I haven't purchased another flavor after I found this.

I’ve had Charlie Noble before, and their flavor descriptions are usually matching the actual ejuice flavor but not this one. Not a single hint of spice or tobacco, this tastes like vanilla creamer and nothing else. Impossible to vape for more than 20 minutes cause it’s so overbearing my sweet. Very dissapointed I spent my money on this

So I was concerned about the synthetic nicotine they use in this formulation. I have never tried the previous formulation without the synthetic nicotine, so I have no way to really compare the difference between the two. I just know that I've heard great things about the pistachio RY4. I went ahead and ordered this one day when it was on sale, I couldn't pass it up. I have to say that my concerns were for naught, this formulation tastes great to me.
