Hello everyone. As you can see this is my very first post... it's actually only about 24 hours after I learned that vaping was something that had such a strong community centered around it. Let me give you a (hopefully) brief introduction of myself and how I have arrived at this point. I smoked analogs for all of my adult life up until about two weeks ago. At this point I decided that enough was enough and I was really seriously going to quit (but that is an entirely different story). I got over the withdrawal without any major issues.... except for a constant, subconscious desire to want to go through the ritualized habit of smoking. So yesterday I went to my local smoke shop and asked what they had for electronic cigarettes. What they had was the Nicotek Metro which I bought along with the zero nicotine cartos. I instantly fell in love with the concept and have been absorbing as much info as I could ever since. I have a few questions that I haven't been able to find answers for on my own and I was hoping someone might be able to help.
First, I was wondering if anyone knew anything about the Nicotek Metro? Particularly I am curious about its compatibility with other parts (cartos) from other manufacturers. I have included a photo with the threads clearly visible. I will be getting some solid measurements tomorrow at work if anyone needs that data in order to help (I'm a quality inspector in a machine shop so I take measurements all day). For now I can say that the external thread has a major diameter of roughly .250" - .3125" (somewhere in between... metric perhaps).
Second, I am looking into purchasing e-liquid online and refilling myself as the prices for new cartos from my local smoke shop are pretty high in my opinion (9.99 for a 3-pack) and the Nicotek brand only sells traditional and menthol flavors. So far from some experimentation it seems like throat hit seems to be proportional to nicotine content (is this correct) though ideally I think I would like to try keeping to zero nicotine for the most part while still getting a good throat hit if this is at all possible... any suggestions?
Finally, on a somewhat related issue I am really looking at americaneliquidstore.com to make my purchase from as I am really impressed with what seems to be a top-notch quality system. Any thoughts/opinions/experiences on them as a brand/vendor? I can tell that they definitely aren't the cheapest, but I am willing to pay a bit more for a high quality product.
Ok, that's all I have. Many thanks in advance
