I just can't say enough good things about the Innokin iTaste VTR! I got the Jungle Camo (green) and have been using a Smoktech PBC V2 in it since it did not come with an i30 as I expected. Speaking of missing parts, here is a really good VTR article with instructions if yours was missing the user manual. I love the way they shaped one side rounded and the power button side flat. Although I usually use my thumb, but by using my index finger instead the rounded side fits perfectly in the palm between the thumb and finger. Since I am not a fan of the i30 I wasn't really that disappointed that it was not in the sealed box although I kinda felt robbed, but any 19mm or smaller clearo will work. The new Kanger Aero looks sick on it so I can't wait for mine to get here. If you're on the fence go ahead and get it, I don't think after the first initial price drop they will drop as bad as the 134 did, but I have no plans of selling mine so resell value isn't really a concern.
