I pre-ordered mine from the same vendor yesterday, and got a nice email from them just to make sure I knew that it was a pre-order.You got a good deal. I just pre-ordered a replacement top head from ecigaretteimpressions.com since they're currently out of stock. ETA 11/18/2013. The price is now $5.99 for chrome or black chrome, $6.99 for brushed steel. Though the shopping cart page says free shipping with orders over $10, the shopping cart does not remove the shipping charge until the order is over $20.
The thread issue is the only fault I've found with the V2 in the 5 months I've had it.
I like that kind of service.
Looking forward to taking my Vamo off the injured reserve list. I just hate the way it looks with that air flow controller on top.
