i just put my first order in with health cabin my family will just have to wait untill after christmas to get there gifts i have some kits they will just have to wait for there extra batteries and attomizers and carts and cant wait to get the pass through i like the 510 and got a lot of family and friends hooked on it as well they got rid of all the other models and got 510's i got 10 510's this month alone for family and close friends and just dropped over $300 at health cabin lol a lot of $ . but just think of how much will be saved in the long run and healther my family would be and would save me more $ because when they all need something we could get bulk orders instead of bying 2 batteries here and 3 atomizers there
