The main reason for dinging Deadly Sin is the sweetener they use in it. I'm not sure what it is, but it has a very artificial sweetener taste to it that lingers on the palate and in my wicks. I enjoy the initial flavor, but cannot get over the after taste. Unfortunately, all the juices I've tried from them suffer from this. They have plenty of fans, but I'm not one of them.
There are plenty of people who absolutely love Unicorn Juice (formerly Unicorn Poop), alas I am not one of them. Fresh, it had a very medicinal (cough syrupy) taste to it which was very unpleasant. But sometimes juices need some time to blossom and steep before they are good.
I let it steep for two months and it went from medicinal to grandma's perfume. Extremely floral. It probably is just my palette, but it just didn't agree with me at all. From reading other reviews on various forums, you either love it or hate it. It may be a good idea to start out with 6ml to assess whether or not this flavor is for you.
