I just did a tour of V4L and I know their quality control was discussed

I have *NO* hesitations about accepting anything V4L tells me as being "gospel"

If they say 4mg...it's 4mg (or, as close to it as makes no difference) and if they say 36...I'll know to stay away because it's too high for me
As for others, I think that's one reason I haven't "sampled" other products...I did hours and hours of research and was confident about the V4L product (and its users...take a bow, family) before I ordered

I didn't see that many other places who would stand behind their product and their testing like V4L
But, yeah, it's serious news for anyone vaping from other vendors...unless they do as strict quality control as V4L

Scary, isn't it?
