This was a clone my girlfriend found about five years ago, from where I honestly cannot remember but, I couldn't stop vaping it for a good three years none stop. I have moved on since then but will still remain a true classic for me. It's simple to make and it's delicious. I would have really loved to try the original Standard version but never had the chance to. I found my coils used to last longer by eliminating the Sour and it is still really nice.
