I really like mine. I've only been able to use it for a few hours, but I like the fact that the vape is so consistent from drag to drag. I've used all 3 of my mini protank 2s on it and I've had no firing issues at all. In my opinion, they are the perfect size on the MVP2. My bottom switch was flush upon arrival. No wobble. The fire button is not difficult to press, but this is the only MVP that I have ever held. I have only used clear juices in it so far. I have no idea what their PG/VG ratio is, but I can't go any higher than 7W before they start to taste bad to me. At 6.5W, it get nice thick vape and excellent flavor. I have not tried the iClear 30 yet.
