Just received my new eroll. I used V-2's until then. The eroll doesn't seem to have as strong a TH as everyone had been posting (not more than V-2 anyway). I hear a whistling sound when I take a drag and I'm feeling like this may be related to the lack of power. Also, the atomizer gets very hot if I take more than one drag at a time. Is anyone else having these problems. I did just send a message to joyetech but I wanted to see if I could get any answers in this forum as well.
