    After trying RY4 from more suppliers than I care to remember, I finally found one that got the mix just right.
    I can vap this for days and still be surprised at how good it is when i take a drag.

    This is my favourite. Most like a regular cigarette. Really good!

    I have been getting RY4 since I started the e-cig and it is still my favourite. Have tried a number of other flaovours but always come back to this one.

    Once I found this flavor, I was hooked. Then I found RY4 x, but it has disappeared. So I reluctantly go a 50%/50% RY4 from Crystal Liquids.

    This is now my favorite. I discreetly vape at work so I mix it with 1/3 unflavored. The caramel flavor on my tongue is magnified for some reason with this mixture.

    This is a ADV for me. Very clean taste in the 50/50 formula and doesn't clog up my coils. Wish it came in a bigger size. Very good juice!
  • Author: Kim
    Perfect. Just like the description says; mild tobacco with a hint of caramel. Not too sweet, nice throat hit. Beautiful. :)
  • Author: Saad Alfouzan
    This ejuice is authentic. you can't vape enough of this juice. 99% of my business is with crystal eliquid and this one is most perfect juice.

    though taste is subjective, I guarantee you will be satisfied with it. just go with 30ml

    I know experienced vapers love it, but maybe you're new and wondering what RY4 tastes like, and why it's so popular?
    RY4 tastes like cigarettes smell when you first open the pack, like caramel and vanilla and tobacco and heaven.
