That cookie flavor is STRONG. It's only day 2, but it's all I taste so far. 1.5% and I think the recommended is 3% or something. It's definitely got a unique flavor. I like it, but I can see how some people would be put off. I need new coils right now, my mixes have been very muted. That cookie flavor though, is like POW. Its got a nice buttery sort of flavor, it's not quite real baked into cookie butter, but not super artificial either. It's reminiscent of the crispy edges of home made chocolate chip cookies, without the chocolate chips. By the time I get my fresh coils it should be vapable. I'll need to make a 2nd 60ml bottle most likely.
So far can't taste the supporting flavors, but again... My coils are shot, so even though I taste that cookie, I'm not getting the full experience.
