first of all i wanna say thanks for all the good info leading up to this post.... well i ordered an extreme friday based mostly on reviews i saw here.. ordered from a third party cause they were only one state over.. well it was supposed to arrive today when i get this email..that stated we gave the company the wrong shipping add.. well that was funny never change my shipping add.. then we get another email stating that the extreme was on backorder, due to manufacturer back up. so it would be another 2 -3 weeks because when they shipped out the vaporizor to the wrong add. when it came back they opened it and it was broken..i asked for a refund and put an e mail into the guys at arizer to see if they are truely on backorder...man i should be inhaling a bag of vapor right now. instead i am not....
