a reputable source, but the batch number was never posted to the web site. Additionally, the batch number was newer than the newest one listed on the site, yet curiously the expire date was older than previously listed batches.
I gave up, chickened out and ended up buying my oils from a well-reviewed UGL.
