I just got my CE3's in the mail today and they perform awesomely. I got the ones from smokelessimage.com I read that they come with primer so that the 1st 10 hits or so will taste nasty because of it. But as I'm vaping these I'm wondering... What exactly is primer in the CE3's? I tried searching the internet but couldn't find anything on it other than "CE3's come with a primer". Is this something that I shouldn't be inhaling? or is it basically unflavored PG or VG to help it wick for its 1st fill?
