Black Note in my opinion is the best in every scale, First, I like Their transparency, when you surf their website, it’s simple and perfectly-arranged. They know exactly what vapors want to know about their E-Liquid, and this is a very very important thing to me, they are aware about the suspicious ingredients in the market E-Liquids and they say it clearly that they don’t have any in their E-Liquid, for me this is so professional and appreciated. Second, I purchased some bottles (Jazz,Prelude and Rock) and received a Quartet and a 4 small bottles book note as a gift from a friend, and they are all AWESOME!!!! The taste of every Note is unique and nice, I really liked them all, all are great, everyone with its unique taste. Third, customer service is fast (i sent an email asking about somthing and I received the answer very fast), very good and professional. The shipping is so fast and i like the USPS priority mail service, great choice from Black Note. Packaging is beyond perfect!!! Its like ordering a piece of Art ... In my opinion Black Note E-Liquid deserves such a wonderful packaging. I wish you (Black Note) all the best, keep up the great job.
