Well I just tried my first "e cig" as a cheap trial from Gamucci. Picked it up on impulse at a convienience store. Interesting and liked it enough to want to explore. My 2nd sin was ordering the "Free Trial" from Smoke Star which I now find out isn't a "free trial" Since I havn't gotten it yet the only experience I have is from the one Gamuci I tried. My questions really surround my ignorance of the whole process. #1. Do they ALL have a little button on them you have to press each time you puff? My cheap test unit has a button. Maybe it is just there because the battery isn't rechargable. #2. What is the best outfit to get hooked up with? I don't want to have problems getting refill cartriges in the future. I am used to just going to the store and buying a pack of smokes so ordering and waiting seems like a hassel. #3. I smoke about a pack a day of Marlboro Reds. What nicotine level is the same as that? #4. How long does a cartrige REALLY last? A packs worth or more? #5. I get very little vapor from my cheap test unit. Seems like I have to work hard to get much and then that makes me cough when inhaling which regular smokes never have.Another downfall of the cheap test unit? #6. Is it really as safe as they claim? I know that reg cigs have 4000 + chemicals but then any flavoring, whatever would also take chemicals to create. Understand that I don'tcare about smoking anywhere so much as I want something less damaging to my lungs. 50 years old and been smoking for 37 of those.
