Pendaus- Im vaping an RY4 right now, and I totally get the "blueberry" thing! That's so funny. I would have never even thought of it unless you said it, because I have "caramel, nutty, blah blah" set in my head.
That being said, I am not digging this RY4, at all. I got it in the mail today, and it will be my last delivery until Tuesday. (So I'm going to have to vape it, as it will be my only stash) I posted a thread in another subforum asking what store bought ingredient I can add to it to make it taste different. It's just gross.
