OK I've only been vaping for a few weeks, but I thought WTF I'm gonna call these companies and see if they're confident enough in their product to send me a free disposable, or anything. 
 
GreenSmartLiving:  This is the brand I've stuck with so far.  They were awesome and are sending me a free pack of their menthol refills, as I stated I was a current user and wanted to try the menthol without having to buy a whole pack. 
 
Blu:  Very friendly, not sending me anything but were helpful (trying) to find a retail store near me that carries their disposables.  I will try if I ever come across but am not driving 30 miles to pick it up. 
 
ZeroCig:  I saw a review on YouTube that ranked them pretty high in comparison to some of the expensive brands.  THE CUSTOMER SERVICE REP ACTUALLY LAUGHED AT ME!  OK ZeroCig I will NOT be trying your product, ever!! 
 
SafeCig:  Customer service rep said they don't typically do samples, but took my email address and said she would talk to the marketing supervisor.  An hour later I got an email asking me what address I would like my free sample mailed to! 
 
V2:  Wouldn't send anything, didn't insult me but weren't overly friendly either.  Nothing said that will make me stay away from them. 
 
GreenSmoke:  Same result as V2. 
 
Encore:  I bought a starter kit and it tastes horrible.  Chemical after-taste every time.  I called to complain, and they were going to email me instructions on how to mail it back to them, and they'd mail me a coupon for a replacement.  I haven't gotten any email yet. 
 
I haven't received anything in the mail yet, made my calls on Friday and today is Monday. 
 
I found this interesting and thought I'd share.   
 
Love this forum!
