I, on the other hand, have had a totally different experience and just ordered 6 more bottles of my favorite... Solo.After reading a few reviews, I decided to take the EXPENSIVE plunge and buy a bottle of Sonata. Upon receipt, I filled my trusty Vivi Nova mini with a new dual coil head. All of this on top of a Vision Spinner II.
I tried taking a few hits and boy was I disappointed. Hardly any vapor and very harsh on the throat. I emailed Blacknote and explained my problem. They wrote back and said he'd never heard of a Vivi Nova mini and "If you could try V2 EX your experience will be much better." I found this on the net and it wasn't all that much different than my vivi nova which I have used successfully for the past 3 years and probably a hundred different juices. The most expensive Blacknote was the worse. My personal opinion is this stuff is a big con job. They wouldn't even offer a refund.
