A word of warning to anyone who purchased some Haitian vetiver essential oil from Olfactik, prior mid-February 2013 - the oil is actually Javanese!
I ordered some and knew it wasn't Haitian straight away. After sending an e-mail, Olfactik soon replied that some confusion arose between them and their supplier, and confirmed my suspicions that it was of the Javanese variety. The website details have now been corrected accordingly.
I was fully refunded but, if I didn't have much experience with vetiver essential oils, I would have been none the wiser.
