Hi, I just received a new itaste VTR v.2 in the mail today and I'm pretty sure it's defective. I just wanted to check in and see if anyone else has had this problem.... ? The top rotational wheel that the "function key" sits on top of won't budge. (The top dial wheel that controls the variable voltage/wattage.) I've tried turning it with differing degrees of pressure but it still seems completely frozen up. It came this way straight out of the box. I'm a bit disappointed as this is my second APV. Has anyone else experienced this issue? If so, how did you fix it? Or should I just immediately send it back for exchange/return? Any advice/help would be greatly appreciated.
