I'm sitting here in stunned silence. The main reason is because I burned out on tobacco flavored liquids some time last week. At this moment I'm all about mint/menthol mixed with chocolate/coffee/caramel/cream. Nothing else...... Yet, this double flavor dunhill from MFS is hands down the absolute best tobacco flavor I've ever gotten out of an e-cig (with Kent a distant second, but out in front of everything else). Now, I held off on this MFS juice review for a while for a simple reason: My order had been shorted two bottles because Dunhill and Tobacco were out of stock. And quite frankly, I was going to burn them hard in the review if I never got them. Well, they showed up today and the expectation had been set that it could take a while. So no hard feelings at all. Also, I was given a free bottle of Turkish Blend for my troubles, and it was yummy. In fact, every single MFS double-flavor juice was just that. An atomic blast of flavor. Out of the Prodigy 5v PV...... too much flavor. I actually pulled a 510 out of retirement to smoke this Dunhill so I could be objective. I don't recommend double flavor out of high-volt mods. Your mileage may vary. It's pretty straight forward though. It's my belief that if you like Hilton, or 555, or any flavor that MFS has, you will like MFS's double flavor version the most out of normal 3.7 volt devices. No question. It really is that good. 555 is so nutty you swear you are going to spit nougat. This isn't just great juice, it's absolutely fantastic juice. And once again, at regular voltage, MFS double flavor RY4 is easily the best I've had. It makes me wonder why more vendors don't offer double flavor. The other great thing about double flavoring is, you know that MFS is making (or at least mixing) their own juice. This isn't just repackaged straight from China. So there's no wondering if you are paying 400 percent mark-up. You are getting a best of breed, completely unique product offering you won't feel guilty about. There's a reason MFS has such a loyal following. 24mg with double flavor is pretty friggin awesome. That, and Chris is a damn good guy. If you are patient, Chris will fix problems. Chris has a "you are happy or you get a refund" policy. There's even a toll free number on the page you can call. Can't beat that. Other vendors, take notice. This is how you conduct business.
