Well I've been on the e tank for 2 days and it's a really fun cool little device that looks better than any other e cig I've seen on the market,the thing I like is that it is small and is very slick.the taste of the stuff is great I've got vanilla with no nicotine wow does the job with good vyper reliese. 10/10 better looking and cheaper than them in the e cig shops.I felt uncomfortable in the e cig shops as the people in them and got to them are a little on the ruff side.honest opinion vype all the way!thanks very much very professional.
