These are extremely inaccurate, they don't last the very first hour and some of the bottles I got came damaged. Would not recommend at all, not worth the money. One of the bottles were filled with lemon cologne, it was draining very easily out of the bottle and had no grease on it, which ensures that it is something but not an oil, as described.
I also haven't been informed of the custom charges, they don't tell you anything and you have to pay extra for the customs. Hurts more since you pay shipment by 12$ a bottle.
When I contacted the customer service, they said I was lying about testing them and comparing, like how do you know better?!
