Hello everyone, my name is Rich and I'm from Ohio..........first post. Have been smoking on and off for about 20 years along with my wife. We both have it "limited" now to just when we have some cocktails........once or maybe twice a week. Just received starter set from E51 and are amazed at the results(this may finally be the answer to quit). Very surprised, thought this too good to be true! Quick question, starter kit came with 12mg cartridges which are more than enough and give all the sensation needed and are very smooth to "draw/enhale". Ordered extra 16mg cartridges and when we tried these, they were virtually impossible to take a drag from them. Has anyone else experience this? Is this a defect or is this common when you increase the nicotine mg? In any case, if this device works like it does with the 12mg cartridges which it was shipped with, I can easily see not EVER having to pick up a cigarette the rest of my life, and that is a fantastic thought. Thanks for having a great place like this to gather, share, and communicate....Rich
