I have been using this forum for research long before I actually became a member... The advice & opinions are extremely helpful...The know-how & guidance of expierienced users and re-sellers is wonderful... In most cases every member here does his/her best to try to help everyone out to the best of their knowledge and that alone is priceless... This product as incredible as it is can be looked at as an infant in the early stages of life still learning and growing everyday and its people like all of you out there who help to make this product & this industry the best that it can be... I thank all of you for your advice, your input, your help and guidance... If it wasnt for this forum I probobly would have bought this product from a mall or the costco been frustrated and dissapointed and have given up bitter at a product that could potentially save my life or at least help me walk up a flight of stairs without gasping for air... VIVA LA E-SMOKERS!!!
