I love the evods! But just be careful to what e juice you put in them. They are plastic on the inside so you can't use any strong citrus flavors or cinnamon or especially lemonade flavors. I accidently put some pink lemonade in one and it fogged up in minutes. But bakery and tobacco flavors will probably be ok in them. I use Butter Pecan and my sweet flavors in them.
If you find you really like them then you can try these....
Kanger ProTank II They make a mini version as well and they take the same heads as the evods and since they are glass you can put anything in them without worry. And this vendor is very reliable I use them all the time.
And keep that E cig alike handy..I had one that I used for those stressful times when I thought I really needed one and it always did the trick but now I hardly use it at all. And if you don't already make sure to have at least 2 batteries at all time in case one of them decide to die on ya...same thing with the charger. Always have 2.
