Mad Vapes Cherry Blossom has been my main juice for over a year -- long enough that my nicotine addiction "attached" to it, and when I started vaping other flavors I'd get that old "wrong brand of cigarette" craving: "Yes, yes, that's very nice. Can we have a real vape now, please?" (It only lasted a day or two.)
Their delivery is speedy, prices are good, and I can't say anything about their customer service other than that in 18 months of ordering from them I've never had to contact their customer service... so there's that.
