This is a review of the 18mg Coffee flavored e-lquid from TrueVapor.com. In this review I go over my opinion of True Vapors 18mg coffee e-liquid from taste to vapor production. All of the e-liquid reviews that I have done for True Vapors have been with the Titan 510. I think the coffee flavored liquid that I have tested from True Vapor gave off a nice coffee taste. It is probably the equivalent of anything you would get from an e-cigarette supplier.
