Hello, this is my first post but I have been reading this forum for over a year. The great people here have given wonderful information that has led to my most recent purchase and what I think will work for me. I have tried kr808's and the ego-T but nothing has worked till I bought the I-pro. Have had it for 4 days. AND 4 DAYS WITHOUT A CIG !!!!!!! Just want to say thanks to everyone here for all the great informational posts that led to this great device.
